The device is used to increase the signal range between transmitters and receivers and can transmit signals from any type of transmitter.

1. The default setting is to transmit signals from all transmitters and receivers. The device will operate in this mode when it is turned on. There is no need to program or input any settings.
2. If you want to transmit signals from only selected transmitters, please follow these steps:
   1. There are four function keys located at the back of the device (Call, Initialize, Mode, and Register).
   2. Press the “Register” button for one second. When the “Register” light (the third LED from the left) turns on, activate the first transmitter. At this point, the “Register” light will start blinking slightly. (If the light does not blink, it means the button has already been registered.) Encode all transmitters one by one in this way. After registering all the buttons, press the “Register” button for one second until the light turns off. The process is complete.
   3. Press the “MODE” button for one second and stop when the “MODE” light (the second LED from the left) turns on. This indicates that the amplifier now transmits only the signals of the transmitters stored in its memory.
