							Link to cell feature
T
o use this feature, you must first
register and connect your cellular
phones to the base unit (page 19).
Your cellular phones must be Bluetooth
wireless technology compatible with this
product.
This feature allows you to:
– make or answer cellular calls using your home phone (handset or base
unit) with better reception.
– maximize the benefits of cellular services (such as free night and
weekend calls, or cellular to cellular
call plans) by utilizing unused peak
minutes with your home phone.
– conserve the battery power of your cellular phone while the unit is on a
cellular call. (We recommend
charging your cellular phone during
the cellular call as your cellular phone
battery is being consumed.)
Important:
R Up to 2 cellular phones can be
registered. However, only one
Bluetooth device (cellular phone or
headset) can be connected to the
base unit at a time.
R Locate your cellular phone near the
base unit. If the cellular phone is too
close to the base unit during a cellular
call, you may hear noise. For best
performance, we recommend placing
the cellular phone between 0.6 m to 3
m (2 feet to 10 feet) away from the
base unit.
