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 telephone
equipment generates and receives radio waves and, if not installed and used properly, may pick up interference. To
prevent interference:

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-540 cordless telephone. Place the handset in the base unit. The CHARGING INDICATOR will light. Leave the
handset in the base unit for 12-15 hours. (See page 20.)
25 Channels with Optimum Channel Memory (OCM
TM
)
The TC-540 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)
