INSTALLING YOUR GALAXY DX98VHP

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. Also, provide a

good electrical grounding connection to the chassis of 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 connected directly to the positive terminal on

the vehicle’s battery and the black lead be connected directly to the negative

terminal on the battery. (Note, not connecting both leads direct to the battery may

cause performance problems) 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. It is a good safety

idea to install a second 50 amp fuse that would provide protection in case the red

wire was to “fray” or get pinched and short to the body of the vehicle, somewhere

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 circuits that 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, quarterwave

length antenna. Ifantenna height is a problem, you may use a shorter, loaded-type

whipantenna although you can expect some loss 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 SP.) 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 4 watts. When the externalspeaker 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.PROCEDURE TO  

RECEIVE AND TRANSMIT

A. MICROPHONE

The push-to-talk switch on the microphone controls the receiver and transmitter. Press

the switch and the transmitter will activate, release switch to receive. When transmitting,

hold the microphone two inches from your mouth and speak clearly in a normal voice.

This transceiver comes complete with a low impedance dynamic microphone.

B. PROCEDURE TO RECEIVE

1. Be sure that power source, microphone and antenna are connected to the proper

connectors before going to the next step.

2. Turn VOL knob clockwise to apply power to the radio.

3. Set the VOL for a comfortable listening level.

4. Set the MODE switch to the desired mode.

5. Listen to the background noise from the speaker. Turn the SQ knob slowly

clockwise until the noise just disappears. The SQ is now properly adjusted. The

receiver will remain quiet until a signal is actually received. Do not advance the

control too far or some of the weaker signals will not be heard.

6. Set the CHANNEL selector switch to the desired channel.

7. Adjust COARSE/FINE control to clarify the SSB signals or to optimize AM/FM

signals.

C. PROCEDURE TO TRANSMIT

1. Select the desired channel of operation.

2. Set the MIC GAIN control fully clockwise.

3. If the channel is clear, depress the push-to-talk switch on the microphone and speak

in a normal voice.
