Instructions
AConnecting the M22 to your telephone and headset
Unplug the handset coiled cable from the telephone base and plug it
into the port labelled with the handset symbol on the M22.
Insert the coiled cable from the M22 port labelled with the
telephone symbol into the handset cord port on your telephone.
To connect your headset, put the 2 halves of the Quick Disconnect™
(QD) connector together. Your headset and M22 are both supplied
with QD connectors. (See diagram).
Refer to your headset user guide for further information on your
headset.
NOTE The telephone must be disconnected from the network before
installing the M22. Your telephone may have a special socket labelled
headset; if this is the case do NOT connect the handset to the M22.
Please check your telephone user guide to find out how to set up headset
operation on your telephone.
BAdjusting the M22
The M22 has been designed to work with most telephones. The
following instructions will help you to set up your M22 with your
telephone. Most telephones will work with the switch set in position
5. If this does not work try the other positions.
Installing batteries
The batteries on your M22 may need to be installed before you can
use your headset. You should disconnect your telephone from the
network before doing this.
To install the batteries, remove the battery cover on the side of the
M22 by pressing on the grips and pushing down.
Put the batteries into the compartment as shown on the inside of
the battery compartment, and replace the cover.
en
The M22 has a low battery indicator which gives 3 beeps when you
begin a call. If you hear this then replace the batteries as soon as
possible.
Setting the 7-position slide switch
The M22 is supplied pre-set to position 5. Try out the product at this
setting and adjust if necessary. Remove the mini-screwdriver from the
base of the M22 by sliding it out of the bracket. Use the screwdriver to
set the switch to the correct position for your telephone.
Fitting and removing the switch cover
On the left of the M22 is a cover. To remove it, hold the M22 firmly
and put your thumbs on the cover grips. Press and slide the cover
downwards. This gives you access to the adjustments for the transmit
level and the 7-position switch.
Adjusting the transmit level
The transmit level is how loud or quiet your voice is heard by people
on the other end of the line.
The M22 can be adjusted to set the optimum transmit level. However,
you need to fully install your headset before you make this adjustment.
When you have completed your headset installation, put on your
headset and make a call to a colleague. Use the screwdriver to adjust
the dial until the ideal sound and tone levels are reached. Turn the dial
clockwise to increase the sound level, anti-clockwise to decrease. The
sound level should be the same as when you are using the handset.
Once you have set this, the dial only needs adjusting if you change
your telephone.
When you have finished making adjustments, replace the security
cover and the screwdriver for future use.
Making and taking calls with the M22
Some phones can be programmed to allocate a button on the
telephone for headset use. This allows you to take a call by simply

pressing this button. Please refer to your phone user guide for
further instructions. For other phones, please follow the instructions
below.
The M22 has 2 modes –
1. Handset 2. Headset
To use the headset the green square indicator should be
showing on the headset switch. Press the button to switch between
the two settings.
To make a short call using the handset, press the headset button
on the top of the M22 so that the green square indicator does not
appear. Pick up your handset, dial and make the call as normal.
To make a call while wearing the headset, first lift off the handset
from the cradle. You should now hear the dialling tone and you can
dial and make the call as normal.
To take a call while wearing the headset, lift the handset off the
cradle when the phone rings.
Volume control
The M22 has a receive volume control, so you can adjust the volume
of your callers voice. To change the volume rotate the wheel until the
sound is at a comfortable listening level.
Mute button
The M22 has a mute button so that you can still hear the caller, but
they cannot hear you, for example, if you need to speak to a colleague
during a call. To do this press the mute button so that you can see the
green square indicator. Press the button again when you want your
caller to hear you.
