AOR AR7000 User Manual

1 Introduction
Thank you for purchasing the AR7000 wide band all mode receiver. The AR7000 is
designed using DSP (Digital Signal Processing) technology to ensure the highest
levels of performance and reliability. To get the best possible results from your
AR7000 we recommended that you read this manual and familiarise yourself with the
receiver. Although carefully designed, this receiver (like all receivers) suffers from a
degree of internal noises known as spurii which are a product of the receiver’s
circuitry and do not represent a fault. Apparent faults may be due to accidental mis-
operation of the receiver, if you think there is a problem, carefully read all of the
manual before deciding to return the receiver for repair.
Every effort has been made to make this manual correct and up to date. Due to
continuous development of the receiver and by error or omission anomalies may be
found and this is acknowledged.

2 Standard supplied accessories
1 x Power supply (a.c. to d.c., input voltage dependant on market)
1 x Infrared remote controller
1 x Operating manual (this booklet)
3 For your safety
There are no internal operator adjustments. In the unlikely event of servicing being
required, please contact your dealer for technical assistance.
The AR7000 is designed for operation from its supplied a.c.-to-d.c. adapter.
Operation is possible from a d.c. supply of 12 to 14V, which should be able to supply
up to 2.0A. Never connect the AR7000 directly to the a.c. supply.
Do not use or leave the receiver in direct sunlight (especially the LCD). It is best to
avoid locations where excessive heat, humidity, dust and vibration are expected.
Always treat the receiver with care. Take care to avoid spillage or leakage of liquids
into the receiver and a.c. power supply. Special care should be taken to avoid liquid
entering around the controls, through the speaker grille or via the connection jacks.
If fitting a separate external earth rod, consider the implications carefully if your
buildings’ a.c. supply uses a Protective Multiple Earth (PME) system. If in doubt
consult an expert electrician. Never earth to a gas pipe!
The AR7000 has a single BNC aerial socket for all frequencies. This socket is
intended for connection of a 50 OHM (unbalanced) coaxial fed aerial such as a
discone, dipole, unipole, yagi etc. When sighting the aerial, avoid power cables. A
telescopic whip may be connected to this socket for local monitoring.
