INSTALLING BATTERIES

In the System

Cautions:

• Always use fresh batteries of the
required size and recommended
type.

• Never leave dead or we ak batter­ies in the system or remote con­trol. Batteries can leak chemicals
that can corrode the control.

1. Press in on the battery compart­ment cover and push in the direc­tion of the arrow, and lift off the
cover.

illustration

2. Put two AA batteries in the com­partment as indicated by the po­larity symbols (+ and –) marked
inside.

3. Replace the cover.

In the Remote Control

The remote control requires two AA A
batteries (not supplied) for power. We
recommend alkaline batteries, such
as RadioShack Cat. No. 23-555 for
the best performance and longest life.

1. Press the tab in the direction of
the arrow and lift off the battery
compartment cover.

• Do not mix old and new batteries,
different types of batteries (stan­dard, alkaline, or rechargeable),
or rechargeable batteries of differ­ent capacities.

To retain any preset radio stations
during an AC power loss, install two
alkaline AA batteries (such as Cat.
No. 23-557) into the system’s battery
compartment.

3. Replace the cover.

Caution: If you are n ot going t o use
the remote control for a month or
more, remove its batteries. Batteries
can leak damaging chemicals.

You can use the remote control up to
a distance of a bout 20 feet from the
System 746. If the remote control
operates erratically or does not
work, replace both batteries.

• Connecting headphones auto­matically disconnects the speak­ers.

• Your local RadioShack store
sells a wide selection of head­phones.

Listening Safely

To protect your hearing, follow these
guidelines when you use head­phones.

• Do not listen at extremely high
volume levels. Extended high­volume listening can lead to per­manent hearing loss.

• Set the vol ume to the lowest set­ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable
level.

• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not
cause discomfort might still
damage your hearing.
