1-1 Introduction

Thank you for purchasing the AR8600 transportable wide band all mode receiver. The AR8600 is

designed using the very latest technology to ensure the highest levels of performance and reliability.

To get the best possible results from your AR8600 we recommend 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. They are a product of the receiver’s circuitry

and do not represent a fault. Apparent faults may be due to accidental misoperation of the receiver, if

you think there is a problem, carefully read all of the manual before deciding to contact your equipment

supplier for advice.

It is acknowledged that sections of this manual are repetitive, this is to enable the manual to be used as

a reference book (you don’t have to read it all from cover to cover in one go). Due to the international

nature of the product, some graphics contain Japanese characters.

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.

1-2 Take care of your radio

There are no internal operator adjustments. In the unlikely event of servicing being required, please

contact your dealer for technical assistance.

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 keep the AR8600 free from

dust and moisture. Use a soft, dry cloth to gently wipe the set clean, never use abrasive cleaners or

organic solvents which may damage certain parts. Treat the AR8600 with care, avoid spillage or

leakage of liquids into the receiver and associated power supply. Special care should be taken to

avoid liquid entering around the controls, through the speaker grille or via the connection jacks.

The AR8600 is designed for operation from a good quality regulated d.c. supply of 12 to 14V, which

should be capable of supplying 1Ampre. Never connect the AR8600 directly to the a.c. supply.

The AR8600 also has the provision of the optional BP8600 NiCad battery pack, see section 1-6-1.

The d.c. input socket uses a 2.1mm power connector. This connector is configured CENTRE

POSITIVE, the chassis of the receiver is at negative ground. Where provided (depending upon world

market location), the power supply is pre-wired and provides a nominal 12V d.c. output with suitable

connectors being fitted as standard for the a.c. power input and connection to the AR8600.

SAFETY NOTICE - Always disconnect the power supply from the a.c. socket when not in use.

If used mobile, it should be noted that the AR8600 has not been manufactured

or tested to meet any specific mobile safely requirements. The AR8600 has no internally

user adjustable parts, refer any technical work such as the fitting of the optional

BP8600 internal NiCad battery pack to an authorised service engineer.

If using the AR8600 in a base station situation, the best short wave reception is usually achieved by the

fitting of a separate external earth rod, however consider the implications carefully if your a.c. building

supply uses a Protective Multiple Earth (PME) system. If in doubt consult an expert electrician. Never

earth to a gas pipe!

The AR8600 has a single BNC aerial socket for all frequencies. This is intended for connection to its

supplied whip aerial or preferably a 50 OHM (unbalanced) coaxial fed aerial such as a discone, dipole,

unipole, yagi etc. When sighting the aerial, avoid power cables. Ensure that you do not confuse the

aerial and i.f. output sockets as they both employ BNC sockets.
