Output Level Trim Adjustment
Normal output level adjustment for the
AVR45 is established using the Test Tone,
as outlined on page 19. In some cases,
however, it may be desirable to adjust the
output levels using program material
such as a test disc, or a selection you are
familiar with. Additionally, the output
level for the subwoofer may only be
adjusted using this procedure.
To adjust the output levels using pro-
gram material, first set the reference
volume for the front left/right channels

ory will last for approximately two weeks,
after which time all information must
be reentered.
Processor Reset
In the rare case where the unit's opera-
tion 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 AVR45's entire system
memory, including tuner presets, output
level settings, deley times and speaker
configuration data, first turn the unit off
by pressing and releasing the
so that it pops out

press and hold the

buttons while

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.
