READ THIS BEFORE INSTALLATION
Your Caller ID system conforms to federal regulations, and
you can connect it to most telephonelines. However, each de-
vice that you connect to the phone line draws power from the
phone line. We refer to this power draw as the device’s
ringer
equivalence number
, or REN. The REN is shown on the bot-
tom of your system.
If you are using more than one phone or other device on the
line, add up all the RENs. If the total is more than five, your
phone might not ring. In rural areas, a total REN of three
might impair ringer operation. If ringer operation is impaired,
remove a device from the line.
FCC STATEMENT
Your system complies with Part 68 of FCC Rules . You must,
upon request, provide the FCC Registration Number and the
REN to your phone company. These numbers are on the label
on the bottom of the system.
Note: You must not connect your system to:
• Coin-operated systems
• Party-line systems
• Most electronic key telephone systems

PREPARATION
INSTALLING BATTERIES
Your system uses two AAA batteries to maintain information
in memory during power failures. For the longest operation
and best performance, we recommend you use alkaline bat-
teries such as RadioShack Cat. No. 23-555.
Cautions:
• Use only fresh batteries of the recommended size and
type.
• Do not mix old and new batteries, different types of bat-
teries (standard, alkaline, or rechargeable), or recharge-
able batteries of different capacities.
• When you replace the batteries, have fresh batteries on
hand before you begin. You must install fresh batteries
immediately after removing the old batteries; otherwise,
you might lose the information stored in the system.
• When you replace the batteries, do not press any but-
tons on the system after you remove the old batteries.
Doing so might erase all stored information from the sys-
tem.
• Never leave dead or weak batteries in the system. Bat-
teries can leak chemicals that can destroy electronic cir-
cuits.
• Dispose of old batteries promptly; do not bury or burn
them.

1. Make sure the system is unplugged from the telephone
line and AC power.
2. Use a Phillips screwdriver to remove the screw in the
battery compartment cover on the bottom of the system,
then remove the cover.
3. Insert fresh batteries into the compartment as indicated
by the polarity symbols (+ and –) marked inside the com-
partment.
4. Replace the cover and secure it with the screw.
Note: When appears on the display or the display dims,
replace the batteries.

CONNECTING THE AC ADAPTER
The AC adapter must be connected for the System 420 to op-
erate.
Note: You must also keep batteries in the system to protect
the information stored in memory during power failures.
Cautions:
• You must use an AC adapter that supplies 9 volts DC
and at least 50 milliamps. Its center tip must be set to
negative, and its plug must correctly fit the system’s DC
9V jack. The supplied adapter meets these specifica-
tions. Using an adapter that does not meet these specifi-
cations could damage the system or the adapter.
• Always connect the AC adapter to the system before you
plug it into the AC outlet, and unplug the adapter from
the AC outlet before you unplug it from the system.
Follow these steps to connect the supplied AC adapter.
