GENERAL

PAGE

1. This equipment complies with Part 68 of the FCC rules. On the bottom of this equipment is a label
that contains, among other information, the FCC registration number and Ringer Equivalence Number
(REN) for this equipment. If requested, provide this information to your telephone company.
2. The REN is useful to determine the quantity of devices you may connect to your telephone line and
still have all of those devices ring when your number is called. In most, but not all areas, the sum of
the RENs of all devices should not exceed five (5.0). To be certain of the number of devices you may
connect to your line, as determined by the REN, you should call your local telephone company to
determine the maximum REN for your calling area.
3. If your answering machine causes harm to the telephone network, the telephone company may
discontinue your service temporarily. If possible, they will notify you in advance. But if advance notice
isn't practical, you will be notified as soon as possible. You will be advised of your right to file a
complaint with the FCC.
4. Your telephone company may make changes in its facilities, equipment, operations, or procedures
that could affect the proper operation of your equipment. If they do, you will be given advance notice
so as to give you an opportunity to maintain uninterrupted service.
5. If there is a problem with this unit, the telephone company may ask you to disconnect this equipment
from the network until the problem has been corrected or you are sure that the equipment is not
malfunctioning.
6. Repairs can only be made by the manufacturer or an authorized service agency. Unauthorized
repairs void registration and warranty. Contact seller or manufacturer for details of permissible userperformed routine repairs, and where and how to have other than routine repairs made.
7. This equipment may not be used on coin service provided by the telephone company. Connection to
party lines is subject to state tariffs. (Contact your state public utility commission or corporation
commission for information.)

A beep is heard each time the handset is returned to the base unit.
This is normal operation. The handset is updating the security code.
After several attempts the TC-520 will not operate properly.

LIMITED WARRANTY

PAGE

IMPORTANT!
SALES SLIP OR EVIDENCE OF PURCHASE DATE REQUIRED
This limited warranty gives you specific legal rights; you may also have other rights which vary
from state to state.
The limited warranty is extended only to the original consumer of a CASIO PHONEMATE
product and is valid only with respect to consumers within the United States of America and
Canada. Subject to the following conditions, should this product prove defective by reason of
improper workmanship of material:
During the period of one (1) year from the date of original purchase, CASIO PHONEMATE will
repair or, at its option, replace the product without charge for parts or labor. If CASIO
PHONEMATE elects to replace the product, such replacement may be accomplished with a
factory-reconditioned unit.
This limited warranty does not apply: (a) to any product damaged by accident, misuse, improper
line voltage, lightning, fire, water, or other acts of nature, (b) if the product is altered or repaired
by anyone other than CASIO PHONEMATE, INC. or one of its authorized warranty stations or if
the FCC-approved connector plugs are removed. This limited warranty does not cover tapes or
broken or marred cabinets.
Except to the extent prohibited by applicable law, all implied warranties made by CASIO
PHONEMATE in connection with this product are limited in duration to a period of one (1) year
from the date of original purchase, and no warranties, whether expressed or implied, shall apply
to this product after said period.
Should this product prove defective in workmanship or material, the consumer’s sole remedies
shall be such repair or replacement as is herein-above provided. Under no circumstances shall
CASIO PHONEMATE be liable for any loss or damage, direct, consequential, or incidental
arising out of the use of or inability to use this product.
Some states do not allow limitations on how long an implied warranty lasts or the exclusion or
limitation of incidental or consequential damages, so the above limitations or exclusion may not
apply to you.
In order to obtain warranty service, you must provide evidence of purchase date. For your convenience, keep the dealer’s dated bill of sale or delivery ticket as evidence of the purchase date.
To obtain the name of the authorized CASIO PHONEMATE service facility,
call CASIO PHONEMATE ’s HelpLine at
(410) 686-2885 or (310) 320-9810.
If you live in an area that is highly susceptible to electrical storms, you may want to purchase a
Lightning Arrestor. The Lightning Arrestor attaches to your answering machine and if lightning
causes a surge through your phone line, the arrestor will help suppress the surge of electricity
which may cause damage to your unit.
To purchase your Lightning Arrestor, use the attached Accessory Order Form or call CASIO
PHONEMATE ’s Parts Department toll free: 1-800-322-9995.

CLEANING
CLEANING
THE BASE UNIT
CAUTION: Play messages before cleaning
and then disconnect the TC-520 from the
power outlet.
To assure high performance, periodically
clean the tape heads and capstan whenever
you notice an accumulation of dust and redbrown oxide particles. Use a cotton swab
moistened with isopropyl alcohol. Be sure no
alcohol touches rubber parts, as it tends to dry
and eventually crack the rubber. Use a damp
cloth or sponge to clean the cabinet. A mild
soap, like dishwashing detergent, will help
remove grease or oil. Do not spray cleaners
directly onto the machine. Cleaners should
only be used on the plastic surfaces. If they
get into the mechanism or speaker, they may
damage the machine.

