15) CH 9/19:
Channel 9/19 is automatically selected.
16) ANL/NB:
Noise Blanker/ Automatic Noise Limiter. These filters allow the reduction of
back ground noise, and some reception interferences.
17) S/RF - SWR -CAL:
In the S/RF position, the meter swings proportionally to the strengh of the
received signal. When transmitting, the meter indicates relative RF output
power. In the "CAL" position, the SWR meter can be calibrated by adjusting
the "SWR CAL" control. When in the SWR position, the standing wave ratio is
measured.
18) 6-PIN MICROPHONE PLUG:
This plug is situated on the front panel, thereby making it easier to set the
equipment into the dashboard. See the cabling diagram on page 46.
19) PTT (push to talk):
Depress this knob to transmit a message and release to listen to an incoming
communication.
A) DC-POWER TERMINAL (13,2 V)
B) ANTENNA CONNECTOR (SO-239)
C) EXTERNAL S-METER JACK (Ø 2,5 mm)
D) EXTERNAL SPEAKER JACK (8 Ω, Ω, Ω, Ω, Ω, Ø 3,5 mm)
