AM/FM/CB RADIOS
The AM/FM/CB radio combines the AM/FM radio
with a 40 channel Citizen Band radio. The controls are
illustrated in figures 3V-6 and 3V-7.
CB Radio Controls
The CB radio controls (fig. 3V-6) are as follows.
• Volume Control—The volume control knob controls
On/Off and volume. Push in for treble/bass control.
• Channel Selector Knob—This ring can be turned to
select the desired CB channel. As the knob is turned
the channel indicator display will indicate which
channel has been selected.
•Radio Function Control—This three position switch
positioned to the left, places the radio in RADIO
mode, when centered, the radio is in STAND-BY
mode and when to the right it is in the CB mode.
•Stand-By Mode Switch—Permits listening to the
AM or FM broadcast band until receiving a CB call.
In the STAND-BY position, the radio automatically
receives CB transmission. The operator can also
transmit while in the STAND-BY mode or return to
radio listening by releasing the microphone transmit
button. When another CB call occurs, the radio will
receive the call. In the RADIO position, only AM or
FM broadcasts will be heard without CB inter
ruption. Calls cannot be transmitted in the RADIO
position. In the CB position, calls can be transmitted
but there will be no AM or FM reception.
• CB Gain Control—Controls the volume of CB recep
tion independent of the AM/FM volume control.
