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 detects the
telephone ringer correctly:
The STATUS light on the lifter flashes quickly when the
telephone rings.
The detector sends the ring tone to the headset earpiece.
Ring detector on/off
When the ring detector detects an incoming call, it sends a ring
tone to the headset earpiece.
Press the RING ON/OFF button on
the lifter to turn the ring detector on
or off. The STATUS light is blue when
the ring detector is turned on, and red
when the ring detector is turned off.
When the ring detector is turned off,
it does not send a ring tone to the
headset.
NOTE: When you are using the speakerphone
of your telephone, the ring detector may send
a ring tone to the headset. If you do not want
the headset to ring, press the RING ON/OFF
button to turn the ring detector off. After the call, you can press the
RING ON/OFF button again to turn the ring detector back on.
