2Product Overview
The T355 is a magnetic 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.

3. Charge the battery.
To charge the battery, you can connect the device to the wall charger or a computer through the USB cable. When using
the device for the first time, you are advised to turn off the device and then charge the battery fully. When the battery
power is full, the LED indicator turns green.
Note: While charging, the device may heat up. This is normal, and this does not affect your device’s lifespan or
performance. If the battery power is low, it may affect positioning and data transmission. In this way, charge the battery
before use.
4. Start the device.
Turn the slide switch to the rightmost position, then press the drop switch 3 times within 5 seconds. The blue LED
indicator will blink 0.2s on and 0.2s off, indicating that the device has started. After power-on, wait for 15 seconds to allow
the device to complete the power-on self-test (POST) process.
Note: Ensure that the SIM card had properly installed before starting the device.
5. Stop the device.
Press the drop switch 3 times within 5s. The green LED indicator will blink 0.2s on and 0.2s off, indicating that the device
has stopped. After the device has stopped, wait for 5 seconds before restarting the device.
6. Install the device cover.
Place the back cover, and tighten the two screws by using the mini screwdriver.

8Quick Start Command
Before normal usage, common parameters must be set either by SMS command or by software.
8.1 Real-Time Tracking
This section describes how to query the current location of the T355, ensuring that the GPS is working normally.
Call the SIM card phone number that is used in the T355, and hang up after the dial tone rings 2-3 times.
Note: If an authorized phone number was set by SMS command A71, only this authorized phone number can call the SIM card
phone number and receive device's location information.
An SMS with a map link is received. Click the link to query the location.
SMS example:
Now,072714 02:48,V,16,23Km/h,61%,http://maps.google.com/maps?f=q&hl=en&q=22.540103,114.082329

If there is no valid GPS available, the tracker will reply the most recent valid position, along with GSM LBS information by AGPS.
If your mobile phone does not support HTTP, enter the latitude and longitude on Google Maps to query a location.
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.
8.2 Smart Sleep –A73
This command is used to enable the sleep mode function, prolonging standby time to 8760 hours. In this mode, the 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 device automatically replies to the SMS: IMEI,A73,OK. It indicates that the sleep mode is set successfully.
If the scheduled tracking function is required, disable the sleep mode.
Note:
When the sleep level is 0, the sleep mode is disabled.

MEITRACK T355 User Guide

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(default value), 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 way, a triggering event (drop/incoming
call/SMS/vibration) can wake the device up, and then the device enters working mode. In deep sleep mode, if there is no
triggering event (drop/incoming call/SMS/vibration) within 25 minutes, the device will automatically enter super power-saving
mode. In this mode, only a drop or vibration event can wake the device up. GPS and GSM modules can be enabled intelligently
based on vehicle driving status, which 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 and distance tracking functions will be disabled.

Note: If the tracker has not been attached to the vehicle for over 5 seconds, a drop alarm will be generated. After 5 minutes, if
no event (incoming call/SMS/vibration) is triggered, the device automatically enters the deep sleep mode. In any mode, the
deep sleep mode will be automatically enabled after the drop alarm is generated.
