VOLUME AND TONE
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 according 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.
A
mplification over ride switch
In order to override the standard setting i.e.
AMPLI switched off, turn the amplification over ride
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
amplification over ride switch is ON, the extra receiveing 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 amplification override by pressing the
AMPLI button.)
OFF: When the switch is switched OFF, you will need to activate the function 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.
Handset Amplifier
In both cases, you can also boost the reception volume by an extra 12 dB by holding down the
handset amplifier button located on the handset.
Note: The button must be released while talking or it will act as a mute button
.
Caution: Exposure to high amplification levels to people without hearing loss may cause
damage to hearing.
