AP10 transmit and receive
✍ audio	level	adjustments
are	made	using	the
AP800. Nominal transmit			and

receive level for the AP10 is 0dBu.

Auto-adapt

If DIP switch 1 is off (down), call someone and continue to talk while the system gradually adapts over time. Once complete, the AP10 will be fully calibrated and ready for use. Press the Off button [E]. If the auto-disconnect feature is active, and the caller hangs up, the AP10 will disconnect upon sensing loop drop or call- progress tones, depending on the position of DIP switch 6.

Transmit level adjustment

Someone in the local room should speak into the microphone at a normal distance, in a normal voice. The party at the distant location should not speak during the transmit adjustment. Adjust the AP800 output that is connected to the AP10 Transmit input to 0dB. The AP10 Transmit LED [B] should illuminate solid green while the person is speaking and extinguish when the person stops.

Receive level adjustment

Someone in the distant location should speak into the microphone at a normal distance, in a normal voice; the local room should maintain silence. Adjust the AP800 input that is connected to the AP10 Receive output to 0dB. The AP10 Receive LED [C] should be solid green while the person is speaking and extinguish when the person stops.
