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.
Please never return any radio to our service partner without consulting the technical
Hotline via phone or e-mail.
Many small problems can be cleared already via phone or mail, and in case that a
service repair should really be necessary, the Hotline will be able to tell you the
nearest and most fast service partner for your radio!
