Featuring the latest in FM and Phased-Locked-Loop circuitry for crystal-
clear communication and maintenance-free operation. The system allows
three-station operation and can be expanded with add-on units. Absolutely
no installation is required; just plug into any AC outlet and use. The system
is ideally suited for private homes (as a remote, audio “babysitter”), offices,
factories, restaurants, hospitals, stores and schools.
FEATURES:
• Wireless - absolutely no installation required. Just plug into any AC
outlet and talk
• FM PLL (Phased-Locked-Loop) circuitry-gives you excellent and
noise-free conversation
• 2-channel selector-for use up to 4 stations operation
• Built-in “beep” call-for alerting other station

Automatic voice activation puts the intercom in the transmit mode
when you start talking. Stop talking and it automatically switches to
the receiver mode. Allows”hands free” operation while talking. If
you prefer manual operation, touch the “call” or “talk” SENSOR
SWITCH. Revert back to “automatic” with a single touch. A built-in
squelch system automatically eliminates electrical noises to trans-
mit crisp, clear sound.
No installation required - plug into any 110-120V AC outlet, turn set
on and talk! Apleasing “BEEP” sound alerts listener at the other
end. Buy them individually or in pairs, and add as many as desired.
