Important Note
Your Albrecht AE 4200 ASQ corresponds to the latest European CB standards. As a
unique feature, our standard version has a software country switching which allows
selecting the operation mode according to the country, where you intend to use the
radio. Please make sure that you use only the country switching which is allowed in
your country and according to your CB licence! You may risk a penalty if authority
members will find that you are operating in not allowed modes!
During first use of this radio, the radio will start in this factory preselected 40
FM / 40 AM mode:
40/40 40 channels FM / 4 Watt, 40 channels AM 4 W according to
latest European Standard EN 300 433-2, but not yet applied in all
countries. Only In Italy and Spain you still need a licence to
operate the radio, while it is already free of charges and licence
in Belgium, Bulgaria, Croatia, Cyprus, Germany, Estonia,
Finland, France , Greece, Ireland, Hungary, Latvia, Lithuania,
Luxembourg, Monaco, the Netherlands, Poland, Portugal,
Romania, Slovenia, Switzerland (starting with 2013) and
Liechtenstein. The radio comes ready for the new AM output
power of 4 Watts. Depending on the date when your country will
adopt the new European power levels, it may happen that AM is
not yet allowed to use officially in certain countries.
80/40 80 channels FM / 4 Watt, 40 channels AM / 4 W for Germany,
also for CZ (only FM) and SK (only FM 1-40 & 70-80) allowed to
use. You need no more any licence to operate the radio in this
mode, but in certain German border regions transmitting from
base stations on channels 41 to 80 in FM is not allowed (or only
with a special license).
40 FM 40 channels FM / 4 Watt (former “CEPT” settings with 40
Channels FM according to EN 300 135-2). This mode can be
used in all European countries (please see our latest issue of the
“Radio Passport”).
Please note that some countries may not allow the country switching to
German 80 channels. In October 2012, only Austria still published
restrictions to use radios with country switches within Austria.

Safety Precautions
People with pacemakers are recommended as a precaution to consult their doctor
before operating the CB radio. Not all types of pacemakers are sufficiently protected
from radiation from a nearby transmitter, so do not assume it is safe to start operation
without checking! Please remember that you are in the immediate vicinity of a
transmitting aerial, particularly when used as a mobile. If your doctor, or the
manufacturer of the pacemaker, has recommended keeping a certain safe distance
from the aerial, then please follow their instructions!
Do not transmit without connecting the aerial and never touch the aerial during
transmission!
Please also take road safety into account! CB Radio (even when only receiving,
particularly when volume is turned up) can divert your attention from the road! Road
safety is of course to be given priority! Therefore only use your AE 4200 R when the
traffic situation enables it to be used safely.

Installation of the radio
You can either operate your ALBRECHT AE 4200 ASQ in the car or at home as a
base station. For installation as a mobile station in the car, a mobile mount device is
enclosed. Mount the set in such a way that it is not exposed to direct sunlight if
possible, as this would lead to an increase in the temperature and can decrease the
(set’s) working life. The set should also not be installed near a heater. Mount the set
in such a way that it is exposed to as little vibration as possible.
The mobile fixing device should be attached to the dashboard, the tunnel slot or to
any other suitable place using the enclosed tapping screws. Do not install the set in a
place where it could cause injuries in the case of an accident (be careful to ensure
free leg movement). Take care not to damage any underlying wires during
installation!
Then insert the radio into the mobile mount device. Secure the set with the large
knurled screws (using the enclosed plastic washers) firmly at the required angle.
Also mount the microphone hanger using the enclosed screws in an easily-
accessible place.
In order to prevent interference to the vehicle electronics from transmission in the
vehicle, please make sure to take any mounting instructions from the vehicle
manufacturer for radios and antennas into account.
Please note: European directives allow the car manufacturers to decide, whether or
not private radio transceivers may be operated in cars, this is also valid for antenna
installations. Please install your mobile CB station only in accordance to car
manufacturer’s installation instructions.
Power supply
Your AE 4200 ASQ receives power from the 2 pin fixed power cable.
The red and black wires in the cable are for the power supply. The cable has a
looped-in fuse.
You can choose from two methods when connecting to the power supply (red and
black):
Example 1
The radio should be able to be switched on and off at any time using the
volume / on/off switch.
Connect up the red to the positive pole on the vehicle battery (or elsewhere
in the vehicle’s electrical system with permanent plus) or to a 12 volt power
unit.
Connect up the black wire to the negative pole on the vehicle battery or the
power unit or to a well-conductive part of the car body.

