Important Note:
Only the green colored country codes (page 1) are legal codes to be used for standard CB radio
purpose by any CB users in the European Union & R&TTE Countries. In some countries licensing
procedures with 1 x or regular costs may apply
The blue colored amateur radio codes may be used by persons, who have a valid amateur radio license
issued by a European member state authority.
The red colored codes are not for use in European countries. In some countries it may be allowed that
radio amateurs can own radios where all country codes can be activated, but even if that is the case,
radio amateurs are only allowed to use the dedicated amateur radio frequencies. In that case, the radio
is not allowed to be used for any other purpose than for amateur radio.

Modifications for Amateur Radio use
General: The radio is shipped as CB radio with factory pre-
programmed limitation to the green marked CB radio standards.
In Europe and USA. CB radio users can select between the modes
Code d, Code EU, Code E, Code PL, Code U, and Code US.
Radio amateurs with a valid radio amateur license can expand the
radio to Code 1 to Code 4 modes. Code 1 covers the amateur band
28.000 to 29.699 MHz, Code 2 the 12 m band and Code 3 is a
summary of all technically possible Frequencies in a CB like radio
channel mode with 450 channels, which is in use in some Eastern
European countries for CB radio. Code 4 is the same, but with –5 kHz
offset according to the Poland CB frequency system.
Amateurs are allowed to use Code 1 and Code 2 (Code 2 only in
countries where the 12 m band is allowed). In Germany, amateurs with
license may operate radios which are totally open in their frequency
range (that means incl. Code 3 and 4, but the use is restricted to the
allocated amateur Radio frequency bands and the use as amateur
radio.
That means that any other use (for example as CB radio or commercial
radio for business purposes) is forbidden for amateurs.
After any of the codes has been selected, it is possible to restrict the
radio to exactly this one code by soldering a jumper (solder bridge)
between position 4 and 5. In that case the radio can work only in one
code as long as the jumper is soldered.
Codes and its Corresponding Mode Channel Setting
Code 1: 10 m Ham Band (AM/FM/SSB 4W)
Code 2: 12m Ham Band (AM/FM/SSB 4W)
Code 3: 450ch. (AM/FM/SSB 4W)
Code 4: 450ch. (AM/FM/SSB 4W “0” Raster 0 Raster)
Code d: CB Germany (80 FM4W; 40 AM 1W and SSB 4W).
Code EU: CB Europe 40AM 1W, 40 FM/SSB 4W
Code E: CB Spain & Europe(future) 40CH AM/FM/SSB 4W
Code PL: CB Poland 40ch. AM/FM/SSB 4W “0” Raster
Code U: ` CB UK; U1 from 1to 40 UK; U2 from 1to 40 INT
Code US: USA 40 CH with (AM/SSB 4W) (no FM)
*Frequency display is not necessary for UK mode
Channel Conversion option of Code: d, EU, E, PL, U and US
only
1. Turn Off the unit (Volume switch off)
2. Press ML/MS button & hold
3. Turn ON the unit
4. Release ML/MS button
5. The display will show the code: d, EU, E, PL, U and US.
And then press the “UP/DOWN” buttons to select the desired
code.
6. Turn OFF the unit to set the selected code
7. Turn ON the unit to operate on the selected code
C. Channel conversion from code: 1 to Code: US
1. Turn OFF the unit
2. Open the PTT button by removing the rubber cover.
3. Below the PTT switch you find five soldering contact terminals
provided for conversion. Terminal 1,2,3,4 and 5.
1 2 3
4 5
4. Connect the terminals 1 and 2 together by a tool (e.g. tweezers)
5. Switch the radio ON
6. Select the desired code number (with UP/DWN)
7. Switch the radio off
8. Release the temporary connection
7. Use the radio
Restrict radio to only 1 selected code:
Select the code, solder a jumper between 4 and 5
Now the radio works only with the previously selected country code
and cannot change the code as long as the jumper remains soldered.

