the internal speaker, the amplifier provides more than 2
WATTS of audio - there are even treble and bass controls.
A stereo 3.5mm front panel socket provides headphone
output from a separate internal stereo amplifier and may
drive mono or stereo 'phones. The auxiliary outputs (left
and right) have separately adjustable levels and may be
used to drive an external recorder or data decoders.
Dot matrix LCD
A 48 character, rear illuminated dot matrix LCD with rear
panel adjustable contrast provides a huge amount of
information, a wide range accurate signal meter and text
based menus.
Assignable controls
Assignable controls enable you to place the functions YOU
want at your fingertips - they retain the last used operation
when the menus are removed, and include a press button
and a spin-wheel

Infrared remote controller

A full featured 32 button infrared remote control is provided
as standard and provides access to all commonly used
facilities, including: tuning, volume, tone, memory
functions, pass band shift and filter selection, as well as
providing a numeric keypad for direct frequency entry.
TWO infrared sensors are employed, one on the front
panel and one on the rear, so that the controller may be
used from almost any position around the receiver.
Stylish strong cabinet
The AR7030 features a custom CNC machined solid
aluminium front panel with extruded aluminium shaped
sides, metal top, bottom and rear panels. The front panel
finish is brushed and anodised with the sides and other
surfaces toned in a matching textured paint. Smooth
curved lines, detailed panel breaks, top mounted domed
speaker grille and ergonomically placed controls spell out
the attention to detail of this robust, solid cabinet.

4 Precautions

4-1 Location

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.
Avoid static discharge from aerial systems especially when
using long wires - earth them to a central heating radiator
or similar earthing point in order to discharge the wire
before connection to the receiver. Always disconnect and
earth any external aerial system if an electrical storm is
expected.

.
Avoid a rapid disconnection then reconnection of the power
supply. If disconnected, leave at least two seconds before
reconnecting again. Ensure that all power connections are
secure.
Avoid strong RF fields from nearby transmitters. If in doubt,
disconnect the AR7030 from the aerial and switch the set
off.

4-2 Looking after your receiver

Always keep the receiver free from dust and water. Use a
soft, dry cloth to gently wipe the set clean. Never use
abrasive cleaners or organic solvents which may damage
certain parts.

4-3 Power requirements

The AR7030 is designed for operation from its supplied
mains adapter. Operation is possible from a d.c. supply
of 12 to 15V, which should be able to supply up to 800mA,
but for full performance always power the receiver from
15V d.c rather than from 12V. (The receiver's frequency
coverage is not guaranteed above 30 MHz when operating
from a 12V supply).
EMC NOTICE - This receiver may not fully comply
with the E.C. EMC directive if operated from an
external power source other than the supplied AC
adapter.
The d.c. input socket uses a 2.1mm coaxial power
connector, and a 14mm long plug is recommended. This
connector is configured CENTRE POSITIVE, the chassis
of the receiver is at negative ground. The low noise power
supply provided is pre-wired and provides a regulated 15V
d.c. output with suitable connectors being fitted as standard
for the a.c. mains input and connection to the AR7030.
The AR7030 has a rear panel socket for connection of an
RF earth, allowing a separate earth to be taken to a water
pipe, central heating system radiator or external earth rod.
If fitting a separate external earth rod, consider the
implications carefully if your mains supply uses a Protective
Multiple Earth (PME) system. If in doubt consult an expert
electrician. Never earth to a gas pipe!
SAFETY NOTICE - Always disconnect the power
supply from the a.c mains when not in use.

4-4 Aerial (antenna) connection

The AR7030 has two aerial inputs, selected by a rear panel
switch, allowing three basic types of connection (the actual
choice of suitable aerial is almost limitless).
1. 50 OHM (unbalanced) SO239 socket for connection
of dipoles, long wires with matching devices, active aerials,
verticals, yagis etc.
2. WHIP may be selected to activate an impedance
matching amplifier when a telescopic aerial or very short
wire is fitted to the 50 OHM SO239 socket.
3. WIRE aerial input is used for connection of long wire
or similar relatively high impedance aerial systems.
