designed to provide many years of enjoyment. To ensure that your investment is enjoyed to
its fullest extend please take a few moments and thoroughly read this manual.
Important: In Europe there are several regulations regarding CB use in the various
countries. The MAGNUM MULTI covers 11 of the most used regulations in Europe.
Please make sure that this radio is operated according to the national regulations of the
country you stay in.
LIMITED WARRANTY
Magnum Europe warrants this product to be free of defects for a period of 2 years from the

INSTALLATION
1. Contents
Unpack and inspect your MAGNUM MULTI for missing or damaged components. Packing
includes:
1. Magnum MULTI transceiver
1. Microphone
1. Microphone hanger
1. Power cord
1. Mounting bracket + screws
1. User Manual English
2. Microphone Hanger
The microphone hanger may be attached to the side of the transceiver or any other
convenient location. Locate the mounting holes on either side of the transceiver. Use the
provided screws to attach the microphone hanger either vertically or horizontally to the side
of the transceiver.
Or mount the microphone hanger to an other convenient location near your transceiver.
3. Mounting Bracket
When attaching the MAGNUM MULTI mounting bracket to the vehicle, choose a location
that will provide easy access to all front panel controls. When selecting a mounting location,
make sure that there is ample space behind the unit for the cables. Do not pinch, or bend
sharply the power or antenna cables. Do no install this radio in any compartment that
restricts airflow and do not install in a location that interferes with the safe operation of the
vehicle.
4. Electrical Connections
The MAGNUM MULTI is designed to work on a 12-13.8Volt DC negative ground source.
The condition of the vehicle’s electrical system can affect operation. A low battery, worn
generator/alternator or a poor voltage regulator will seriously impair the performance of the
transceiver. Any of the above conditions could result in a high level of receiver noise
generation or a substantial loss of the transmitter’s RF output.
Make sure that all of these components of your vehicle’s electrical system are in good
condition prior to installing the transceiver.
CAUTION: Voltage exceeding 15VDC will damage the radio. Measure voltage at battery
terminals, with vehicle running, prior to installation.
Before making any electrical connections make sure the volume control/on-off is in the
“OFF” position. Connect the positive (+) red wire of the DC power cord to a positive 13.8
Volt source at the vehicle fuse block. If connected to the fuse block it is recommended that
a switched power source is used so that the power to the transceiver is disconnected when
5
Page 6
the vehicle is off. This will eliminate the possibility of the transceiver draining the vehicle’s
battery.
Connect the negative (-) black wire to a metal part of the vehicle’s frame, or chassis
ground. Make sure that this is a good ground connection.
The power cord may also be connected directly to a 12 Volt battery. Connecting directly to
the battery has several benefits. The first is to maximize RF output power.
Secondly the battery is a very large capacitor and will help to eliminate certain types of
ambient and vehicle noise. If connecting directly to the vehicle’s battery, additional power
cable may be required. On runs up to 2 meter use 0,75mm2 Use 1,5mm2 wire on longer
runs.
5. Antenna Connection
The transceiver will operate using any standard 50 Ohm ground-plane, vertical mobile
whip, long wire or similar antenna. The antenna should be rated at 50 Watts minimum. A
standard SO-239 type antenna connector is located on the rear panel of the MAGNUM
MULTI. Connection to the antenna is made using a PL-259 and coaxial cable (RG58A/U or
RG213).
A ground plane antenna provides greater coverage and is recommended for fixed stationto-mobile operation. For point-to-point fixed station operation a directional beam antenna
operates at greater distances even under adverse conditions. Not all national authorities
accept the use of beam antenna’s for CB use.
A non directional antenna should be used in a mobile installation; a vertical whip is best
suited for this purpose. The base loaded whip antenna normally provides effective
communications. For greater range and more reliable operation a full quarter wave whip
may be used. Either of these antennas uses the metal vehicle body as a ground plane.
Once the antenna is mounted on the vehicle, route the coaxial cable so that it is not next to
any power cables or vehicle cables. Connect the PL-259 to the antenna connector on the
rear panel of the MAGNUM MULTI.
Make sure that the cable does not interfere with the safe operation of the vehicle.
6. Vswr
Before you start using the radio it is important to determine the antenna system’s VSWR
(voltage standing wave ratio). You need a quality SWR bridge (meter) to accurately tune
your antenna system. First, make sure the SWR bridge is in good working order and is
calibrated. To ensure your radio is performing properly the VSWR should never exceed 1.5
to 1. Never transmit on any antenna system where the SWR exceeds 1.8 to 1. This will
stress the output stage and could destroy the RF transistors.
This type of misuse and
failure is not covered under warranty!
Measure the VSWR at the center of the operating band. Tune the antenna (according to
the antenna manufacturer’s tuning instructions) so that the VSWR is as close to 1 to 1 at
the center of the operating band.
6
Page 7

Next, measure the VSWR at the lowest and highest frequency of the operating band of the
transceiver. If the antenna has a wide enough frequency range and band-pass, the VSWR
readings should be below 1.5 to 1 across the entire operating band. If at the lower or upper
end of the transceiver operating frequency , the VSWR measures more than 1.5 to 1, it is
recommended that the antenna is re-tuned before operating on those frequencies.
If you are experiencing unusual VSWR readings check for the following possible problems:
1. Make sure that the antenna is installed properly and grounded.
2. Check all coaxial cable and connectors for defects and poor routing.
3. Went testing a vehicle installation, make sure that all vehicle doors are closed.
4. Do not test near or around large metal objects or buildings.
7. Ignition Noise
In certain vehicle installations, electrical noise or interference may be present in the receive
audio of the transceiver. Typically the vehicle’s ignition system or more specifically the
generator generates this noise. The MAGNUM MULTI is equipped with a noise blanker
circuit that is designed to eliminate most or all of this electrical noise.
In extreme cases, the noise blanker may not eliminate all the electrical noise. In such
cases, an alternator ignition noise filter can be used. The PLF-10C Filter Cord by Magnum
International is designed for use with the MAGNUM MULTI and is an effective way to
eliminate alternator and ignition noise problems.
