For example:
In UK, the country code is 0044, or +44 .
The user cell phone number is 3408888666 and has been assigned as the first user number, the SIM card number
in the panel is 3408888555 .
Problem 1: Relay is activated but the first user have not received the SMS alert .
Solution: When you set the first number, you should add the country code in front of the 3408888666. Then it
means setup 00443408888666 instead of the 3408888666 .
Problem 2: The first user number can receive the Relay action message from the G202, but the G202 can not
receive the commands from the first user number.
Solution: Please add country code to the SIM card number in the G202. The it means send SMS commands to
003408888555 to instead of 3408888555 .
Solution 3: When you use cell phone to dial another cell phone, what number it will be displayed then you can set
this displayed number as the dial numbers; when you use cell phone send SMS to another cell phone, what
number it will be displayed then you can set the displayed number as the first user number, just use the 00 to

This command is useful in case you need to keep the relay closed (or button pressed) longer. The
default time is 0.5 seconds(500 ms). You can change it with the GOT command. The relay closed time
is twice as the number you set, E.g.: if you set pwd#GOT19#, means the relay closed 19/2=9.5
Seconds.
To check the value, you can use the command pwd#GOT? , the unit will reply the current value.
If you want to let the relay always closed until you call it next time, then you can set the time as 00,
the format is pwd#GOT00#, the relay will be always closed until next time call in. in this case, only
the authorized number can access it. The other unauthorized numbers can not access the unit. This is
very useful for remote switch on or switch off the electricity appliance or equipment or device for a
long time.
6.8 Check GSM signal quality
Check GSM signal quality. This command is useful to see the GSM network signal level of your GSM
Gate Opener. After you send the command, you can receive a SMS with signal quality in range 0 to 31
(if it is 0 we doubt it will never answer). To ensure to open the door successfully, we suggest to keep
the signal level above 12, or it will be better above 16. If it is below 12, please make sure you had
connected with an external GSM antenna, or take the device to a better open area where it will have a
better GSM signal.
