AD824—Owner’s Manual
Cautions
• Allow enough free space around the unit for normal ventilation. This should be: 10 cm
at the sides, 15 cm behind, and 30 cm above. These distances should also be adopted
when rack-mounting the AD824. For normal ventilation during use, remove the rear
of the rack or open a ventilation hole. If the airflow is not adequate, the AD824 will heat
up inside and may cause a fire.
• Use the AD824 in an environment with a temperature of between 10˚C and 35˚C (50˚F
and 95˚F).
• Turn off all equipment before connecting it to the AD824, and use only the cables spec-
ified in the relevant owner’s manuals.
• If you plan not to use the AD824 for a long period of time, remove the power cord from
the AC outlet. Leaving the AD824 connected is a potential fire hazard.
• Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean the
AD824. Use only a soft, dry cloth.
• If the AD824 is stored in a cold place (e.g., overnight in a car), and then moved to a
warmer environment, or the temperature rises sharply, condensation may form inside
the AD824, which may affect performance. In such cases, the AD824 should be allowed
to acclimatize for about one hour before use.
• When the wordclock source is changed on the wordclock master device (e.g., this
AD824, a DME32 or 02R), noise may occur from the outputs of the wordclock slave
devices, especially a AD824 with an MY8-AT I/O card installed, so turn down your
power amps beforehand, otherwise any connected speakers may be damaged.
• If the error code “E1” or “E3” appears on the GAIN display when the AD824 is turned
on, see your dealer about changing the internal backup battery. Although the AD824
will work even when the battery voltage is low, it may not remember the current settings
next time it’s turned on.
Interference
The AD824 uses high-frequency digital circuits that may cause interference on radio
and television equipment located nearby. If interference is a problem, relocate the
affected equipment.

ing personal injury or any other damage caused by improper use or operation of the
