About internal and external ring detectors
Adjust the sensitivity level
The default setting of the ring detector
works with most corded telephones.
However, the ring detector might 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 increase the sensitivity.
Turn the SENSOR ADJ knob
counterclockwise 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.