CLEANING
THE HANDSET
CAUTION: Disconnect the TC-520 from the
power outlet before cleaning.
Clean the battery charging contacts on the base
unit and the handset with a soft cloth once a
month. Clean the antenna, and the plastic
cabinet of the base unit and the handset, with a
soft cloth only. Do not use excess water or
cleaning liquid of any kind.

MOVING THE TC-520
To relocate the TC-520, unplug the AC ADAPTER from the wall outlet for no more than 3
minutes. CAUTION: If the AC ADAPTER PLUG is disconnected from the back of the TC-520, all
memory (time/day setting, autodial numbers, last number redial) will be erased.

SINGLE TAPE SYSTEM
The TC-520 is a single cassette answering machine. Your outgoing and incoming messages are
stored on one microcassette. With this design, it is normal operation for the tape to reset before
callers can leave a message. If you have several long messages on the tape, it could take a few
seconds for the tape to reposition itself and for the TC-520 to record new messages. The caller
will hear a continuous tone while the tape resets.

AUTO EXTENSION DISCONNECT
You can answer a call from any extension phone connected to the same line as the TC-520. Pick
up any extension phone after the TC-520 has answered the call. The unit will automatically stop
playing your outgoing message or recording a message. If it does not stop, quickly tap the hookswitch on the extension phone without disconnecting the caller.

CHANGING CHANNELS
After TALK is pressed, the TC-520 selects the best available channel. If you hear noise or
interference while using the TC-520, press CHANNEL on the handset to change channels.

IMPORTANT CORDLESS
TELEPHONE INFORMATION

GENERAL

PAGE

Interference Information
Cordless telephone equipment generates and receives radio waves and, if not installed and used properly, may pick
up interference. To prevent interference:
Avoid locations such as heating appliances, electrical equipment (e.g., fluorescent lamp, TV, radio,
refrigerator, computer), places subject to direct sunlight, excessive dust, moisture, vibration, etc.
Locate the base unit in a high place in the house (such as the second floor) in order to receive the most
effective communication range. Fully extend the base unit antenna.
Notice: This cordless telephone uses radio communications between the handset and the base unit,
and may not ensure privacy of communication. Other devices including other cordless telephones
may interfere with the operation of this cordless telephone or cause noise during operation. Cordless
telephones must not cause interference to any licensed radio service.

WARNING
To prevent fire or shock hazard, do not expose the set to rain or moisture.
To avoid electrical shock, do not open the cabinet. Refer servicing to qualified personnel only.

CAUTION
1. Use batteries only intended for recharging. Use only the following battery pack:
Nickel-Cadmium Rechargeable, 3.6 volts, 250-300 mAh.
2. Do not dispose of the battery(ies) in a fire. The cell may explode.
Check with local codes for special disposal instructions.
3. Do not open or mutilate the battery(ies.) Released electrolyte is corrosive
and may cause damage to the eyes or skin. It may be toxic if swallowed.
4. Exercise care when handling the battery(ies) in order not to short the
battery(ies) with conducting materials such as rings, bracelets, and keys.
Ni-Cd
The battery or conductor may overheat and cause burns.

CONTAINS: NICKEL-CADMIUM
RECHARGEABLE BATTERY.
MUST BE RECYCLED OR
DISPOSED OF PROPERLY.

Charge the Handset Batteries Before Using the Cordless Telephone
The batteries lose their charge during shipping and storage. Be sure to charge the batteries before you use the
TC-520 cordless telephone. Place the handset in the base unit. The CHARGING/LINE IN-USE INDICATOR will
light. Leave the handset in the base unit for 12-15 hours. (See page 14.)

Digital Security Code
The Digital Security Coding System automatically resets a new personal security code to one of over 256
combinations every time you return the TC-520 handset to the base unit. (Whenever the handset is returned to the
base unit you will hear a beep.) The security code prevents unauthorized use of your telephone line, false rings
and false dialing. (US. Patent No. 5,073,932)

Ultra Clear® Noise Reduction Circuit
The TC-520 is equipped with Ultra Clear® Noise Reduction Circuitry (Compander Circuit). It reduces background
noise—reception is superior to conventional cordless telephones.

25 Channels with Optimum Channel Memory (OCMTM )
The TC-520 has 25 channels with Optimum Channel Memory. Optimum Channel Memory provides fast and clear
channel selection. The scanning circuit scans all 25 channels in your neighborhood to find the best available
channel. Once it finds the clear channels it selects and remembers the three best ones. When you press “Talk” to
call out or receive a call, the unit automatically provides you with the best channel. Whenever you place the
handset in the base unit for 2 seconds or more, the unit updates its memory. Press CHANNEL if you wish to
change channels manually. (U.S. Patents 5,197,093 & 5,418,839)
