Chapter 2  Installation
 
  Installing the Radio
 
Choose a convenient location for operation that does not interfere with 
drive or passenger. This radio is supplied with a universal mounting 
bracket. When mounting the bracket and radio to your car, make sure it is 
mechanically strong. Also, provide a good electrical grounding 
connection to the chassis of the vehicle. Proceed as follows to install the 
radio.  
 1.  Locate a convenient area in your vehicle for the installation of the 
radio. Hold the mounting bracket with the radio in the location where the 
radio is to be installed. Make sure nothing will interfere with either the 
radio or the mounting bolts. Mark and then drill holes for the mounting 
bracket. 
2.  Most radio antennas come equipped with a PL-259 plug. Connect 
this plug to the ANT. Jack in the rear of the radio. 
3.  Extending from the rear of the radio is a fused red and black wire for 
the DC connections to the vehicle’s electrical system. For best 
performance, it is strongly recommended that the red lead be taken 
directly to the  positive terminal on the vehicle’s battery and the black lead 
be connected to the nearest chassis ground. (Note: This radio is 
designed for vehicles with negative ground systems.) 
 
Connections should  be made using appropriate “crimp on” lugs of a 
size large enough to make good contact with the bolt used to fasten to 
the battery and the chassis ground, It is a good safety idea to install a 
second fuse, in series with the red wire at the battery connection. This 
second fuse would provide protection in case the red wire was to “fray” 
or get pinched and short to the body of the vehicle, some where between 
the battery and the radio. 
High power radios such as this one require large DC current flow when 
in the TX mode. Poor power connections cause supply voltage drops that 
can substantially decrease the performance of your radio. A good DC 
connection is probably one of the most important things for getting the 
best transmitter performance and in some cases, least receiver noise.

 4.  Mount the microphone bracket near the radio in an easily accessible 
spot using the two screws provided.  Ignition Noise Interference
 
With weak signals, you may experience interference of the signal by 
background noise. This radio has NB and ANL controls which will help 
reduce background noise from sources such as your ignition system. 
However, background electrical noise may come from several sources 
and all noise may not be eliminated. With extremely weak signals, you 
can operate this radio with the engine turned off, which should improve 
reception. If the ignition noise level is too high to allow proper operation 
under most conditions, you should have your installation of the radio 
checked by a qualified technician.  Antenna 
This radio has a jack in the rear for a standard PL-259 antenna plug. If 
you are looking for the most range for your transmission, use a vertically 
polarized, quarter-wave length antenna. If antenna height is a problem, 
you may use a shorter, loaded-type whip antenna although you can 
expect some lost of transmission range. 
To improve performance, your antenna should be matched to your radio. 
Your antenna can be adjusted so that it matches your radio.  External Speaker 
The external speaker jack (EXT. SPK) on the rear panel is used for remote 
receiver monitoring. The external speaker should have 8 ohms impedance 
and be able to handle at least 4watts. When the external speaker is 
plugged in, the internal speaker is disconnected.  Public Address 
To use the Public Address (PA) function, first connect an external speaker 
to the PA. SP. Jack on the rear of the radio. See the above specifications 
for a proper external speaker. Keep the speaker away from the 
microphone to avoid acoustic feedback.

1. SQUELCH CONTROL: This control is used to control or eliminate 
receiver background noise in the absence of an incoming signal. For 
maximum receiver sensitivity, it is necessary that the control be 
adjusted only to the point where the receiver background noise is 
eliminated. Turn fully counterclockwise and then slowly clockwise 
until the receiver noise just disappears. Any signal to be received 
must now be slightly stronger than the average received noise. 
Further clockwise rotation will increase the threshold level that a 
signal must overcome in order to be heard. Only strong signals will 
be heard at a maximum clockwise squelch setting.  2. ON/OFF VOLUME CONTROL: Turn clockwise to apply power to the 
radio and to set the desired listening level.  3. RF GAIN CONTROL: This control is used to reduce the gain of the RF 
amplifier under strong signal conditions.  4. MIC GAIN CONTROL: Adjust the microphone gain in the transmit 
mode. This control is used to set the audio level of the microphone for 
maximum performance and clarity.

Operation
   (Continued)
 
  5. MODE SWITCH: This switch allows you to select one of three 
following operating modes: PA/FM/AM.  6. Fr. POOL: The Frequency Pool allow the user to select the desired 
segments of frequencies.  7. ECHO/TIME CONTROL: The ECHO control is used for echo effect. The 
TIME control is used to control the intervals of the echo sound.  8. RF POWER CONTROL: This control enables adjustment of RF power   
output continuously up to the rated output power.  9. TALKBACK/OFF CONTROL: Adjust this knob for desired volume of 
Talkback. This is used to monitor your own voice. Or example, you 
could use this feature to compare different microphones.  
 10. CHANNEL SELECTOR: This control is used to select a desired 
transmit and receive channel.   11. FRONT PANEL METER: The front panel meter allows the user to 
monitor signal strength and RF power out level.  12. TX/RX LED: The red LED indicates the radio is in the transmit mode. 
The green indicates the radio is in the receive mode.  13. FREQUENCY COUNTER: This frequency counter indicates the 
transmit frequency digitally.  14. DIM/BRT SWITCH: This switch is used to adjust the brightness of the 
meter and LED display for optimum intensity for day or nighttime 
driving.  15. HI/LOW TONE SWITCH: This switch changes tone quality in receive 
only. In LO position, bass is increased and in HI position, treble is 
increased.  16. S-RF/SWR SWITCH: In the S-RF position, the meter swings 
proportionally to the strength of the received signal. When transmitting, 
the meter indicates relative RF output power. When in the SWR

position, the Standing Wave Ratio (SWR) of your antenna. There are no 
adjustments because the SWR circuit this radio calibrates itself 
automatically. 
 17. NB/ANL SWITCH: In the NB/ANL position, the RF Noise Blanker and 
the automatic Noise Limiter in the audio circuits are also activated. The 
Noise Blanker is very effective in eliminating repetitive impulse noise 
such as ignition interference.  18. ROGER BEEP SWITCH: When this switch is placed in the ROGER 
BEEP position, the radio automatically transmits an audio tone at the 
end of your transmission. This indicates the end of your transmission 
so that people who are having trouble hearing you will know that you 
are done speaking. As a courtesy to others, use the Roger Beep only 
when  necessary.   19. +10KHz SWITCH: In the +10KHz position, the transmit and receive 
frequency is shifted 10KHz up.  20. CHANNEL DISPLAY: The channel display indicates the current 
selected channel.
