better FM modulation. But especially the truckers loved the CB traditions und are still using the
amplitude modulation, while the less interfering truck diesel motors even create some advantages
compared to the FM modulation: the sound was not as aggressive and a lower noise on unused
channels.
Meanwhile the administrations reconsidered AM again as acceptable and more and more
European countries allowed AM again, meanwhile mostly without registrations and license fees.
With the function key A/F you can choose between AM and FM. (The modulation type will be
shown in the display.) FM devices for Austria do not have any function on this key.
In AM you can only transmit with your radio, if you have programmed the 80/40 or 40/40 mode and
if you chose a channel on which AM is allowed from the transmitting side.
As soon as you try to switch to a channel between 41 and 80 in AM, the radio automatically
switches to the 40 channel AM mode with the channels 1 to 40 (and reverse in the German setting)
Both modulation types have their own channel setting, so after a swap you always come back to
your last used AM respectively FM channel.

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 AE6690 has a 6 pin microphone standard socket on the front side. To enable the additional
channel selecting function UP and Down from the microphone, the socket has a special wiring at
Pin No. 4 only valid for this and similar Albrecht transceivers.
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 6 pin
connector and do not allow additional switches. Such other microphones must not use PIN 4 of the
plug.
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 the LCD is not on after switching the radio 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.
