Important Note Your Albrecht AE 5090 corresponds to the latest European CB standards. As a unique feature, it has a country switch which allows selecting the operation mode according to the country, where You intend to use the radio. Please make sure that You put the country switch on the front side of the radio into the correct position before installing and connecting the power supply! 40 FM 40 channels FM / 4 Watt (former “CEPT” settings with 40 Channels FM according to EN 300 135-2).
• Socket for external loudspeaker • Rugged , noise-reduced dynamic “Trucker” microphone • Conventional Squelch + additional ASC noise reduction system Please read this operating manual through carefully. This will enable you to make use of all the functions your new CB Radio has to offer as soon as possible.

Country switch setting before installation Before You switch on Your new CB radio, You should preset the country switch on the front panel of the radio according to the local authority requirements. If You are not sure and if You should not have any individual CB licence issued by the telecommunications authority of the country where You live, You should use the factory default setting of the switch: This is the left position on the picture, 40 FM.
Installation of the radio You can either operate your ALBRECHT AE 5090 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.
An non volatile flash memory keeps the channel and country information stored even if the radio is not connected to power. 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 stabilized power pack with at least 2 amps permanent current-carrying capacity.
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 connecting cable with matching box as “artificial ground” (AKM 27) Some antennas, like “Gamma II” are broadbanded and do not need any retuning during installations.
Please note: Squelch and ASC settings may require re-adjusting in low sensitivity position. Adjusting SQUELCH (muting) and ASC Particularly in FM, noise can be a nuisance on a free channel. To suppress as much noise as possible, Your radio is equipped not only with an ordinary muting control (SQUELCH) like all CB radios have, but has also a preinstalled ASC circuit (patented by GPE). Both circuits can be preset and adjusted independent of each other.
engine or wiper as a signal and will open, because the squelch cannot distinguish between a wanted signal and an unwanted interference. If You would have preset the ASC at switched-off engine before, the interference coming from the wiper motor would be detected and the ASC circuit would shift the threshold point so long automatically, until the interference will disappear. The radio will remain muted, but stay on the highest sensitivity level during the whole procedure studied in this example.
MEMO Modus Using the 5 direct channel buttons You can switch at any time from the present channel (normal channel modus) to the 5 programmable stored stations (MEMO modus) and switch back again. Recall direct channels • Press one of the 5 direct channel buttons briefly. The unit will switch to the pre programmed channel. The channel number and the button number will displayed.
Switching back to normal channel selection • Simply turn the rotary knob or press up or down on microphone. • The display of direct button numbers disappears and the channel selection works again via microphone or rotary knob. Channel scan Your AE 5090 has an automatic channel scan, which can be used for all channels. First choose the mode of operation (normal channel modus or MEMO modus). Adjust the muting control to the point at which the receiver should open (see also ‘Adjusting squelch’).
Direct channel 9 access Just press the button and the channel will be changed to the international calling- and emergency channel 9. Channel display will be blinking. To go back to the original channel, just press knob once more. 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. The display shows TX . • Release PTT button again to switch back to receiving.
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 24 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.
Service and Warranty informations Troubleshooting Check at first the power supply and the fuse. A problem max be caused through power supply, when no light appears after switching on. If the unit works in a strange way, disconnect the power supply cable, while the radio remains switched on, wait some time (minimum 10 seconds), and then reconnect power again. Check the microphone and antenna connector. We think You cannot do more in case of a problem.
Legal Information The radio may be used in European Countries only according to following information, which we publish as “Radio Passport”. Because the number of countries allowing the new AM standard is changing, the latest version of this radio passport is published on our Internet Web server and may be downloaded any time.
