We designed Take Control for minimal
maintenance. These instructions provide
you with steps that can keep it working for
many years to come.

Follow these steps for optimum perfor-
mance and longevity of your Take 
Control:

• Keep your Take Control away from small

children and pets.

• Do not drop your Take Control.

• Keep your Take Control away from heat

sources, such as heating registers or
direct sunlight.

• Keep your Take Control away from

liquids. Never immerse it in water. If
liquid should enter the unit, have it
examined by an authorized Harman
Kardon service center before using. See
“Technical Support” for more
information.

Occasional cleaning may be required, 
depending upon use.

To clean your TC1000:

1 Disconnect the TC1000 from your com-

puter, if connected.

2 Dampen a lint-free cloth with water,

mild detergent, or rubbing alcohol and
wipe the touchscreen, selector wheel,
buttons, and outer surfaces clean.

Take Control provides you with two levels
of low-battery indication: Low Battery and
Low Battery Warning.

A Low Battery indication appears as an

icon in the title bar on the touchscreen,
next to the time display. This icon appears
when batteries reach a level of 4.0 volts.
You can continue to operate the TC1000
when this icon appears.

A Low Battery Warning indication 
appears as an icon in the center of the
touchscreen. You will see this icon for four
seconds, before the touchscreen turns off.
This icon appears when batteries reach a
level of 3.8 volts. You cannot operate the
TC1000 with a Low Battery Warning.

If you receive a low-battery indication, 
replace all of your batteries with fresh AA
alkaline batteries. During replacement, en-
sure that all the batteries are oriented
properly in the battery compartment, 
observing the key – a vertical slot for the
battery tip – for the positive (+) end. If the
batteries are not inserted properly, the
TC1000 will not work.

Tip Keep the period short for the Display
time-out feature to extend the life of your
batteries.

• Keep batteries out of reach of children.

• Don’t mix old and new batteries, or

batteries of different types (for example,
carbon and alkaline 
batteries).

• Always remove old, weak, or worn-out

batteries promptly and dispose of them
in accordance with your local
ordinances. 

• If a battery leaks, remove all batteries

and dispose of them in accordance with
your local ordinances. Before inserting
new batteries, thoroughly clean the
battery compartment with a damp
paper towel, or follow the battery
manufacturer’s recommendations for
cleanup. If fluid from the battery comes
into contact with skin or clothes, flush
skin with water immediately.

• Remove the batteries if your system

controller is to be stored for longer than
a month without being used. 

The precautions below are to prevent the
sudden release of electrolytes, which these
prohibited actions can cause:

• Do not open, puncture, or mutilate the

batteries.

• Do not heat batteries in an attempt to

recharge them.

• Do not use a fire to dispose of batteries.

Released battery electrolyte is corrosive,
can cause damage to the eyes and skin,
and may be toxic if swallowed.