7
Example 2
The set should be automatically switched on and off with the ignition switch
of the car. The radio shall always start in last used mode on the last used
channel.
Attach the red wire to a part of the vehicle electrical system which is
interconnected to the ignition.
Connect the black wire to the negative pole on the battery or the vehicle
body.
Note for all connecting methods:
For EMC reasons, the cable used to connect to the power supply should be no longer
than 3 metres.
If you wish to operate your set at home from the mains supply then please only use
a stabilised power pack with at least 2 amps permanent current-carrying capacity.
Under no circumstances should you use a car battery charger, as these are not
stabilised and during open circuit reach such high voltage levels that your radio set
could be destroyed.
If in base station use it is important to you that the stored stations are kept even after
switching off and on again, then please do not switch the external power supply
power unit off when you switch your set off for a short time. Only use the on/off
switch on the transceiver itself.
Never repair a blown fuse with silver paper or with aluminium foil! If the fuses
keep blowing, then please give your radio set to your servicing dealer to be
repaired or hand it in to Albrecht’s service station.
The maximum allowed voltage variation for this radio is up to 15.6 volts.
Never exceed this voltage under no circumstances! The transmitting stages
for your AE 4200 ASQ are electronically stabilised, and therefore it is
impossible to increase output by means of excessive supply voltage. Such
attempts may lead to serious damage to the radio set but will never increase
output power!
Antenna connection
Connect your CB antenna to the ANT socket on the rear side of your ALBRECHT AE
4200 ASQ. Most CB antennas must be tuned to best radiation during installation to
give highest effective communication range. CB specialists do that job with a
standing wave meter to check and adjust the aerial. Tune the antenna to the best
standing wave ratio (SWR) on an intermediate channel e.g. using Channel 1 in 80/12
mode (26.965 MHz) or Channel 20 in all other modes.
On this channel you should obtain a SWR of approx. 1.5 or less. If the SWR
deteriorates on the highest (Channel 40) and lowest (Channel 41) channels up to a

8
value of 2.5, then your aerial is still acceptable. SWR above 3 is too bad for good
communication range. A bad SWR may also indicate that there is perhaps an
installation error or missing ground. Problems may be caused through missing
ground, especially in boats and motor homes with fiber glass body. For these cases,
Albrecht offers a special “ground less” antennas like GL 27.
Some antennas, like “Gamma II” (order No. 6725) are broadbanded and do
not need any retuning during installations.
Even if your AE 4200 ASQ has a particularly robust transmitter
high-level stage which can even withstand mismatching of SWR=3,
you should still never transmit without an antenna!
Operation
Before switching on
•Turn SQUELCH control left as far as possible, without turning “over the click”
Switching on and adjusting volume
The on/off switch is combined in the VOLUME control. To switch on:
•Turn VOLUME control from OFF position slightly right. LED display will be
illuminated. Then turn further until desired volume is reached.
Selecting the correct country code
Starting with 40 / 40 channel system
When you switch on your new CB radio for the first time, it will start with the latest
European channel setting with 40 channels FM and 40 channels in AM.
Note: this system is allowed in B, BG, CH, CY, CZ, D, E, EST, F, FIN, FL, GR, H,
HR, I, IRL, L, LT, LV, MC, N, NL , P, PL , RO, S, SK and SLO
40/40 This position can be used in those countries, where already all 40
international channels are allowed to be used in AM and FM. AM was
traditionally used by CB from the beginning in the early 60’s in USA, and it
is still the preferred mode of all truck drivers in the world. Please use this
mode only in countries according to the list in the Radio Passport, and
please apply for an individual licence where requested.
If necessary You can return to this system any time later by:
•Switch the radio off
•Press Down button and keep button pressed
•Switch on the radio at the same time
•Release the button

9
Switching to 80/40 channel system (Germany and CZ/SK only)
80/40 This position is only allowed to be used in Germany and CZ / SK,
because no other European countries provide the German 80 FM
channels. (Note: In Czech Republic you can use all German channels,
while in Slovak Republic use only AM (1-40) and FM on CH 1-40 & 70-
80). No individual licence is necessary, but restrictions are still in force in
certain German border regions, where transmitting on channels 41 – 80 is
not allowed or only with a special licence.
•Switch the radio off
•Press Up button and keep button pressed
•Switch on the radio at the same time
•Release the button
Switching to 40 Channels FM
Europe-wide used 40 Channels FM mode. If you are not sure what is allowed in your
country please ask local authorities before using the radio. In case of any doubt, use
this country switching as your setting:
40 FM This is former “CEPT” mode, the programming which is allowed in most
countries. Here the radio works on the international 40 Channels in FM
mode. The Mode switch AM – FM on the front side allows only receiving
in AM and FM, but only transmitting in FM mode (only a few countries like
Island, Denmark and Malta allow use of FM only.) In Austria, the radio is
not allowed to have any country switching, so authorized distributors must
disable the switch before the radio can be used in Austria.
To switch to this system
•Switch off the radio
•Press Up and Down simultaneously and keep pressed
•Switch on the radio again
•Release buttons
Please read carefully the “Radio Passport” in the last chapter of this manual
before reprogramming the unit. It is useful to take the Radio Passport with you
when travelling abroad and using 40/40 or 80/40 mode.
Note: This radio utilises a CPU system especially developed for this radio. Other
(illegal) channel systems are not stored in the CPU system and are not available at
all.
Selecting the operating channel
•with Up or Down buttons on the radio You can continuously select channels. The
present channel is displayed.
•Press the respective button longer to run up or down through the channels. The
present channel is displayed.

