Installing the Radio
Choose a convenient location for operation that does not interfere with driver 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. Ao, 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 vehicles electrical system. For best performance, it is strongly recommended that the red lead be taken
directly to the positive terminal on the vehicles battery and the black lead be connected to the nearest chassis ground. (Note:
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 chassisground, 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 connection causes 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.

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 B ohms impedance and be able to handle at least 4watts. When the external speaker is plugged in, the internal speaker is disconnected.
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.
ON/OFF VOLUME CONTROL: Turn clockwise to apply power to the
2.
radio and to set the desired listening level.
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.

NB/ANL SWITCH: In the NB/ANL position, the RF Noise Blanker and
17. 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.

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.
10 KHz SWITCH: in the 10 KHz position, the transmit and receive
frequency is shifted 10 KHz up.
