Sidetone Adjustment
The SS-1002, SS-2002, and SS-2002RM use full-duplex audio (the same as conventional telephone lines) in which the talk
and listen audio are sent and received on the same wires. Thus, when you talk, you also here your own voice back as with a
telephone. If you are using the built-in speaker for listening and a either a panel microphone or handheld microphone for
talkback, you could experience unwanted feedback since the microphone may pick up your returned voice audio from the
speaker and re-amplify it. This could also happen if you are using a headset or headphones with open-ear style earmuffs. On
the other hand, if you are using earmuffs that completely enclose the ears, the microphone is not likely to pick up the returned
audio. A certain amount of your own voice level is desirable to overcome the muffled sensation when talking. The sidetone
adjustment is different for these different operating conditions:
If you are suing the speaker with a panel microphone, or if you are using an open-ear style headset or headphones,
adjust sidetone as follows:
1. SS-2002 & SS-2002RM only: activate channel 1 as described in the operating instructions.
2. Activate talk and listen as described in the operating instructions
3. Slowly increase the volume to maximum while talking into the microphone.
4. Using a small flat-bladed screwdriver, adjust the channel 1 sidetone trimmer to minimize your voice level in the head-
phones.
5. SS-2002 & SS-2002RM only: activate channel 2 and repeat the above steps to adjust the channel 2 sidetone.
6. Install the intercom station mounting screws after completing the adjustments. The station is now ready for use.
If you are using headphones that completely enclose the ears, adjust sidetone as follows:
1. SS-2002 & SS-2002RM only: activate channel 1 as described in the operating instructions.
2. Activate talk and listen as described in the operating instructions.
3. Set the volume control to the normal listening level for intercom audio
4. While talking into the microphone, use a small flat-bladed screwdriver to adjust the channel 1 sidetone trimmer so that you
can hear your own voice in the headphones at an acceptable level.
5. SS-2002 & SS-2002RM only: activate channel 2 and repeat the above steps to adjust the channel 2 sidetone.
