							Link to cell feature
T o 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:
R You 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.
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. Pairing a cellular phone

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