FCC LICENSE REQUIREMENT
Do not transmit with your CB unit without an FCC(Federal Com-
munication Commission) Class D Citizens Radio Service
License, or temporary permit.
Youmust applyfora license by mailinga completed FCC Form505to
the FCC, GETTYSBURG,PA. 17326.
At the time this User's Guide was published, no fee for Class D
Licenses was required. This is, of course, subject to change in the
future.
You may use Form 555-B as a temporary permit whileyour regular
Form505application is beingprocessedbythe FCC.
.
Transmittingwithouta license or temporary permit is illegal,but you
can listen to (or monitor) all channels without a license. You are
!
required to be familiar with and understand Part 95 of the FCC
Rules when transmitting.
General requirements for an FCC license are that you must be 18 or
over and a U.S. citizen. Anyone 12 or over in your household can
operate the CB as longas the FCCrules and regulationsare followed.
Your FCC station license willshow your call "letters" (or "sign").
Five or more units may be operated under a single FCC station
license. Ifyou plan to have more than fiveunits, specifyquantityon

SPECIFICATIONS
GENERAL
CHANNELS: AM-40 channels. PLL digital logic channel synthesizer
circuitry. 40 USB and 40 LSB channels.
POWER REQUIREMENT: Consumption - 34.5 watts. Current drain -
2.5 amps (Max at 12 watts PEP) at 13.8-volt DC.
POWER SUPPLY: 12 volts DC nominal (positive or negative ground),
or 120 volts AC
-
60 Hz.
SEMICONDUCTORS: Integrated circuits, transistors, FET (field
effect transistor), diodes, and 2 crystal filters
-
one in the AM IF and
one in SSB IF.
Crystal filters differ from LC or ceramic filters in that they are more
selective and reduce unwanted incoming signals.
