Configuring DSC Settings
Manually Entering Position Information
If you do not have a GPS device connected to your radio, manually enter your position and 
time of entry so that this information will be transmitted with DSC calls. When you enter 
the position and time manually, “MANUAL POS” is displayed on the screen.
Your radio has two alarms to indicate that you need to update your position data:
When the position data you entered manually is over four hours old, the radio beeps and 
displays “DATA IS OVER 4 HOURS OLD” on the screen.
After 23.5 hours, manually-entered position data is considered invalid. The radio 
displays “DATA IS INVALID” on the screen. The radio will not transmit position data 
that is more than 23.5 hours old.
 for more information on GPS alarms.
When you manually enter your position with the time, the time remains fixed at the value 
you specify. The radio updates the time only if you connect a GPS device to the radio.
