BASE STATION OPERATION
(Operating from 120V AC House Current)
To operate your transceiver from your home or office, using the regulär
house current as the power source, you will require the DYNASCAN Model CA-
20 Power-Pak which has been specially designed for the purpose. It is
available as optional equipment from your dealer. It consists of a precision-built
AC-DC power Converter that delivers the required power for the operation of the
transceiver. The CA-20 operates from any 120-volt, 60 Hz power source. Simply
connect the red (+) and black (-) leads of the transceiver to the, corresponding
terminais of the CA-20.

------------------------------------
Do not attempt to operate. this transceiver by connecting directly to
120 volts AC.
When the CA-20 Power-Pak is used with the transceiver for base station
operation, any Citizens Band beam, dipole, ground plane or vertical antenna may
be used. A ground plane vertical antenna will provide the most uniform horizon
tal coverage.
