Precautions
1. Warranty Card
The serial number is written on the rear panel of this unit. Copy
the serial number and model number onto your warranty card
and keep it in a safe place.
2. Recording Copyright
Recording of copyrighted material for other than personal use
is illegal without permission of the copyright holder.
3. AC Fuse
The fuse is located inside the chassis and is not user serviceable.
if power does not come on, contact your Onkyo service center.
4. Care
From time to time you should wipe off the front and rear panels
and the cabinet with a soft cloth. For heavier dirt, dampen a soft
cloth in a weak solution of mild detergent and water or a mild
ammonia cleaner, wring it out dry, and wipe off the dirt. Fol-
lowing this, dry immediately with a clean cloth. Do not use rough
maternal, thinners, alcohol or other chemical soivents or cloths
since these could damage the finish or remove the panel lettering.
Memory Preservation
This unit does not require memory preservation batteries. A
built-in memory power back-up system preserves the contents
of the memory during power failures and even when the unit
is unplugged. The unit must be plugged in and the power switch
turned on and off once in order to charge the back-up system.
Note that since this is not a permanent memory, the power switch
must be turned on and off a few times each month to keep the
back-up system operative.
The memory preservation period after power has been turned
off varies depending on climate and placement of the unit. On
the average, memory contents are protected over a period of a
few weeks after the last time power has been turned off. This
period is shorter when the unit is exposed to a highly humid
climate.
