USING THE PHONE
Note: When the tone (treble), earpiece volume and
sending levels are set to the maximum, whistling
may occur. If whistling occurs the sending level
settings should be decreased (switch (19)).
When the switch (24) located behind the phone
is ON, the extra-receiving and tone functions are
automatically activated each time you use the
phone.When the switch is switched OFF, you
will need to activate the function by pressing the
button
(20). Tone and volume adjustment
(15dB to 30dB) is only activated when the button
is set to ON. When this button is set to OFF only
the volume can be adjusted from 0dB to 15dB.
