Operation

30

This product is equipped with a memory
backup system that preserves tuner presets
and system configuration information if
the unit is accidentally unplugged, turned
off completely with the 

1

for longer time or subject to a

power outage. This memory will last for
approximately two weeks, after which time
all information must be reentered.

In the rare case where the unit’s operation
or the displays seem abnormal, the cause
may involve the erratic operation of the
system’s memory or microprocessor.

To correct this problem, first unplug the
unit from the AC wall outlet and wait at
least three minutes. After the pause,
reconnect the AC power cord and check the
unit’s operation. If the system still
malfunctions, a system reset may clear the
problem.

To clear the AVR35RDS’s entire system
memory, including tuner presets, output
level settings, delay times and speaker
configuration data, first turn the unit off
by pressing and releasing the 

1

so that it pops out

from its normal recessed position. Next,
press and hold the 

$

and the

Ó

buttons while

pushing the 

1

in to turn the unit back on. Note that once
you have cleared the memory in this
manner, it is necessary to re-establish all
system configuration settings and tuner
presets.

If the system is still operating incorrectly,
there may have been an electronic
discharge or severe AC line interference
that has corrupted the memory or
microprocessor.

If these steps do not solve the problem,
consult an authorized Harman Kardon
service depot.
