Operation

Volume Control

The Handset volume control located on the front of the phone enables 
you to adjust the receiver volume on the handset. 
Persons requiring a louder earpiece for comfortable operation can use 
the earpiece boost function. The receiver volume can be boosted up to 
24dB during a conversation. Press the 

BOOST button, and the Boost LED

will light.
You can turn OFF the BOOST by pressing the 

BOOST button at anytime 

during your conversation, the BOOST LED will turn off and the volume will
return to normal level. When you replace the handset on the cradle, the 
boost volume will be reset to normal.
Note: If you do not need this additional amplification you do not need to 
press the 

BOOST Button.

Warning:
Setting your earpiece volume too high can damage your hearing!!! 

You can use the TONE slide switch to adjust high frequency sounds. 
Words are clearer and easier to understand. Note: The tone
adjustment function will not work if the receiver volume is set to the 
minimum level.

Hearing Aid Compatibility

This unit is compatible with most inductively coupled hearing aids on 
the market. However due to the wide range of hearing aids available we 
cannot guarantee that the unit will function error free with every model.
