Description
Fields SMS, CALL, CAMERA, GPRS, BUZZER, OUT1, and OUT2 can be presented by 0–6 in
decimal string.
Operation codes GET, SET, ADD, and DEL can be presented by 0–3 in decimal string.
These characters are not case-sensitive.
Note: Ensure that an authorized phone number is set by using the A71 command or the
parameter configuration tool before the B99 command is used to set the SMS/CALL
event code. The tracker compares the authorized phone number issued by B99 with the
authorized phone number (excluding +86 characters) of the tracker. If the phone
numbers are the same, the new event code will be stored. If the phone numbers are
inconsistent, an error SMS will be sent.

Description
When the speed is
0
, no speed limit exists. That is, when the tracker receives a
command, the function takes effect immediately.
When the speed is a value ranging from 1 to 255 (unit: km/h), set the speed limit. When
the driving speed is lower than the speed limit, the function takes effect.
