The telephone can be operated and information on position obtained by sending a text message in the correct format. For this purpose, the application must be turned on in the telephone, text message control must be permitted and you need an authorised telephone number from which you can control the telephone. This can be set up using the following steps.
- Press the ‘Select’ button and choose the ‘Set-up’ option
- Select the option ‘Txt msg configuration’
- Select the ‘Turn on txt msg control’ option
- Enter the telephone number which will be authorised to control the telephone via text messaging
- Confirm the telephone number entered using the ‘Add’ button
- The telephone number can be removed from the list of authorised telephone numbers by using the ‘Remove’ button.
Turning on this function means the application will analyse all incoming text messages to the telephone. If the text message is of a ‘specific format’ (see table below), the application will perform the related task.
| TEXT MESSAGE FORMAT |
APPLICATION TASK |
| POM_A_A1 |
Turn on monitoring in automatic saver mode. |
| POM_A_A2 or in shorter format simply POM A |
Turn on monitoring in automatic optimal mode. |
| POM_A_A3 |
Turn on monitoring in automatic intensive mode. |
| POM_D |
Turn off monitoring in application. |
| POM_INFO_{time} |
In place of {time}, enter the number of seconds from 1 to 60 for which the telephone will attempt to determine the current position of the telephone via GPS, e.g. POM_INFO_58 for a time of 58 seconds. If it is unable to determine position via GPS, it will find its position via BTS. Once the position has been determined, it sends a text message to the number from which the request came in the format:
POM: (Time of positioning) (Method of acquisition (G/B) (Longitude) (Latitude) and a link to http://maps.google.com/ to display the current position on a map.
If co-ordinates were unable to be obtained, the application sends this message:
POM NO DATA |
| POM_INFO |
This text message format is the same as the previous one, but it uses a default time setting of 60 seconds. |
