B.1.5 Pairing the Amplifier to your Telephone
B.1.5.1 Telephone Configuration Switch
Different telephones have a different pin configuration, users have to pair
the amplifier to the telephone model before it can operate effectively. The
Telephone Configuration Switch (7)
at the side panel allows you to select
the proper setting so that the unit will work with your telephone base unit.
The switch has 6 positions, which are (1 - 2 - 3 - 4 - 5 - 6).
Wear the headset over your head and switch the
Headset/Handset
Application Switch
(17)
to the Headset position. Make sure to turn down
the volume adjustment to protect your ear. Now select in turn the 6-
position Configuration switch one by one until you can hear a clear dial tone.
If you receive a clear dial tone sound, then the receiving connection is
working. Note that there may be 2 matching settings, choose the clearer
setting or either one if both perform the same. There is at least one setting
which matches your telephone.
After pairing the receiving (speaker/incoming) connection, in some
telephones you will have to select the transmitting (microphone/outgoing)
connection as well.

Caution: Make sure you turn down the microphone volume (10) before each trial,
because different microphone settings varies greatly in sensitivity, if the
microphone volume is set too high when switched to a sensitive setting, the
speaker may SQUEAL, which can cause damage to the user's ear and the unit.
