Sec. 95.669  External controls.

    (a) Only the following external transmitter controls, connections or 
devices will normally be permitted in a CB transmitter:
    (1) Primary power connection. (Circuitry or devices such as 
rectifiers, transformers, or inverters which provide the nominal rated 
transmitter primary supply voltage may be used without voiding the 
transmitter type acceptance.)
    (2) Microphone connection.
    (3) Antenna terminals.
    (4) Audio frequency power amplifier output connector and selector 
switch.
    (5) On-off switch for primary power to transmitter. This switch may 
be combined with receiver controls such as the receiver on-off switch 
and volume control.
    (6) Upper/lower sideband selector switch (for a transmitter that 
transmits emission type H3E, J3E or R3E).
    (7) Carrier level selector control (for a transmitter that transmits 
emission type H3E, J3E or R3E.) This control may be combined with the 
sideband selector switch.
    (8) Channel frequency selector switch.
    (9) Transmit/receive selector switch.
    (10) Meter(s) and selector switch(es) for monitoring transmitter 
performance.
    (11) Pilot lamp(s) or meter(s) to indicate the presence of RF output 
power or that the transmitter control circuits are activated to 
transmit.
    (b) The FCC may authorize additional controls, connections or 
devices after considering the functions to be performed by such 
additions.
