OPERATING PROCEDURES
Maintaining Clear Communications
The performance of the Cord-Free Headset will vary depending upon
where the portable unit is placed on your body and the environment in
which the base and portable unit are used.
When first installing your Cord-Free Headset, try placing the base
unit in different locations to determine which location will provide
optimum performance. In addition, minimize communications inter-
ference by limiting the operation of other radio frequency devices
around the Cord-Free Headset. Such devices include other cordless
phones, wireless PBX systems and wireless local area networks.
When you turn on the Cord-Free Headset it automatically selects
a clear communications channel. If this channel starts to degrade,
press the CHNL key to select a new, clear channel from the 10
channels available.
If you move outside the range of the base unit, communications
between the units will become intermittent. To prevent this from hap-
pening, stay within the range of operation (approximately 20 feet).
If you try to turn on the portable unit when it is out of range or no
channels are available, the ON/OFF/MUTE indicator will turn on and
then off. Audible tones will also be heard.
Should you lose communications between the portable and base
units, place the portable unit back in the cradle of the base unit.
Once a beep is heard through the headpiece (approximately 2
seconds), a common security code will be established and you
may resume using the product.
Maintaining Secure Communications
Every time the portable unit is placed in the cradle of the base unit,
a unique sccurity code is established between the two units (i.e. one
of 65,000 codes). Once this code is established, other portable units
will be unable to make or receive calls from this same base unit.
Using the PAGE Key
To page a headset user or locate the portable unit,
you may use the PAGE key on the base unit. For Page
to work, the ringer on the portable unit must be set to
the On position.
To send a quick paging signal, press and release
the PAGE key. The portable unit will ring once for
several seconds.
To send a sustained paging signal, press the PAGE
key twice in succession. The portable unit will ring
continuously for 25 seconds or until you press one
of the ON/OFF keys on the portable unit.
