7. Operation
Once the ATLAS PT is turned on by pressing the power button, the internal GPS will
begin to try to lock onto the GPS satellites.
The Status LEDs on the front of the RV-M7 will begin to blink orange.
After 10 to 60 seconds, depending upon the satellite strength, orange blinking will stop.
This indicates the internal GPS receiver is locked onto GPS satellite signals, and has a
position fix.
The ATLAS PT will only transmit if it has GPS lock. If the GPS antenna is broken or
obscured, the unit will not report position or status.
When it is locked to GPS, the unit will transmit its position and status at the interval
programmed into the TXRATE parameter.
7.1 Battery Life
The ATLAS PT can report its charge percentage which can be used to determine how
much life is left in the battery. Set TXBATPCT to 1 to have battery charge percentage
transmitted in the PRAVE messages instead of the voltage. Use the ATBC command to
read the percentage manually.
If an external battery is connected, the reported percentage will be the charge
percentage of the total capacity of all batteries (internal and external taken together).
