Receiving/Testing Signals
Receiving GPS & GSM (cellular) Signals
Every time you turn your unit on, it immediately starts searching for a GPS
signal, then a GSM (cellular) signal. The following light sequence indicates which
signals have been received:
1. Signal light stays solid blue for approximately 2 minutes while searching for
a GPS signal.
2. Signal light blinks blue to indicate a valid GPS signal has been received.
3. Signal light blinks green 4 times to indicate a valid GSM (cellular) signal.
4. Signal light blinks blue/green alternately to indicate normal standby mode,
ready to use.
Testing GPS & GSM (cellular) Signals
1. To test for GPS and/or GSM (cellular) signals while in normal standby mode,
press the “Test” Button. The unit tests first for a GSM (cellular) signal then a
GPS signal. Sequence of lights is as follows:
1. Green light stays on for 4 seconds if GSM (cellular) signal is OK (no green
light if no GSM signal).
1. Blue light stays on for 4 seconds if GPS signal is OK (if no GPS signal. then
signal light blinks blue for 20 seconds).
