Heartbeat for Telephone Management
With this function, you can store a service number to receive the “heartbeat calls” from the weatherproof telephone. Heartbeat call means you can set the
weatherproof telephone to call the service number every day or every 7 days. In this way you could know the weatherproof is not alive when you did not
receive the heartbeat call at the set time.
Store service number
E.g. Store a service number 135241532 to receive heartbeat call, 71 is the program parameter to store service number, the whole string is:
*#1235#71135241532#
Delete service number
71 also is the program parameter to delete service number, the only difference is no phone number followed the button number, the whole string is:
*#1235#71#
Set heartbeat call cycle
72 is the program parameter to set heartbeat call cycle time, E.g. To set the weatherproof telephone to call the service number every 2 days, the whole
string is: *#1235#722#
Note: The heartbeat call cycle time can be 0~9 days, default value is 0=disable the function.
Set heartbeat call time
73 is the program parameter to set heartbeat call time, E.g. To set the heartbeat call time to be 30 seconds, the whole string is: *#1235#7330#
Note: According to above settings, the explosion proof telephone will ring the service number 30 seconds every 2 days no matter the
call isanswered or not.
Default value=20 seconds. Call time rang can be 10~60 seconds.
