(3) Major Features
l Large LCD
A large rear illuminated liquid crystal display (LCD)
provides display of receive frequency, mode, etc plus alpha
numeric text along with each search bank and memory
channel.
l Massive memory
A large EEPROM memory store holds a total of 1000
memory channels (100 ch x 10 banks), and 20 search
banks. Each search bank has a total of 100 PASS
frequencies plus a further 100 for VFO operation. This
type of memory store does not require external power or
internal battery power to retain the memory contents. The
real time clock is backed by an additional super capacitor
which will maintain the correct time for approximately 50
hours even with no external power connected to the
receiver.
l Wide frequency coverage, all mode, automode
The AR5000 has a very wide frequency coverage of
10kHz to 2600MHz (acceptable input from 5 kHz) in FM,
AM, USB, LSB & CW. The all new receive circuitry
provides high sensitivity and superior strong signal handling
thanks to the clever RF design which is optimised to each
receiving band with electronic tuning (pre-selector) circuits
up to 1GHz.
Comprehensive bandplan information specific to the target
market area has been programmed into the AR5000
receiver. This inclusion will greatly simplify both frequency
entry and search programming.
The receiver will
automatically
select the appropriate mode
and channel step. Of course, should you wish then both
the mode and channel step may be manually changed as
desired.

(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 via the power jack and
earphone sockets.
Avoid static discharge from discones or long wire aerials,
earth 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 power switch On/Off sequence. If switched
off, leave at least two seconds before switching on again.
Ensure the a.c. mains plug connections are tight and other
d.c. connections (such as cigar lighter plugs) are secure.
Avoid strong RF fields from nearby transmitters. If in doubt,
disconnect the AR5000 from the aerial and switch the set
off.
