2. On the Meitrack Manager interface, select Fall, set a contact's phone number to receive

SMS messages and answer phone calls in case of emergency, enable the alert function, and

set the alert buzzing time, alert detection sensitivity and motion judgement time after the

alert is generated. You are advised to set the three parameters to 10, 1, and 0 respectively.

Note:

1. To avoid misinformation, the device will detect the effectiveness of man down alerts. After

the device falls to the ground, if it detects any angle changes and no motion for more than

three seconds, it will send a voice warning (or vibrate and make sounds). In this way, users

can press any button of the device to clear the man down alert as required. If no button is

pressed after the vibration and sounds stop, a man down alert will be generated. (The voice

broadcasting function is enabled by default, so the device will not vibrate and make sounds.)

2. For details about the A29 command, see the MEITRACK SMS Protocol.

2.3.2 Data Usage Saving

With the function, users can select data to be uploaded. If the uploaded data occupies too much

data usage, users can set data uploading on Meitrack Manager to save data usage. For example,

if users want to upload the time, latitude, and longitude only, choose the Tracking tab page,

select the data to be uploaded, and click Set. This operation can save more than 80% of data

usage.
