Preparation

7. Press and lift out the handset holder, turn it upside 

down so its tabbed edge faces up, then slide it back 
down into its slot.

Note: To mount the phone directly on a wall, you need 
two screws (not supplied) with heads that fit into the 
keyhole slots on the bracket. Follow the steps under “On 
a Wall Plate or Wall” on Page 6 then apply these 
additional instructions for placement on a wall.

1. Drill two holes 3

15

/

16

 inches (100 mm) apart. Thread 

a screw into each hole, letting the heads extend 
about 

5

/

16

 inch (8 mm) from the wall.

2. Align the bracket’s keyhole slots with the mounting 

screws and slide the corded phone downward to 
secure it.

Plug one end of the supplied coiled cord into the modular 
jack on the corded phone’s side, then plug the other end 
into the modular jack on the corded handset.

Your corded phone requires 4 AAA batteries (not 
supplied) for Caller ID (CID) memory backup in case of 
power failure. For the best performance and longest life, 
we recommend RadioShack alkaline batteries.

• Use only fresh batteries of the required size and 

recommended type.

• Do not mix old and new batteries, different types of 

batteries (standard, alkaline, or rechargeable), or 
rechargeable batteries of different capacities.

Follow these steps to install the batteries.

1. Use a Phillips screwdriver to loosen the screw in the 

battery compartment on the bottom of the corded 
phone. Lift up the cover.

2. Install the batteries according to the polarity symbols 

(+ and –) marked inside.

3. Replace the cover and secure it with the screw.

When there is no battery installed or the batteries are 
low, 

 flashes on the display. Replace the batteries.

Warning: Dispose of old batteries promptly and properly. 
Do not burn or bury them.

Caution: If you do not plan to use the corded phone with 
batteries for a month, remove the batteries. Batteries can 
leak chemicals that can destroy electronic parts.

You can place the cordless phone’s charging cradle on a 
desk or table. Use the supplied 12V 200mA AC/DC 
adapter to power the charging cradle.

You must use a Class 2 power source that 
supplies 12V DC and delivers at least 200 
mA. Its center tip must be set to positive 

and its plug must fit the charging cradle’s 

 jack. The supplied adapter meets these 

specifications. Using an adapter that does not meet 
these specifications could damage the charging 
cradle or the adapter.

• Always connect the AC/DC adapter to the charging 

cradle before you connect it to AC power. When you 
finish, disconnect the adapter from AC power before 
you disconnect it from the charging cradle.

Plug the supplied AC/DC adapter’s barrel plug into the 
charging cradle’s 

 jack, then plug the 

adapter into a standard AC outlet.

The cordless handset comes with a rechargeable nickel-
cadmium battery pack. You must connect the battery 
pack and charge it for at least 12 hours before you use 
the phone for the first time.

1. Slide off the battery compartment cover.

2. Unfasten the retainer strap and lift the battery pack 

out of the compartment.

3. Plug the battery pack’s connector into the socket in 

the compartment (the connector fits only one way), 
then replace the battery pack and fasten the retainer 
strap.

4. Replace the cover.
