2Product Overview
The T355 is a magnet GPS tracker developed by Meitrack Group and newly released in 2015. It is mainly used to track goods,
valuables, equipment, and other assets.
Two internal magnets make the tracker attached to the vehicle body and free of installation. If the tracker drops, a drop alarm
will be generated.
The unique rugged design of the shell ensures that the tracker is water resistant, dustproof, shockproof, and durable. The
standby time can last more than 365 days.

Note: The default password of the tracker is 0000. The password can be changed by using Meitrack Manager or SMS commands.
After the password is changed successfully by using an SMS command, only the authorized phone number can receive SMS
reports. The common format of an SMS command is: Password,Command,Parameter.
7.2 Smart Sleep –A73
This command is used to enable the sleep mode function, prolonging standby time to 240 hours. In this mode, the GPS Log,
scheduled tracking, and location tracking functions are disabled.
SMS text:
0000,A73,Sleep level
Send the text to the embedded SIM card phone number.
The MT90 automatically replies to the SMS: IMEI,A73,OK. It indicates that the sleep mode is set successfully.
To enable the GPS Log or scheduled tracking function, disable the sleep mode.
Note:
When the sleep level is 0(default value), the sleep mode is disabled.
When the sleep level is 1, the tracker enters the normal sleep mode. The GSM module always works, and the GPS module
occasionally enters the sleep mode. If the tracker is inactive (drop/incoming call/SMS/vibration) for 5 minutes, enable sleep
level 1. If the tracker is activated (drop/incoming call/SMS/vibration), sleep level 0 is enabled. In the device running mode,
sleep level 0 or 1 will be enabled alternatively.
The mode is not recommended for users who set the scheduled tracking at a short interval. This setting will affect tracking
integrity
When the sleep level is 2, the tracker enters the deep sleep mode. If the tracker is inactive (drop/incoming call/SMS/vibration)
for 5 minutes, the tracker enters deep sleep mode. In this mode, GPS and GSM modules can be enabled intelligently based on
vehicle driving status. This saves power.
In deep sleep mode, the tracker can be woken up when the tracker drops or vibrates. If the tracker is activated (drop/vibration),
sleep level 0 is enabled. In the device running mode, sleep level 0 or 2 will be enabled alternatively. In sleep mode, the
scheduled tracking, distance tracking, and GPS Log functions will be disabled.
