I GET A LOW PITCHED

HUM IN MY HEADSET

SPEAKER AND/OR MY

CALLERS COMPLAIN

THEY CAN HEAR HUM.

I HEAR THREE ‘BEEPS’

IN THE HEADSET.

PROBLEM

ITEMS TO CHECK

MY CALLERS SAY

THAT THEY CAN’T

HEAR ME AT ALL OR

THEY CAN’T HEAR

ME VERY WELL.

Make sure the microphone of your headset is

positioned in front or near your mouth. If you

are using a “noise-cancelling” headset, the

position of the microphone is very important.

You may need to adjust the “Outgoing

Volume”. See “Adjusting Headset Outgoing

Volume” on page 10).

Confirm that the Telephone/Amplifier

Compatibility Switch is in the correct setting

for your phone (see "Set the Telephone/Amplifier

Compatibility Switch” on page 5). You may

want to try moving the switch through all of

the positions until your caller hears you clear-

ly. Experimenting with various switch settings

will not harm the amplifier or your telephone.

Try moving the Telephone/Amplifier Compatibility

Switch through all of the positions until the

hum disappears. Experimenting with various

switch settings will not harm the amplifier or

your telephone.

If you are using batteries to power the Vista

Amplifier, the three ‘beeps’ tell you that the

batteries are low and need to be replaced.

See “Install Batteries”on page 2.
