Sending Level Adjustment
If your voice is quiet or the person you have called has difficulty hearing, 
you can increase the sending level volume with the switch located on the 
right side. You can also decrease the sending volume if required. There are 
three levels, Min, Normal and Max (outgoing volume up to 12dB)
Receiving Volume and Tone Adjustment
You can increase the receiving volume and adjust the receiving tone ac-
cording to your own hearing requirements. The AMPLI button 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 to the left of 
the button is lit. Use the TONE and VOLUME slider buttons to adjust the 
level according to your own hearing requirements. When AMPLI is on, the 
receiving volume adjustment is 15- 30dB. The tone control allows you to 
either boost low or high frequency range. When AMPLI is off, the receiving 
volume adjustment is 0 - 15dB. The tone control cannot be used.
When the call is finished, the telephone will reset to standard mode i.e. 
AMPLI turned off.
Extra Volume Adjustment Switch
In order to override the standard setting i.e. AMPLI switched off, turn the 
extra volume adjustment switch, located on the rear panel of the telephone, 
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 AMPLI button. (during any call, you can temporarily switch off 
and on the extra volume override by pressing the AMPLI button.)
OFF: When the switch is switched OFF, you will need to activate the func-
tion by pressing the AMPLI 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 amplification setting.
