Maintenance
1. Unplug the unit from the telephone and the AC charger from the power source before cleaning.

The custom battery supplied should last 2–3 years. When talk time decreases
significantly, you should replace the battery. Call Plantronics at (800) 544-4660

Troubleshooting
Problem Solution
Sound in handset is
distorted/hear echo in
handset.
• Reduce speaking volume by changing the speaking volume
major adjust switch setting. See page 16.
• Point microphone towards your chin.
• Listening volume too high on phone. If your phone has a
handset volume control, lower this until the distortion
disappears.
• If the distortion is still present, lower the listening volume
adjust button on the headset. If the distortion persists,
select another listening volume major adjust switch
setting. See page 15.
• Base is too close to computer or phone. See page 10 for
proper positioning.
• System needs to be reset. Perform system reset as
described on page 21.
I can hear too much
background conversation,
noise or sidetone.
Speaking volume is too high. Lower the speaking volume by
adjusting the speaking volume minor adjust buttons on the
base. If the volume is still too high, select another speaking
volume major adjust setting. See page 16.
People I talk to can hear a
buzz in the background.
• AC charger is plugged into a power strip. Plug the AC
charger into the wall directly.
• Picking up another radio frequency. Call the Avaya Headset
Helpdesk for an RF filter.
Battery talk time performance
is significantly degraded even
after a full recharge.
Battery is going bad. Replace the battery with a new
battery pack. See page 22.
The call is dropped. (Talk
indicator on the headset and
base will not be illuminated.)
Headset lost subscription. Try to reset the system. See
page 21. If this does not work, try the resubscription
procedure on page 21.
I hear static that does not
allow me to communicate.
• Link to headset is lost. Try to reestablish a link by pressing
the headset talk button.
• Unplug the AC charger from the base for 7 seconds, then
plug back in.
• Reset the whole system as described on page 21.
I hear beeps in the headset.
• One beep every 10 seconds is caused by a low battery
warning. Recharge battery by returning it to the base
charge cradle for one to three hours until charge light stays
lit or quits blinking.
• Two beeps is an out of range warning. Move closer to the base.
• Three rapid beeps every 15 seconds indicates your mute is
on. Press the mute control dial once to turn mute off.
• When an optional lifter is connected, three repetitive beeps
indicate a call is coming into the headset. Press the talk
button on the headset to answer the call.
Handset lifter is installed
but does not lift handset.
Be sure the handset lifter power cord is firmly pushed into
the handset lifter jack on the base.
My handset lifter operates
every time I remove or
replace my headset in the
base unit.
IntelliStand is enabled. To disable the handset lifter, move
the IntelliStand switch to position .
