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 6position 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.

B.1.5.2 Transmission/Microphone Connection Pairing

The

Microphone Selector (6)

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.

Dial a telephone number. If the person on the other side cannot hear your voice, then select the

Microphone Selector (6)

one by one until the person can hear your voice clearly. Repeat this step if necessary.
