Setting the Date
The first item on the settings page is the date. Initially you cannot change this setting because the option to use the phone's clock is set. There is a checkbox further down the page that can change this, allowing you to set a custom date.

To begin editing the date, first make sure it is in the highlighted state, where the whole item appears with a green background, eg; 29-JUN-2008.

Now press 'select' to enter the editing state. You will notice that the highlighted area changes so that just the first part of the date, the first digit of the day of the month is now highlighted, eg; 29-JUN-2008.

The value can be changed by using the 'up' or down 'keys'.
The day of month can only be set to a valid number, so because there are 30 days in June, if you change the '2' in the example to a '3' (by pressing the 'up' key), the '9' will be turned into a '0 so that the day becomes 30'. If you were to then change the '3' into a '0' (pressing 'up' again will do this), because you cannot have a day '00', the '00' will be made '01'.
You may find sometimes that in order to set the desired day, you will have to set the month or year first.

To change which part of the date you wish to edit, you can use the 'left' and 'right' keys. This changes which part of the date becomes highlighted;
29-JUN-2008
29-JUN-2008
29-JUN-2008
29-JUN-2008
29-JUN-2008
29-JUN-2008
Pressing 'left' when the first character is highlighted will move to the last digit of the year, and 'right' from there, will highlight the first digit of the day of the month. This wrapping effect is the same for all editable items.

When you have set the desired date, pressing the 'select' key returns to the state where the whole date is highlighted, allowing you to select another item. There is no need to do this if changing the date is all that you wish to do because selecting OK from the menu will use whatever is displayed on this page for the next calculation and will begin the calculation.

Finally, there is a restriction placed on the year, so that you cannot set it to higher than 4000.

Setting the Time Zone
The second item on the settings page is the time zone. Editing of this item is accomplished in a similar way to the date, with 'select' used to enter and exit the editing state, 'up' and 'down' to change the values, and 'left' and 'right' to select which part to change.

'Sun and Moon Times' will only allow a recognised time zone to be used here. Some of time zones will allow a fraction of an hour to be set. When this is the case, the highlight can be moved beyond the second hour digit onto the fraction, or where none has been set, onto a blank space, eg; +10  .

When you select a location from the database that comes with this program, This item will be set to the time zone for that location.

The Summertime Checkbox
This checkbox has been included to allow the easy setting of daylight saving. It will effectively add an hour to whatever the time zone is set to when it is in the checked state (with a cross in the box).

This item has no editing mode, when it is highlighted, pressing 'select' will toggle its state. You can also use 'left' and 'right' here to do the same.

The Select Location Button
When this item is highlighted, pressing 'select' will show a screen from which you can select a location from the database of places that is included with 'Sun and Moon Times'. This is detailed later.

The Latitude and Longitude settings
The two coordinate settings are edited in a similar way to the date, with 'select' used to enter and exit from editing, 'left' and 'right' to navigate the individual parts, and 'up' and 'down' to alter them.

This program uses the degrees minutes and seconds format for setting the coordinates, so the degrees is limited to 90 or 180 (depending on if it is for Latitude or Longitude), and the minutes and seconds are limited to 59 (unless the degrees is 90 or 180, where both can only be zero).

You may notice that when editing one of the coordinate settings, the text above the 'Select Location' button may change. This is because the program will try to find a name for the location from its static database, and if found, it will place it there.

Also, as with the time zone, if you use the database page to select a location, the coordinates will be set accordingly.

The Hemisphere settings
Below each of the coordinates are items to select the hemisphere for them, North or South and West or East.

These work in a similar on/off way to a checkbox, with 'select' used to change their state (the filled circle indicates the current state). Once again, 'left' and 'right' can also be used to change their state.

The Other Checkboxes
The first of these items will set or unset the option to use the date that your phone is set to. When set, you cannot alter the date since it is set from the phone's clock. The program will remember the last manually set date, and reset the date from the current day to this when the checkbox is unchecked. This way you will not lose an important date that has been set when changing this item.

Depending on how many colours your phone can display, there may be another checkbox. This simply shows or hides the background image. On phones with very few colours, this is not shown since the background picture is not displayed at all. Other phones that can only display a limited number of colours do have this item, but the program is set to not show the picture by default. This is because on those phones, the picture can interfere with the readability of the screen.

The Select Location Screen
At first look this page appears simple enough, a field for the countries, a field for the towns or cities within each country, and information on their coordinates and time zone. The way this page operates is probably best described using an example, so we will explain by showing how to select Oslo in Norway.

