First、The code comparison method：

1、Turn off the power of host and extension respectively, hold down the side key, and then turn on the power for 1-3 seconds,When the working indicator lights up and the red light flashes, press the "confirm" button on the host, and then hear the drip sound of the main and extension,The code is successful. Repeat the operation otherwise。

Second、（Backside of main engine ID）Expression method ：

1、Host ID number is as follows:02    03   08   13

main code spectrum month Date

2、According to site usage! Changes can be made.

Note: the number displayed on the standby display screen of the host computer is the main code (01-99). Users cannot change it at will; otherwise, the extension cannot connect with the host computer.

Third、change the main code (host standby display number) setting method:

1、Turn off main engine power → Hold on to the confirm button → Turn on the power and you can hear a beep → Release the confirm key and press the function key (set the main code“0X”The two Numbers)→ Then press "up" and "down"”To change the correct number, press the function key to exit.

2、After the main code changes need to be re-code: can be used normally.

Note: remind the operators of the installation and monitoring center in particular that this step cannot be operated at will at ordinary times, otherwise the code shall be reset if the call fails.

Fourth、 the way to change the volume:

1、After the host is powered on, hold down the function key to "set volume", such as：01 Press "up" and "down" to adjust the volume to the maximum04;After finishing, press the function key twice to exit.

Note: do not change the volume at will during use, so as not to misoperate and make the call unavailable.

Fifth、 methods to change frequency band:

1、After the host is powered on, hold down the function key twice to "set frequency band" state, such as:01 Press "up" and "down" to change the maximum frequency range to10;After finishing, press the function key to exit.

Note: do not change the frequency band arbitrarily during use, otherwise the main and extension calls will not work and the code setting needs to be reset; Remind the operators of the installation and monitoring center that this procedure is strictly prohibited in normal times.

Sixth、 the code and building number change method:

1、First the engine power is shut, hold down the side of the code key, and then open the power supply, keep 1 to 3 seconds, stay working indicator when the red light flashing, loosen your hand, to go to the host, and close the host power supply first, hold the host key code, open the power supply, after the red light flashing, loosen your hands, such as date input to the floor on a host computer house bugle call: building date and unit number, elevator; If 111, and then press the "confirm" button, after hearing the drip of the main and extension, the change will be successful. Otherwise, repeat this operation. (the code must be matched to the extension first, and it can be matched to the host within 20 seconds)

Note: the Numbers on the screen represent respectively from left to right: tower tower number, unit number and elevator number. The maximum number of elevator number is 4.
