Turn on:
When the device is off, press the Power button for 3 seconds to turn
on the device. When the device is on, GPS will do cold start to locate its position
for the first time with the green GPS LED on. If location is fixed, the LED will be
blinking. If the location is not fixed in 3 minutes, the GPS function goes sleep
mode for 30 minutes before its next trial. It is suggested that you stay at outer
place or near the window where it can receive the better GPS signal when you
turn on the device.
NOTICE
: If it did not finish the successful fix after turned on, it may be difficult
to get fixed in the weak signal area or on the move.
After it is turned on or received the report command, TR-150 starts the GPS
fixing process. User can define the maximum time allowable for this GPS fixing
process. If TR-150 finishes the GPS fixing within the time, it returns location data,
and then close GPS. If TR-150 can not finish the GPS fixing within the time, it
returns previous location data, and then close GPS.
