① The operator portion is placed on the workbench while the customer portion is placed at the window, and one end of the
connecting wire with a terminal is inserted into the corresponding interface of the operator board J5. The other end of the cable is
connected to J1 of the customer board. The wiring method is shown on Page 3.
② Connect both ends of the power supply cable to the J2 port of the operator side motherboard (as shown below), and then plug
the power adapter into the power supply. Be sure to observe polarity!!
③ After checking that the connection of each connection port is correct, turn on the power switch on the operator side, and make
sure the power indicator light is ON.
④ Adjust the volume adjustment knob(s) on the operator unit gradually from low to high to make the internal and external volume
suitable.
⑤ Speak into the microphone on the workbench, the voice is broadcast on the customer portion outside when the operator talks,
the indicator light displays a blue signal. Speak into the customer unit, and the sound will be broadcast to the operator portion of the
system.
⑥ The operator unit or customer unit can output analog audio signals for recording through the RECORD interface.
⑦ You can start a conversation immediately when you plug in the headset, and you need to wait about 30 seconds to switch the
gooseneck microphone when you unplug the headset.
NOTE: Under normal circumstances, it is not recommended that customers adjust the SIDE MIC ADJUST (R16, R49). If it must
be adjusted due to environmental factors, it should be fine-tuned to avoid self-excitation or howling or intermittent calls due to
excessive adjustment.