10
Adjusting squelch (muting)
Particularly in FM, noise can be a nuisance on a free channel. With the muting
control (SQUELCH) you can suppress this noise - but also signals which are too
weak to be received properly.
This is how to adjust the signal strength required to switch on the loudspeaker, using
the standard SQUELCH control knob:
The further the control knob is turned to the right, the stronger a signal has to be in
order to be audible through the loudspeaker.
In order to adjust the set to be the most sensitive to incoming signals, switch to a free
channel:
•Use the up / down switches to find a free channel, where no signal is
displayed.
•Then turn the SQUELCH control carefully to the right until the noise just
about disappears.
Now the loudspeaker stays off when on a free channel but it switches back on when
receiving even very weak signals.
ASQ Auto squelch mode
The radio provides in the full counter clockwise position (you
will hear a “click”) a kind of automatic squelch, which is suitable
in most receiving situations, where you want to hear all signals,
incl. distant stations, which can be received. If you should not like
to hear distant stations, you should better use the standard
squelch where you can suppress any reception below a certain
adjustable signal level.
AM / FM mode switch
In the German channel system 80/40 you can now receive on all 80 channels in FM
and AM, but You can transmit on all these channels only in FM.
In AM the only channels 1-40 are enabled for transmitting. If You should try to
transmit in AM on other channels, you will see an error (Er) message in the display.
Transmission on such channels is technically deactivated. A green control LED is on
during FM mode.
Special interest channels
There are a few channels which have been established for certain purposes:
Channel 1 Call channel in FM (Germany only)
Channel 9 Call and emergency channel, in Germany particularly this
channel is also used by all truck drivers in AM.
This means: a large number of stations are listening in. If
the worst comes to the worst (e.g. in case of accident etc.)
there is a good chance that someone will be listening.

11
To call other stations, who you know are listening in on channel 9, you can also use
this channel. Call up the desired station on channel 9. As soon as contact has been
made, agree on a free channel for your conversation and then channel 9 will be free
again for other calls.
An emergency channel can of course only work if as many stations as possible are
listening in. Therefore listen in to this channel as often as possible!
Channel 19 Trucker channel on AM in France, Spain and Italy
Channel 24/25 Data transfer (Packet Radio, Germany only)
Channel 40 Calling channel in Switzerland
Channel 40/41 CB long distance repeaters (for example in CZ in high
mountain regions)
Some recommendations have been worked out by the CB clubs for the new channels
41 to 80 in Germany. To find out which channels are suitable for special purposes,
please get in touch with the respective groups or check in CB magazines.
Transmitting and correct use of microphone
With the transmission button (Push To Talk) on the side of the microphone you can
switch between receiving and transmitting:
•Press PTT button to transmit.
Your radio is equipped with a TX control LED, this will light when You are
transmitting on an allowed channel in an allowed mode.
•Release PTT button again to switch back to receiving.
When the transmission PTT button is depressed, you can speak from a distance of
about 5-10 cm into the microphone. After pressing the PTT button, please wait about
½ second before you start speaking. Please remember- that different from GSM
phones- You share one channel common for transmit and receive, and your
transmitter and the receiver(s) on the distant side need a certain time to switch on.
The modulation amplifier of your AE 4200 ASQ is sensitive enough and enables you
in most cases to speak with even more distance, depending on how loud your voice
is. An automatic regulator ensures that your partner always hears your signal at the
same volume.
It is best to test the best distance from the microphone for yourself with the help of
another station.

12
External sockets
External loudspeaker
Depending on the surrounding noise, it can be advisable to hook up an external
loudspeaker. Usual commercial radio loudspeakers with 4-8 ohms impedance and 2-
4 W minimum output can be plugged in.
The cable can be up to 3 metres long. For car loudspeakers, make sure to use a two-
pin 3.5 mm jack plug and ensure that none of the loudspeaker connections is
attached to the vehicle chassis.
Microphone socket
Your AE 4200 ASQ has an 4 pin standard microphone socket on the front side.
The wiring corresponds to international standards used by many manufacturers since
many years.
Apart from the hand microphone included in the package, you can also hook up other
microphones, with or without preamplifier, or with or without data transmitting
devices. According to the latest regulations you are also allowed to plug in modems
or so-called TNC`s for data transfer (Packet Radio). However, other type of
microphones must be specially soldered to the 4 pin connector.
Please note that data transfer is only permitted on certain channels and only for non-
commercial use and not in all countries.
Service and Warranty information
Troubleshooting
Check at first the power supply and the fuse. A problem may be caused through
power supply, when no LED light appears after switching on. If the unit works in a
strange way, disconnect the power supply cable (or take out the fuse from the
holder), while the radio remains switched on, wait some time (minimum 10 seconds),
and then reconnect power cord again.
Check the microphone and antenna connector. We think you cannot do more in case
of a problem. Please ask your dealer or consult our service hints in the Internet. If
you should return the radio to your dealer for repair, do not forget to describe the
problem as exactly as possible.
