Section 1-2, 1-3, 1-4, 1-5

1-2 Taking care of the unit

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 SDU5500 in direct sunlight (especially the LCD). It is best to avoid locations
where excessive heat, humidity, dust and vibration are expected. Always keep the SDU5500 free from
dust and moisture. LCD contrast & selection of negative / positive display may be adjusted via menus,
adjust appropriately to your operating environment.
Note: Never push or knock the LCD screen - which is very fragile and shock sensitive.
Daily care
Use a soft, dry cloth to gently wipe the SDU5500 clean, never use abrasive cleaners or organic solvents
which may damage certain parts. Treat the unit with care, avoid spillage or leakage of liquids into the
cabinet and power supply. Special care should be taken to avoid liquid entering around the keys, spin
wheel dial or via the connection sockets.

1-3 Power requirements

Depending upon the world market area, the SDU5500 may be provided with either a suitable a.c./d.c.
power unit or just the d.c. lead with correct d.c. plug type fitted. The SDU5500 is designed for operation
from a nominal 12V d.c. regulated power supply (12 to 14V is acceptable), which should be capable of
supplying a minimum of 1A continuous, ideally a 2A unit should be employed.
Note: Never connect the SDU5500 directly to an a.c. supply.
The d.c. input socket uses a mini power connector subject to EIAJ RC-5320A
and is wired centre positive (+), the cable is marked with a stripe identifying the
positive connection, the chassis of the unit is at negative ground. To minimise
the potential for power cable interference, it is suggested that a ferrite clamp be
fitted to the connecting cable.
SAFETY NOTICE - Always disconnect the power supply from the a.c. socket when not in use.

1-4 Operating anomalies

Should the SDU5500 appear to behave strangely, normal operation may easily be regained by resetting
the microprocessor. Simply power down the SDU5500 and disconnect the power supply... leave for 30
seconds then re-connect and power-up again.

1-5 Accessories supplied

The following items are provided in the carton box:
1 x Control lead for the AR5000 (9-pin to 9-pin D-type male)
1 x BNC patch lead for IF connection
1 x Operating manual
1 x a.c. power supply or d.c. cable
(in this case the white stripe is positive) - depending upon world market area.
Note: If used with the AR3000A, a small modification is required to the receiver in order to provide
the required 10.7 MHz IF output. If using the ICOM IC-R7100 or IC-R9000, the optional ICOM CT17
(RS232/CIV) interface is required.
