This equipment has been tested and found to comply with

the limits for a Class B digital device, pursuant to Part 15 of

the

FCC Rules

. These limits are designed to provide

reasonable protection against harmful interference in a

residential inst al lat ion . T his equipment generates, us es a nd

can radiate radio frequency energy and, if not installed and

used in accordance with the instructions, may cause

harmful interference to radio communications.

However, there is no guarantee that interference will not

occur in a particular installation. If this equipment does

cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and

on, the user is encouraged to try to correct the interference

by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and

receiver.

• Connect the equipment into an outlet on a circuit

different from that to which the receiver is connected.

• Consult your local Rad ioShack store or an ex perienced

radio/TV technician for help.

• If you cannot eliminate the interference, the FCC

requires that you stop using your intercoms.

Changes or modifications not expressly approved by

RadioShack may cau se int erfe r enc e and vo id the use r ’s

You can power your intercoms using four AA alkaline or

rechargeable nickel-cadmium (Ni-Cd)/nickel-metal hydride

(Ni-MH) batteries (not supplied). For the best performance

and longest life, we recommend RadioShack batteries.

Rý

1. Slide the battery compartment cover on the back of the

intercom in the direction of the arrow to remove it.

2. Slide

RECHARGE ON/OFF

OFF

(if you are installing

alkaline batteries) or

(if you are installing Ni-Cd or

Ni-MH rechargeable batteries).

3. Place the batteries in the compartment as indicated by

the polarity symbols (+ and –) marked inside.

4. Replace the cover.

Once each intercom has been turned on and you connect

its supplied AC adapter (see “Using AC Power”),

rechargeable batteries (if installed) are automatically

charged while the intercom is transmitting and standing by.

The battery life for recharg eable batterie s (Ni-MH, 15 00mA)

is about 37 hours.

When POWER/BATT LOW flashes or the intercoms stop

operating properly, replace or recharge the batteries.

You can power your intercoms using the supplied AC

adapters. You can also use the AC adapters to charge

rechargeable Ni-Cd or Ni-MH batteries you installed in the

intercoms.

"%#76+10"

You must use a Class

2 power source that

supplies regulated 9V

DC and delivers at least 400

mA. Its center tip must be set to

positive and its plug must fit the

intercom's DC 9V jack. Using an

adapter that does not meet

these specifications could

damage the intercoms or the

adapter.

• 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.

• If you do not plan to use the

intercoms with batteries for a

month or more, remove the

batteries. Batteries can leak

chemicals that can destroy

electronic parts.

• Always connect the AC adapters

to the intercoms before you

connect them to AC power.

When you finish, disconnect the

adapters from AC power before

you disconnect them from the

intercoms.

"9#40+0)

• Do not attempt to charge

alkaline batteries. Non-

rechargeable batteries can get

hot or explode if you try to

recharge them.

• Never install non-rechargeable

batteries when RECHARGE

ON/OFF is set to ON. Non-

rechargeable batteries can get

hot or explode if you try to

recharge them.

• Dispose of old batteries

promptly and properly. Do not

burn or bury them.

Preparation

1. Insert each AC adapter’s barrel plug into

DC 9V

on the

top of each intercom.

2. Plug the other end of the adapters into a standard AC

outlet.

Complete charging takes about 10 to 12 hours. Average

charging t ime varies, depending on capacity. Typically, Ni-

MH (1500 mA/H) batteries charge in about 12 hours. Ni-Cd

(700 mA/H) batteries charge in about 4 hours.

When charging is c omplete, unplug th e AC adapter from the

power source, then disconnect it from

DC 9V

The intercoms use radio frequencies called

channels

communicate with each other. Your intercoms have four

channels. The intercoms also use

sub-tones

within the

channels to help eliminate interference between intercoms,

even if someone is using another intercom set to the same

channel. Your intercoms have eight sub-tones.

The channels and sub-tones let you set each intercom so

they can:

• communicate with each other

• communicate with additional intercoms you purchase.

•

not

communicate with other intercoms

For example, if you have more than two intercoms installed

in your home, you can set them so the intercom you

installed at the front door communicates only with the

intercom you installed in the kitchen (so guests at the door

can announce themselves to somebody working in the

kitchen).

You must set any two intercoms to the same channel and

sub-tone for them to communicate with each other.

Each intercom has a group of DIP switches inside the

battery compartment. Use an object such as a straightened

paper clip to set the DIP switches.

1. On each intercom , slide the batt ery compa rtment c over

on the back of the intercom i n the directio n of the arro w

to remove it.

Important: The

EPA certified

RBRC

Battery

Recycling Seal on

the nickel-cadmium

(Ni-Cd) battery indicates

RadioShack is voluntarily

participating in an industry

program to collect and recycle

these batteries at the end of their

useful life, when taken out of

service in the United States or

Canada. The RBRC program

provides a convenient alternative

to placing used Ni-Cd batteries

into the trash or the municipal

waste stream, which may be illegal

in your area. Please call 1-800-

THE-SHACK (1-800-843-7422) for

information on Ni-Cd battery

recycling and disposal bans/

restrictions in your area.

RadioShack’s involvement in this

program is part of the company’s

commitment to preserving our

environment and conserving our

natural resources.
