Ring detector installation

Adjust the sensitivity level

The ring detector sensitivity level is
designed to work with most corded
telephones. However, the ring detector
may need some adjustments to
recognize less common telephone ring
tones.
To adjust the ring detector sensitivity
while the telephone is ringing:
• Turn the SENSOR ADJ knob
clockwise to the right to increase the
sensitivity.
• Turn the SENSOR ADJ knob
counterclockwise to the left to
decrease the sensitivity.
When the ring detector senses the
telephone ringer correctly:
• The STATUS light on the lifter flashes
quickly when the phone rings.
• The detector sends the call alert tone
to the headset earpiece.

Headset incoming alert tone

• The ring detector senses the
telephone ringing with an incoming
call and transmits a call alert tone to
the headset earpiece.
