range limit. When in headset mode a warning alert of two beeps will sound in the
headset shortly before you meet the range limit.
On hearing this alert, you should walk closer to the base unit to ensure call quality
is maintained.
If you remain out of range for more than 15 minutes, the system will drop the call
permanently. If using a Plantronics Handset Lifter, the handset will be replaced and
the call terminated.

remaining), an audible warning will be heard through the headset as a single beep
repeating every 10 seconds Soon after hearing this warning, you should recharge
the headset.
FAILURE TO ESTABLISH A LINK
When the talk button is pressed and the handset and base fail to make a connection,
a warning alert of three beeps will sound in the headset. This may occur because you
are out of range of the base.
