Preparation for Start-up
General Use Instructions
This AM FM SSB transceiver AE 5890 EU is a universal CB radio for 12V DC power supply. It can be connected in
vehicles, at high-performance 12V batteries, such as rechargeable lead batteries, and via a suitable 12V power
adaptor with at least 6A stabilized continuous current, at 230V mains power supply. The radio is, due to its
operating mode, which demands careful operation and repeated adjustment during operation, not everywhere
permitted to be used in vehicles while driving. Find out about the country's regulations, if you are permitted to
operate radios in the respective country while driving. In Germany the well-known "mobile phone prohibition"
applies only for mobile phones and not for two-way radios.
The radio is intended for intermitting operation with an average transmission time of approx. 10% of the On-time,
as usual for CB radios. This device is not intended for continuous transmission without regular receiving periods to
cool down. Avoid high humidity, extreme high and low temperatures, dust and direct sunlight. Open your radio only
if you have the necessary expertise, the correct tools and necessary measurement instruments.
On delivery the device has (according to the country of sale) the internationally usual CB radio range with 40
channels in all operating modes AM, FM, USB and LSB switchable. The Declaration of Conformity according to the
new European standard EN 300 433-2 applies only, if the device is not modified and used according to this user
manual. Any expansion of the frequency range to amateur radio and the use of other channels and operating
modes then permitted in the respective country is only permitted for licensed amateur radio operators an can have
legal consequences for unauthorized persons.
Power Connection
Connect your device with the supplied DC cable to a 12V DC circuit or a 12V power adaptor. Voltage fluctuations
between 11 Volts and 14 Volts for power adaptors and max. 15.6 Volts as for instance in vehicles, campers or
boats with rechargeable lead batteries, chargers or alternators, are permitted. The battery or the power adaptor
must be able to supply at least 6-8A stabilized. The power cord should not be extended. In vehicles always try to
connect directly to the battery terminals. This gives you the best protection against interferences from ignition and
alternator as well as the most stable operating voltage.
In case the in-line fuse in the DC cable blows, check the possible cause first (mostly reverse polarity and a
protective diode has kicked in) and replace the fuse only with the same type (10A, American glass fuse), never
short with silver paper or other methods!
Connect the red cable to the + terminal and the black cable to the – terminal of the power source.
The negative pole is on the radio casing, as for all modern vehicles. For boat installation insulation of the radio and
galvanic insulation of the aerial connectors can be necessary to protect against electrolyte or galvanic corrosion.
Safety Precautions and Vehicle Installation
There are no parts inside the device which must be accessible during operation. Leave the opening of the device to
experts. Do not open the casing without disconnecting the 12V power supply first. All work must be carried out de-
energized. For vehicle installation mount the radio with the supplied screws and the mounting bracket in a suitable
location in your vehicle. Ensure that the installation location cannot cause the risk of injuries for driver or
passengers and avoid the immediate vicinity of heater or A/C outlets.
Choice of Aerial
Vehicle Antenna
This radio is not to be used with temporary antennas such as mini magnetic base antenna, window clip antenna or
adhesive window antenna, as often used for CB radios.
For reasons of electromagnetic compatibility in the interrelation with neighboring electronic components a high-
performance exterior vehicle antenna with antenna base earthed via the car body is necessary. When selecting the
antenna location keep as far away as possible from passengers and vehicle electronics. In the interest of
pedestrians on the sidewalk avoid for instance the right mudguard. Ensure proper ground connection of the
antenna base to ensure that no RF reaches the vehicle interior via sheath current.
Car manufacturers have the right, according to applicable EU directives, to stipulate antenna installation locations
and the maximum compatible transmission power for their vehicles. Observe these specifications under all
circumstances not to risk to forfeit the operating license for your vehicle. Information is available from the car
manufacturers. If in doubt, have the car manufacturer certify that no reservations against CB radio operation in
connection with the car electronics exist!
Even if the effects of "electric smog" are controversial, do not subject other persons, who might think of your hobby
being dangerous, to electro-magnetic fields. Observe a great distance to the antenna if you carry a pacemaker.
Observe the manufacturer's information with regard to safe distances.
