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.)
GENERAL
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.
The battery or conductor may overheat and cause burns.
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 (OCM
TM
)
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)
