Receiving Volume and Tone Adjustment
You can increase the receiving volume and adjust the receiving tone ac-
cording to your own hearing requirements. The
AMPLIFY button on the
right side of the handset allows extra receiving and tone functions to be
activated during the conversation in an ad hoc fashion. When the function
is activated, the red light at the top of the handset is lit. Use the
TONE and
VOLUME slider buttons on the left side of the handset to adjust the level
according to your own hearing requirements. When AMPLIFY is on, the
receiving volume adjustment is 30- 50dB. The tone control allows you to
either boost low or high frequency range. When
AMPLIFY is off, the receiv-
ing volume adjustment is 0 - 30dB. The tone control cannot be used.
When the call is
fi nished, the telephone will reset to standard mode i.e.
AMPLIFY turned off.
Extra Volume Adjustment Switch
In order to override the standard setting i.e. AMPLIFY switched off, turn
the AUTO AMPLIFY switch, located in the battery compartment of the tele-
phone, to On. (Use the tip of a pencil or small screwdriver if necessary).
ON : When the switch is ON, the extra receiving volume and tone functions
are automatically activated each time you use the phone. You do not need
to use the
AMPLIFY button. (During any call, you can temporarily switch off
and on the extra volume override by pressing the AMPLIFY button.)
OFF : When the switch is switched OFF, you will need to activate the func-
tion by pressing the AMPLIFY button in order to get use of the extra volume
and tone functions.
This override is useful if the person using the telephone will always need
the ampli
fi cation setting.
Caution: Exposure to high ampli fi cation levels to people without
hearing loss may cause damage to hearing.
