PWR Key
PWR Key
To turn on the receiver, push the PWR key and release it.
To turn it off , press the PWR key for more than 1 and less then 4 seconds,
during this period the STAT LED remains off to assist you.
To put the receiver into Sleep Mode , press the PWR key for more than 4 and
less than 8 seconds; during this period the STAT LED is orange. While in Sleep
Mode, any activity on an RS-232 port will turn the receiver on.
If you press the PWR button for more than 8 seconds, it will be ignored. This is
done to protect the receiver operation against stuck keys.
Reset Key
Pressing the reset key for about one second causes:
• a hard reset of the receiver.
• the receiver to leave Zero Power Mode and return to Normal Mode.
Notice: Only use this procedure if the receiver does not respond
to commands or does not charge the internal batteries (is
in Zero Power Mode).
STAT LED
When the receiver is ON and no satellites are tracked, the STAT LED is red.
Instead, this LED blinks as follows:
• Green for each GPS satellite being tracked;
• Pause, if at least one satellite has the energy potential more than 48 db*Hz,
red blink instead;
• Orange for each GLONASS satellite being tracked;
• Pause, if the receiver can estimate its navigation position, red blink if it
can't.
For example, if 8 GPS and 5 GLONASS satellites are being tracked, the STAT
LED repeatedly blinks 8 greens and 5 oranges between successive pauses or
reds.