Modifikationen für Amateurfunkbetrieb
Allgemeines: Das Gerät wird ab Werk als CB Funkgerät programmiert
vertrieben. Es kann auf die in Europa und USA üblichen CB Standards
umgeschaltet werden. Dazu wählt man (siehe Anleitung) zwischen
Code d, Code EU, Code E, Code PL, Code U, and Code US.
Funkamateure mit gültiger Amateurfunkgenehmigung (“Lizenz”)
dürfen den Programmierumfang dieses Geräts auf den
Amateurfunk erweitern, z.B. im 10 m Band Bereich 28.000 MHz bis
29.699 MHz bei Code 1. Code 2 umfasst das 12 m Band and Code 3
ist eine Zusammenstellung aller möglichen Frequenzen in einer an den
CB Funk angelehnten Bandsammlung in Kanalform (450 Kanäle), die
in einigen Ländern Osteuropas als CB Funk genutzt werden. Code 4
ist das gleiche, jedoch mit – 5kHz Versatz wie beim CB Funk in Polen.
Funkamateure dürfen Code 1 und Code 2 benutzen (Code 2 nur in den
Ländern, wo das 12 m Band als Amateurfunkband freigegeben ist). In
Deutschland dürfen Funkamateure auch mit Geräten arbeiten, bei
denen alle Frequenzen freigeschaltet sind (z.B. incl. Code 3 and 4),
aber der Sendebetrieb ist nur auf den zugewiesenen Amateurfunk-
Frequenzen und auch nur zu Amateurfunkzwecken gestattet. Andere
Verwendungszwecke (z.B. als CB Gerät oder für kommerzielle Zwecke
sind nicht gestattet.
Nachdem einer der Codes ausgewählt wurde, ist es auch möglich, das
Gerät genau auf diesen einen Code zu beschränken. Dazu gibt es eine
lötbare Brücke zwischen den Positionen 4 und 5. Solange dort eine
Brücke gelötet ist, arbeitet das Gerät nur im zuletzt eingestellten Code.
Codes and zugehörige Multi Standard Einstellungen
Code 1: 10 m Amateurband (AM/FM/SSB 4W)
Code 2: 12 m Amateurband (AM/FM/SSB 4W)
Code 3: 450 Kanäle (AM/FM/SSB 4W)
Code 4: 450 Kanäle (AM/FM/SSB 4W “0” Raster)
Code d: CB Deutschland (80 FM4W; 40 AM 1W, SSB 4W).
Code EU: CB Europa 40 Kanäle AM 1W, 40 FM/SSB 4W
Code E: CB Spanien +zukünftige EU Norm 40 Kanäle
AM/FM/SSB 4W

5. Im Display erscheint einer der Codes: d, EU, E, PL, U oder US.
Mit “UP/DOWN” den gewünschten Code auswählen.
6. Gerät ausschalten
7. Gerät wieder einschalten und benutzen.
C. Umstellprozedur für Erweiterung auf alle Codes (Code 1
bis US)
1. Gerät ausschalten
2. Gummi der PTT Tastenabdeckung am unteren Ende abhebeln.
3. Unter der PTT Taste finden Sie 5 lötbare Kontaktflächen mit den
Nummern 1,2,3 und 4 und 5.
1 2 3
4 5
4. Kontakte 1 und 2 mit Pinzette oder Zange überbrücken und
überbrückt halten
5. Gerät einschalten
6. Gewünschten Code aussuchen (mit UP/DWN)
7. Gerät ausschalten
8. Kurzschluss wieder entfernen
7. Gerät einschalten und benutzen, Gummi wieder anbringen
Gerät auf genau 1 Code beschränken:

aus. Löten Sie eine Brücke zwischen den Positionen 4 und 5 ein.
Jetzt arbeitet das Gerät nur noch mit dem vorher eingestellten Code,
solange die Lötbrücke zwischen 4 und 5 bestehen bleibt.
