Setting the Smart Sleep Mode – A73
SMS sending: 0000,A73,
Sleep level
SMS reply: IMEI,A73,OK
Description:
Sleep level = 0: The sleep mode is disabled (default).
Sleep level = 1: The device enters normal sleep mode. The 3G module always works, and the GPS module occasionally
enters sleep mode. The device works 25% longer in normal sleep mode than that in normal working mode. This mode
is not recommended for short interval tracking because it will affect the precision of travel routes.
Sleep level = 2: The device enters deep sleep mode. If no event (such as the SOS, button triggered, incoming calls, SMS
messages, or vibration) is triggered after five minutes, the GPS module will stop working and the 3G module will enter
sleep mode. Once an event is triggered, the GPS module and 3G module will be woken up. Then the above actions will
be cycled.
Note: In any condition, you can use an SMS command to disable the sleep mode, and then the device exits the sleep
mode and returns to the normal working mode.
Example:
SMS sending: 0000,A73,2
