Trouble Shooting Jabra PRO 920
Changing the Channel on Your Jabra 920
Wireless Headset
Look at the back of your headset. The circular dial with letters
from A-G (but no F) on it, is what changes the frequency on
which the telephone works.
Most telephones get a clear dial tone on either channel A or G.
Cisco is B. If you don’t have a dial tone, and you have power and
your battery is fully charged, you have paired the unit to the
base and also checked it isn’t in mute, try changing slowly
through the channels until you hear a dial tone.
Using Mute
There are three buttons on your headset. To turn mute
on, press the middle button. It is slightly concave so you
can find it quickly. A red led will light up on the bottom
front of your headset base. To turn mute off press the
same button again.
Changing the Speaker Volume (speaker - the
voice you hear)
To change the speaker volume (this is the volume of the
person’s voice on the other end of the phone) – press the minus
(-) or plus (+) buttons on your headset. These are either side of
the mute button. You can do this while someone is speaking
and it won’t affect the conversation, except how loud their
voice is.
The circular dial with letters from
A-G (but no F) on it, is what
changes the frequency on which
the telephone works.
Use the minus button twice in one second for
mute, same action to turn mute off
