ROUTINE MAINTENANCE

The bulleted items below describe routine maintenance that should

be performed on a periodic basis.

•

Clean the AV2 exterior surface with a soft, lint-free cloth. Do

not use alcohol, benzene, acetone-based cleaners or strong

commercial cleaners. Do not use a cloth made with steel wool

or metal polish. If the AV2 is exposed to a dusty environment, a

low-pressure blower can be used to remove dust from its

exterior surface.

•

Replace the remote control batteries as needed. The remote

control requires four AAA batteries. When these batteries are

low on power, the remote control enters a low-voltage

condition that prevents it from operating the AV2. Normal

operation will resume when new batteries are installed.

Note: The remote control will not lose any custom settings if the

batteries run out. All custom settings are stored in nonvolatile FLASH

memory. 

RESTORING FACTORY DEFAULT SETTINGS

It is possible to reset the AV2 processor to its factory settings.

However, doing so will permanently delete any user-defined or

manually-entered settings, including parameters such as speaker

setup changes and input names.

Before per for ming a factor y reset, be sure to use the

worksheets in Appendix D to record all of the input and setup

information. The factory reset WILL delete all custom settings

except for the saved EQ Presets.

To restore the factory default settings:

1. Record all parameters and user-defined settings on the

Installation Worksheet that begins on page D-2. 

2. Put the AV2 into Standby.

3. Press and hold the MUTE and ZONE 2 AUX 1 buttons at the

same time.

After several seconds, the AV2 will turn on. The front panel display

will state “RESET” and then it will return to the normal display. All

parameters and user-defined values will now reflect the factory

default settings, with the exception of any saved EQ Presets.

Note: If you want to save your settings before restoring the factory

defaults, you must record them manually. The Installation Worksheet in

Appendix D has been provided to assist you.
