UTRACK MVT600 User Guide Version 3.0

Authorize a phone number to make a silent call to the tracker. The tracker will answer the call automatically and

allows the caller to listen to what is happening around the tracker. There is no sound when the tracker is working.

Phone Number: 2 monitoring numbers at the most can be set, 16 characters per number.

If no preset phone number, it is empty (default).

If no phone number, but has “,”, the number related to this “,” is deleted.

Send command “0000, A72” to delete all phone numbers.

X=1, normal sleep. GSM module work, GPS module work by sleep mode intermittently. The device can work 25%

longer than no sleep mode. Note: this is not recommended for users who set “track by interval” or short time

interval, because it will affect the completeness of tracking.

X=2, deep sleep, the tracker will enter this mode after it is inactive or stationary (No SOS/any triggered by the

button/input/incoming calls/message/movement) for 5 minutes. GPS module stops working and GSM module

enters sleep mode. The tracker remains in this mode until it is activated by SOS/any triggered by the

button/input/incoming calls/message/movement. After that, it will repeat above processes.

Note: In any condition, the device will directly quit the sleep mode and back to normal working mode by SMS or

GPRS command to turn off the sleep mode.
