SWR CAL CONTROL :
This SWR CAL control allows the user to
calibrate the SWR meter.
7.
CLARIFY CONTROL :
Allows tuning of the receive frequency above
or below the channel frequency.
8.
CHANNEL SELECTOR :
This control is used to select a desired
transmit and receive channel.
9.
FRONT PANEL METER :
The Front Panel Meter allows the user to
monitor signal strength, RF output power and SWR level.
10.
S-RF/CAL/SWR SWITCH :
In the S-RF position, the meter will
indicate the strength of the signal being received, as well as the relative
RF output of transmission. When calibrating the SWR meter, you need to
put this switch in the CAL position. To use the meter to measure the
standing wave ratio, turn the switch to the SWR position.
11.
ANL/OFF SWITCH :
In the ANL position, the Automatic Noise
Limiter (ANL) in the audio circuits is activated.
12.
NB/OFF SWITCH :
In the NB position, the Noise Blanker (NB) is
activated. The NB is very effective in eliminating repetitive impulse
noise such as ignition interference.
13.
PA/CB SWITCH :
Select the mode of operation. In the PA position, the
radio acts as public address amplifier. Your voice will come out of the
speaker that is plugged into the PA. SP. jack on the rear panel. The radio
does not operate when you are in the PA mode. In the CB position, the
PA function is disabled and the radio will transmit and receive on the
speaker that is connected.
14.
TONE SWITCH HI/LO :
This switch changes tone quality in receive
only. In LO position, bass is increased and in HI position, treble is
increased.
15.
CH9/NORMAL SWITCH :
Channel 9 switch is used for instant
selection of an emergency channel.
16.
TX/RX LED :
The red LED indicates the unit is in the transmit mode.
The green LED indicates the unit is in the receive mode.
17.
ANT LED :
This LED lights orange when your SWR is higher than
about 3:1. This is not an exact indicator of 3:1 SWR, but it is an
indication that you should check your SWR reading.
18.
CHANNEL DISPLAY :
The channel display indicates the current
selected channel.
19.
ILLUMINATION :
Face plate will illuminate when turn on the radio.
REAR PANEL
1.
ANTENNA :
This jack accepts 50 ohms coaxial cable with a PL-259
type plug.
2.
DC POWER :
This accepts 13.8V DC power cable with built-in fuse.
The power cord provided with the radio has a black and red wire. The
black goes to negative and red goes to positive.
3.
PA SP. :
This jack is for PA operation. Before operating, you must first
connect a PA speaker (8 ohms, 4W) to this jack.
4.
EXT. SP :
This jack accepts 4 to 8 ohms, 5 watts external speaker.
When the external speaker is connected to this jack, the built-in speaker
will be disabled.
