Setting the volume / tone
Set the volume control to low before picking up the telephone and adjust the

alter the tone by amplifying high and low tones.
Furthermore the output volume can be doubled by pressing the amplifier
booster button. The set volume is increased when the amplifier button is
pressed down and held. The button must be disengaged while talking.
