Albrecht AE4090 CB Radio Operating Manual

							 
 11
  When you switch on the set the first time it operates on FM. 
  
Special interest channels 
There are a few channels which have established themselves 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.  
 
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 16  Water sport channel 
Channel 19  Trucker channel on AM in France, Spain and Italy 
Channel 24/25 Data transfer (Packet Radio, Germany only) 
 
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.  
 
 
Direct channel access key CH9/19 
Your transceiver has an extra button on the microphone which provides direct 
access to the most important channels 9 and 19 described in previous chapter. 
You can toggle with the button between “normal” channel selected previously, CH 9, 
CH 19 and back again. Just press the button consequently. 
 
 
Scan mode 
Your AE 4090 has an automatic channel scan, which can be used to observe all 
channels consequently. 
First choose the mode (AM or FM). Adjust the muting control to the point at which the 
receiver should open (see also ‘Adjusting squelch’). 
 
Start channel scan 
· Briefly press the button SCAN. 
· Scan starts almost immediately by scanning all the channels upwards 
· Scanning is stopped at each signal worth receiving and you can listen in to the 
conversation.  
If you leave the set alone it will re-start a) after the communication on the channels 
has stopped or b) after about 5 seconds observation time, if the communication 
should last longer.

  Stop channel scan 
· You can stop the scan at any time by pressing the SCAN button a second time. 
· Pressing the transmission button will also automatically stop the scan modus. 
 
 
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. 
If Your radio is equipped with a TX control LED, this will light when You 
are transmitting on an allowed channel in an allowed mode. (Note: Some 
versions of this radio do not have a TX- LED) 
 
· 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 4090 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.  
 
 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 are  
attached to the vehicle chassis. 
 
Microphone socket 
Your AE 4090 has an 8 pin microphone socket on the front side. To enable the 
additional functions, like UP/Down, Scan and direct channel control 9/19 from the 
microphone, the socket has a special wiring only valid for this transceiver model.  
 
Apart from the hand microphone included in the package, you can also hook up 
other microphones, with or without preamplifier, or with or without selective calling 
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 8 pin connector and do not allow 
CH9/19, UP down or Scan switching.

  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 informations 
 
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.

Your dealer for repair, do not forget to describe the problem as exactly as possible.

This declaration is issued under our sole responsibility. Basing on not harmonised frequency applications, the CB radio may be 
used only in listed countries according to selected channel programming. An individual licence for operating this radio in AM + 
FM  (80/12 in D,  40/40 in B, CH, D, E, F, I, P) is requested.  In Finland and Netherlands 40/40 operation is free of licence. If 
the radio is programmed to 40 FM only, it may be used without license and free of charge in nearly all EU Countries + Island, 
Switzerland, Norway, Hungary  (except Austria, Italy, where individual licence is requested).  Residents of Belgium, Spain, 
Switzerland and Great Britain (UK) need a CB licence in their home country, while travellers from other European countries 
may use 40 CH FM  during travelling in these countries free of licence and charges.  
 
Diese Erklärung wird unter unserer alleinigen Verantwortung abgegeben. Dieses Funkgerät darf wegen der nicht 
harmonisierten Frequenzanwendungen in AM + FM nur mit gültiger Einzelgenehmigung bzw -Zuteilung in den Ländern 
B, CH, E, F, I, P  (40 / 40 Kanäle) und D (80/12 oder 40/40 Kanäle) in Betrieb genommen werden.  In den Niederlanden und 
Finnland ist der Betrieb auf 40/40 Kanälen anmelde- und gebührenfrei. In Deutschland ist mit der Programmierung 80/12 
Sendebetrieb  auf den Kanälen 41 - 80 in bestimmten Regionen entlang der Grenzen der Bundesrepublik Deutschland nicht 
oder nur mit Sondergenehmigung gestattet. Mit Programmierung 40/40 darf dieses Gerät auch in Deutschland betrieben 
werden, jedoch darf  in AM (bis auf weiteres) nur auf den Kanälen 4-15 gesendet werden. Mit der Programmierung 40 FM 
kann das Gerät in fast allen EU Staaten (ausser Italien und Österreich, dort ist eine individuelle Bewilligung des örtlichen 
Fernmeldebüros notwendig) anmelde- und gebührenfrei benutzt werden. Bewohner von Belgien, Grossbritannien, Spanien und 
der Schweiz benötigen in Ihrem Heimatland eine Genehmigung (CB Licence). Die vorübergehende Benutzung von 40 Kanälen 
FM durch Reisende aus anderen europäischen Ländern ist in diesen Ländern jedoch anmelde- und gebührenfrei erlaubt.
