Introduction; Taking Care Of The Unit; Power Requirements - AOR SDU5600 Instruction Manual

1-1 Introduction

Thank you for purchasing the SDU5600 Spectrum Display Unit. For many years, AOR has been
marketing the world's first color spectrum display unit, SDU5000 for professionals and the high-
end of hobby listeners. The SDU5500 was a worthy successor to the SDU5000, suing a large
high resolution LCD. The SDU5600 is the "next generation" in spectrum display units. Using a
five-inch TFT color display, DSP (Digital Signal Processing) and FFT (Fast Fourier Transform),
faster sampling rates and color imaging, the SDU5600 opens the door to new possibilities and
applications. To get the best possible results, we recommend that you read this manual to fully
familiarize yourself with the SDU5600.
Every effort has been made to make this manual correct and up to date. Due to continuous
development of the product and by error or omission, anomalies may be found and this is
acknowledged.

1-2 Maintaining 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 SDU5600 in direct sunlight (especially the LCD). It is best to avoid
locations where excessive heat, humidity, dust and vibration are expected. Always keep the
SDU5600 free from dust and moisture. LCD contrast and brightness may be adjusted via menus,
adjust appropriately to your operating environment.
[Note: Never push or knock the LCD screen – it is very fragile and sensitive to shock.]
Daily care
Use a soft, dry cloth to gently wipe the SDU5600 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, rotary dial encoder or via the connectors.

1-3 Power requirements

The SDU5600 comes with a 120 V AC adapter. The SDU5600 is designed for operation from a
nominal 12 V DC regulated power supply (12 to 14 V is acceptable), which should be capable of
supplying a minimum of 1 amp continuous, ideally a 2 amp power supply unit should be used.
[Note: Never connect the SDU5600 directly to an AC outlet.]
The DC power jack uses a mini power connector conforming to EIAJ RC-5320A and is wired
center positive (+), the chassis of the unit is at negative ground. To minimize the potential for
power cable interference, it is suggested that a ferrite clamp be fitted to the power cable.
[Safety Notice: Always disconnect the power supply from the AC outlet when not in use.]
