ClearSounds Portable Telephone Amplifier Operation

Operation

You can adjust the volume level by using the Volume Control

Slide located on the top of the unit (left control). Pushing the slide

up increases the volume.

You can adjust the tone by using the Tone Control Switch lo-

cated on the top of the unit (right control). The Tone Control shapes

the sound by increasing the bass or the treble. The Tone Control

Switch has five (5) positions. Adjust the Tone Control until you find

a position that provides the clearest sound.

If you require additional amplification at any point in your conver-

sation, for IL40 only simply press & hold the Boost Button located on

the top of the unit. When the Boost Button is pressed, the micro-

phone in the handset is muted. This eliminates background noise

and feedback. Release the Boost Button when you want to speak.

The other party cannot hear you when the Boost Button is pressed.

Simply press & hold the Boost Button again, when you want

additional amplification.

The battery indicator light comes on each time you pick up the

handset to indicate the battery level is ok. If the indicator light does

not come on, the battery must be replaced.

Important: Before replacing the battery, make sure to

disconnect the IL30/IL40 from the telephone
