FEATURES
Your RadioShack Caller ID System 310 is the latest in telephone caller identification technology. If Caller ID service is
available in your area and you subscribe to it, the telephone
company sends the caller’s telephone number (and name, if
available in your area) and the time of the call between the first
and second rings. The module displays this information during
an incoming call to help you identify the caller before answering
so you can avoid unwanted calls. The module stores and displays up to 99 single Caller ID records (number only) or 50 multiple Caller ID recor ds (name and number).
Your module includes th ese features:
Large Liquid Crystal Display
— shows three full lines of caller
information to make it easy to see who is calling.

FCC INFORMATION
Your module has been designed to conform to federal regulations, and you can connect it to most telephone lines. However,
each module (and each device, such as a telephone or answering machine) that you connect to the telephone line draws power from the line. We refer to this power draw as the module’s
ringer equivalence number or REN. The REN is shown on the
bottom of the module.
If you use more than one telephone or other device on the line,
add up all the RENs. If the total is more than five, your telephones might not ring. In rur al areas, a total REN of three might
impair ringer operation. If ringer operation is impaired, remove a
device from the line.
Your module complies with Part 68 of
FCC Rules
. You must,
upon request, provide the Federal Communications Commission (FCC) registration number and the REN to your telephone
company. Both numbers are shown on the bottom of your module.

Note: You must not connect your module to:
• Coin-operated syst em s
• Party-line systems
• Most electronic key telephone systems
In the unlikely event that your module causes problems on the
telephone line, the telephone company no rmally attempts to notify you in advance. If advance notice is not practical, the telephone company notifies you as soon as possible and advises
you of your right to file a comp lai nt with the FCC.
The telephone company can also make changes to its lines,
equipment, operations, or proced ures that could affect the operation of this module. The telephone company normally notifies
you of these changes in advance, so you can take the necessary steps to prevent int erruption of your phone service.

This module complies with the limits for a Class B device as
specified in Part 15 of
FCC Rules
. These limits provide reasonable protection against radio and TV in terfe rence in a resid ential
area. However, your module might cause TV or radio interference even when it is operating prop erly.
To eliminate interference, you can try one or more of the following:
• Reorient or relocate the radio or TV receiving antenna
• Increase the distance between the module and the radio or
TV
• Use outlets on different electrical circuits for the module
and the radio or TV
Consult your local RadioShack store if the problem continues.

If your module is not performing as it should, check the connection to the telephone line. Calls are automatically switched and
routed through complex equipment, so you might occasionally
hear noise on the l ine. When a call is too noisy, hang up and redial the number. If you still have problems, immediately disconnect the module. If a telepho ne on the same line works proper ly,
the fault is in the module or its installation. If you are unable to
locate the problem, take your module to your local RadioShack
store for assistance.
