ear tip and medium ear loop. You can also configure your headset for your
left ear, install a different sized ear tip and ear loop, or install the headband.

NOTE You will feel resistance when rotating the ear loop down; this is normal.
2 Remove the ear loop from the headset.
3 To wear the headset on the right ear but with a different sized ear loop or ear tip, select the size you
want and reinstall in reverse order as shown. Make sure the notch in the ear tip faces the microphone.
Left ear loop assembly

the headset. Make sure the ear loop is flat against the headset and rotate the ear loop up 90SDgr.

Headband assembly
The headset can be rotated for wearing on the left or right ear.
NOTE Before installing the headband, remove the ear tip and ear loop from the headset.
1 Hold the headband so it is aligned to receive the headset as shown and insert the headset into
the headband.
2 Rotate the headset up.
3 To optimise the position of the headset, push the headset in so the microphone is close to the
corner of your mouth.

Position your headset
When you wear the headset, the microphone should rest as close to your cheek as possible
without touching. The microphone can be adjusted inward by the pivoting earpiece to optimise
the position of the headset.
1 Slide the headset over and behind your ear and fit the ear tip into your ear.
2 Holding the base of the headset, push it in and back towards your ear to allow the pivoting
earpiece to bring the microphone close to your mouth. As the base of the headset moves
backwards, you will feel soft clicks until the microphone rests close to your cheek.

Base phone button and switches
1 Subscription button
The headset and base that came in the box are subscribed (connected) to each other. However,
if you wish to use a new headset or need to restore subscription to your current headset, the
units can be subscribed to each other by the following two methods.
Automatic secure subscription
With your system idle, docking a headset will automatically subscribe it to the base, making it
the primary headset. The power on/subscription LED will flash white during the subscription
process and become solid white when the new subscription is established.
Manual over-the-air subscription
1With your system idle and your headset undocked, press and hold the subscription button on
the base for three seconds. The power on/subscription light will flash white.
2 Press and hold the volume up button on the headset for three seconds until the headset LED
turns solid white. When the power on/subscription LED on the base becomes solid white, the
headset and base are subscribed to one another.
NOTE If the subscription process times out after two minutes or if the subscription process fails,
the subscription LED on the base will go dark for three seconds and then re-illuminate steadily to
indicate power is applied to the base. If this occurs, try to re-subscribe the headset again.
Ending subscription
If the base is in subscription mode and you want to stop the base from searching for a headset,
press the subscription button again. The subscription LED on the base will go dark for three
seconds and then re-illuminate steadily to indicate power is applied to the base.
