Receiving/Testing Signals
Receiving GPS & GSM (cellular) Signals
Every time you turn your device 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 up to 1 - 1.5 minutes while device is in start up
mode and searching for a GPS signal.
2. Signal light blinks green slowly 4 times to indicate device is registering with
the GSM (cellular) network.
3. Your device will now blink in one of the following ways indicating normal
standby mode, ready to use.
• Signal light will flash green only, indicating the device currently has GSM
coverage, but does not have a GPS position.
• Signal light will alternately flash green and red, indicating the device
currently has GSM and GPS coverage.
• Signal light will alternately flash green and blue, indicating the device
has GSM coverage and no current GPS coverage but does have a position
stored in memory.
Testing GPS & GSM (cellular) Signals
To test for GPS and/or GSM (cellular) signals while in normal standby mode,
press and hold the "Test" button until device beeps. The device tests first for a
GSM (cellular) signal then a GPS signal. Sequence of lights is as follows:
1. Green light stays on up to 4 seconds if GSM (cellular) signal is OK (no green
light if no GSM signal).
2. Blue light stays on up to 4 seconds if GPS signal is OK (if no GPS signal.
then signal light blinks blue for 20 seconds).
• The functions are limited to areas where GPS/cellular service are
available.