First we set the country so that we can access the cities in Norway.
When the country item is fully highlighted, you can use 'left' and 'right' to step through the countries (the cities field also works like this). Sometimes it may be easier to do this, but more often you will want to find a country by selecting and changing individual letters. For this example, we will start with the default country for the English language version, which is Afghanistan, and explain this process.

First we press 'select' to highlight the 'A' of Afghanistan, eg; Afghanistan. We then want to find the first country beginning with 'N'. This is Namibia. We do this by using 'up' or 'down' until the first letter changes to 'N'.

Once at Namibia, we want to find the first country beginning with 'No', In the database, this is Northern Ireland (in the database, the British isles has been split up into its main regions, Scotland, England, etc.). We press 'right' so that the first 'a' of Namibia becomes highlighted, eg; Namibia. We then use 'up' or 'down' to change this letter until it becomes an 'o', and our display shows something similar to this: Northern Ireland.

Next we want to move to the next letter that is going to be different between Northern Ireland and Norway. The 't' in Northern Ireland. The next country in the database that begins with 'Nor' is in fact Norway, so we highlight the 't' by pressing 'right' a few times; Northern Ireland, and then press 'up' to reveal Norway.
The country is now set and you can press select again now, which allows you to move to the town/city field by using 'up' or 'down'.

Oslo is the only city in the database that begins with 'O' for Norway (in all but the Norwegian version), so all we have to do here is press 'select' when the whole item is highlighted, so that the first letter of the first city in our database for Norway is highlighted, and then use 'up' or 'down' until that letter becomes an 'O'.

We have now chosen a location. The menu gives us the option to return to our settings page by either selecting 'OK' and keeping this choice, or by selecting 'Cancel', and returning without changing the location.
When we use 'OK', we are returned to the settings page and now have the coordinates and time zone set for Oslo in Norway. The text above the button that is used to select a location is also now set to show this.

So in essence, to find a location in the database, we search by changing the first letter in the current place that will not be the same as for our desired place. When there is no other place that begins with the same letters, up and down will simply have no effect.

You should also note that the database has the States in the USA classed as 'countries' for ease. They are stored as US Alaska etc.

Navigating the Results Pages
Our final section describes what actions can be done on our results display.
There is one page for the Sun information and one for the Moon, and there is more than one way of switching between them, i.e. via the menu, or by using the 'left', 'right' or 'select' keys to switch pages.

There are also a few handy controls that allow you to view the information for the next and previous dates, those are '#' to advance the date by a day, '*' to go back a day, and '0' to return to whatever date was set by the settings page.

The trial version of this program will decide at random if it will show only Sun information or only Moon information each time a claculation is made. A calculation is made when a new date or location is set.

Registering the program
As a shareware product, this program will run in demonstration mode until user registration details are entered and verified via a connection with our website. In demonstration (or trial) mode, the software will have a number of uses limit imposed and will be functionally limited in a way that allows you to explore its features, but not enjoy their full use. The program will also display a reminder message that it is in trial mode. Registration keys can be purchased through our website, and will be emailed to you.

We have chosen to produce our software using the shareware model because we feel that the traditional method of buying a product and downloading it on a phone can be unreliable, and is problematic with regard to deletion due to phone reset, phone replacement, and copy protection.

Registration on the phone can be started by either selecting the 'Register' menu item on the reminder to register screen, or by following the menu sequence 'Help/About/Register'.

The registration screen allows you to provide an email address and registration code. The 'up' and 'Down' keys are used to highlight each of these fields, and the 'Select' key is used to begin the process of entering the actual information. This is done using you phone's own text input control. Once this information has been entered, you may then select 'Register' from the menu, which will initiate a verification of the registration information that you have entered with our website.

During verification the program will send the entered email address and keycode, which is then checked on our system. A code that has been generated from your phone IMEI number will also be sent. This code is stored by us and used to prevent the same registration information from being used on another phone. Because of this, you will need to 'unregister' the program on a phone in order to register it on another using the same email and keycode. The 'Unregister' menu item becomes available on the registration screen once the registration has been verified.

When the registration has been completed, another code and the formula used to generate the registration key is sent back to your phone. This information is then stored along with the email and key that you have entered, and the code that was generated from the IMEI. Each time you run the program, it will check that a matching key can be regenerated, and that the stored code from the IMEI is correct. If any of these processes fail, the program will revert to 'trial' mode.

An additional menu item has been provided on the registration screen that allows you to test that a phone can connect to our website and therefore verify registration. This item is the 'Updates' one. If your phone cannot connect, an error will be displayed. Otherwise you will be informed if a newer version of the program is available. Currently, we allow you to install an update and still register it with the same key. We recommend that you perform this check at least once (note that it may fail due to 'signal' problems) prior to buying a key from us.
