Headset considerations
Test the headset with the telephone before using. In a noisy environment, an
amplified headset is an option. When the amplified headset is used, there are
two choices of volume control: the rocker control on the telephone and the
switch on the headset. The user should adjust the telephone volume before
adjusting the headset volume. To provide the best communication with the
least amount of distortion, the amplifier should have a higher setting than the
telephone volume control.
Handsfree Allowed Class of Service is required for the M3903 and M3904 in
order for the headset to function properly.
