CAUTION: To reduce the risk of fire or injury to persons or damage to

• Use four AA alkaline batteries (purchased separately).
• Do not dispose of the battery in a fire. Like other batteries of this type, it could
explode if burned. Check with local codes for special disposal instructions.
• Do not open or mutilate the battery. Released electrolyte is corrosive and may
cause damage to eyes or skin. It may be toxic if swallowed.
• Exercise care in handling batteries in order not to create a short circuit. Do not
allow conductive materials such as rings, bracelets, or keys to touch the battery.
The battery or conductor may overheat and cause harm.
• Do not disassemble your telephone. There are no user-serviceable parts
inside. Refer to qualified service personnel for servicing.

Getting started
Choose a central location close to a telephone jack. The telephone base can be
placed on a flat surface or mounted on a standard wall plate.
Avoid placing the telephone base too close to:
• Excessive heat sources.
• Excessive dust sources such as a workshop or garage.
• Excessive moisture.
• Extremely low temperature.
• Mechanical vibration or shock such as on top of the washing machine or
work bench.
Before you install
To use this product as a two-line telephone, you must have a two-line modular
wall jack or two separate one-line modular wall jacks. To use both lines of a
two-line telephone, your local telephone company must provide two telephone
numbers.
This product is designed to operate optimally with two telephone lines. If you
choose to install only one telephone line, the telephone will continue to oper-
ate normally as long as the unused line is not selected. For example, if you
press LINE 2 when there is only one line installed and that line is connected to
the L1 or L1/L2 jack, the telephone does not function properly. Simply press
LINE 1 and begin again.

Getting started
Battery installation
Before using the telephone, you should install four AA alkaline batteries
(purchased separately). You can use the telephone without batteries to dial
and receive calls. However, the line lights and the automatic redial feature will
not work, and the speakerphone and optional headset may not work properly
in all conditions. To use the speakerphone without batteries, you must press
and hold SPEAKER for one second.
NOTES:
• If you do not install batteries, you will hear a low battery warning tone every
time you lift the handset or press SPEAKER.
• Use disposable alkaline batteries only. Do not use rechargeable batteries.
CAUTION: Always unplug the line cord, before installing new batteries.
1. The wall mount bracket
should be flipped into
the downward position.
Place the telephone on
the wall mounting plate
and pull down until it is
held securely.
2. Push the tab as shown and
lift to remove the battery
cover. Insert four new AA
alkaline batteries (purchased
separately) following the
polarity markings in the
battery compartment.
3. Replace the
battery cover.
The following symptoms indicate that the batteries in your telephone are low and
need to be replaced, even though there is no low battery warning yet:
• The automatic redial feature does not work or is not working properly, or
• HEADSET cannot be used to make or answer calls.
If you experience either of these symptoms, try replacing the batteries following
the instructions above.
