Taking Care Of Your Receiver - AOR AR-DV1 Operating Manual

1-2 TAKING CARE OF YOUR RECEIVER

There are no internal operator adjustments needed. In the unlikely event service is required; please
contact us for technical assistance.
Do not use or leave the receiver in direct sunlight. It is best to avoid locations where excessive heat,
humidity, dust, and vibrations are present. Always keep the AR-DV1 free from dust and moisture. Use a
soft, dry cloth to gently wipe the external surfaces clean; never use abrasive cleaners or organic solvents
which may damage certain parts.
Treat the AR-DV1 with care; avoid spilling liquids into the receiver and the associated power supply.
Special care should be taken to avoid liquids from entering the area around the controls and through the
speaker grill or via the connection jacks.
The AR-DV1 is designed to operate from a good quality regulated DC power supply of 10.8 to
16.0 V, which should be capable of supplying 1 A. Never connect the AR-DV1 directly to an AC power
outlet.
The polarity of the DC input jack is clearly marked (center positive); the chassis of the receiver is at
negative ground.
SAFETY NOTICE – Always disconnect the power supply from the AC outlet when the
receiver is not in use for a long period of time. If used mobile, note that the AR-DV1 has
NOT been manufactured or tested to meet any specific mobile safety requirements. The
AR-DV1 has no user adjustable internal parts.
When using the AR-DV1 as a base station, the best short wave reception is usually achieved through the
use of a separate external earth (or ground) rod. However, consider the implications carefully if your AC
building supply uses a Protective Multiple Earth (PME) system. If in doubt, consult a qualified electrician.
Never earth (ground) to a gas pipe! The antenna connector of the AR-DV1 is intended for connection to a
50 Ohm (unbalanced) coaxial fed antenna such as a discone, dipole, Yagi, etc.
Avoid power cables when installing an antenna.
Operating anomalies
Should the AR-DV1 appear to behave strangely, normal operations may be easily achieved by performing
the following steps:
Symptom: No control of the receiver or the display appears to be frozen
Action: Turn off the power switch on the front panel. Leave it off for approximately 10 seconds.
Turn the power switch back on again. Normal operation should be restored.
Should the receiver still behave strangely, try a RESET as explained in chapter 11-5.
