1. Unplug the handset cord from your telephone base. Insert this plug
into the jack at the top of the HA40 Handset Amplifier.
2. Connect the HA40 Handset Amplifier to your telephone base.
3. Pick up the handset. If there is a dial tone, you have installed the

Volume Control
Adjust the volume to the most comfortable listening level by moving
the volume control slide switch.
For tone control, move the Tone Selector switch right or left to
a position that allows you to hear clearly. This will give you the
optimum speech clarity so that you can distinguish similar sounds
such as "chair" and "share."
Automatic Power On/Off
The HA40 Handset Amplifier has a voice detection sensor for the
automatic POWER ON/OFF control. If the phone line remains
silent for more than 10-15 seconds (for instance, when you are on
"HOLD"), the amplifier will "fade out" and return to its Standby
mode to reduce power consumption and preserve the battery. As
soon as any voice or noise is detected, the Amplifier will turn "ON"
again.

Clarity Power Technology
TM
Ensures the user that high frequency sounds are amplified more than
the lower frequencies. Conversations will not only be louder, but
clearer and easier to understand.
Boost Button
Press and hold down the BOOST button for additional amplification
when listening. This also eliminates any background noise and
feedback by muting the microphone in your handset. You must
remember to release the button when you speak so that
the other party can hear you, then press and hold the
BOOST button again when they speak.
The BOOST button engages the amplifier and Clarity Power. The
BOOST button will automatically reset to OFF upon hang-up. The
BOOST button will need to be depressed with each phone call to
restore settings.
Boost LED
The BOOST LED will illuminate red when the Boost feature
is activated.
Battery Indicator
The battery indicator light comes on every time you lift your handset
to indicate that the battery level is okay. If the indicator light does
not come on, the battery needs to be replaced.
When the battery is drained, the handset will still be operable if you
move the volume control switch to the minimum position. While
at any other setting, the handset will not work when the battery is
drained.

Battery Life

The average battery life depends upon how you adjust the HA40
frequency level. For normal usage, an alkaline battery should last for
6 – 12 months.

Troubleshooting

The HA40 Handset Amplifier is designed for long and trouble free
operation. However, if any problem arises in using your telephone,
disconnect the Handset Amplifier from the telephone. Reconnect
the handset to the telephone. If the problem disappears, then your
Handset Amplifier needs to be repaired. If the problem does not go
away when you disconnect the Handset Amplifier, then the problem
lies in your telephone or in your telephone line. Notify your
telephone company of your problem or take your telephone to a
repair center.
