AR3030 operating manual
peripherals such as tape recorders, weather facsimile printers, aerials and the
power supply. Switch the receiver off and leave for one minute. Reconnect the
power supply and test again.
Should the receiver still refuse to operate correctly, turn the set up-side-down
and locate a small hole in the bottom cabinet close to the main rotary tuning
control. This hole provides access to the microprocessor reset switch.
With the AR3030 connected to it's power supply and switched On,
momentarily press this switch and release using preferably a non conductive
thin probe such as a cocktail stick or cotton bud. This action will reset the
microprocessor.
Should the receiver fail to power up, check the power supply and mains fuse.
The AR3030 does contain an internal DC power fuse but should it blow we
suggest you contact your dealer for advise and service... there must be a
reason for the fuse to blow!
If the above does not help, please contact your dealer for assistance.
We acknowledge that many listeners like to have service information
available if purely for interest. For this reason a service manual should be
available through dealers as an option.
(10) Aerials (Antennas) and earth systems
The subject of aerial choice and earth can be quite complex. There are many
advantages and disadvantages to consider before connecting an external aerial
to your receiver.
Theory and practice
One interesting phenomena is that aerial theory and practice can be
surprisingly different. Keeping common sense in mind it is one of the
few remaining areas for listeners to easily experiment and often achieve
fantastic results.
Mounting location
It is important to mount any aerial as high as possible and in clear space
although this is more important at VHF frequencies than for shortwave. If
possible the aerial should have a clear path to the horizon. Results are usually
disappointing when an installation is in a loft space.
Telescopic whip aerials
Whip aerials may be connected to the 50 OHM BNC aerial input of the AR3030
and the whip aerial switch position selected. The selection of "WHIP" adds a
small preamplification to the receiver's input stages and matches the very high
impedance of the whip to the receiver's circuitry.
