Link to cell feature
To use this feature, you must first pair and
connect your cellular phones to the base unit
(page 17).
Your cellular phones must have Bluetooth
wireless technology that is 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:
RYou may pair a maximum of 2 cellular
phones and 1 headset. However, the base
unit allows only one Bluetooth to be active
at a time.
RLocate 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.
Pairing a cellular phone
Important:
RFor more details and the list of compatible
cellular phones, please visit our Web site:

RBefore pairing a Bluetooth enabled cellular
phone to the base unit, make sure that no
other Bluetooth device such as a Bluetooth
headset is connected to your cellular phone.
