Most of all DECT cordless telephones in the market use the universal 2.5mm headset
port. (But not all DECT phones have a headset port, please check the user manual of
the DECT phone to see if the feature is available).
Locate the headset port of the DECT telephone (check your manual if needed), insert
the 2.5mm plug into the jack to complete connection.
2. Connecting headset to your DECT phone.
3. Understanding the In-line Controller.
Besides the Anti-radiation circuitry, the Microphone Mute Switch on the in-line
controller offers user quick privacy by muting the microphone pick-up. Slide the switch
to position (A) for muting and back to position (B) to go back to normal speaking mode.

Speaker Volume Control
C
The Speaker Volume Control (C) dial on the side of the inline controller allows user to
adjust the incoming volume. Increase volume by turning the dial towards the speaker
icon, and opposite direction to decrease volume.
Microphone Gain Switch
D
The Microphone Gain Switch (D) acts as a microphone pairing between the headset and
your DECT telephone. It is not designed to be a volume control, hence user is only
required to set this once.
Notice the three positions marked by different sizes of circle, the leftmost and smallest
circle indicates lowest microphone gain. Starting from the leftmost setting, make a call
and ask the person on the other side which setting has the optimum sensitivity level.
Caution: Make sure you switch to the leftmost position (E) before you adjust this
setting, because different DECT telephones have very different microphone
sensitivity, if the microphone gain is set too high, the headset speaker may
SQUEAL, which can cause damage to the user's ear and the headset.
