Important Safety
Information

Please read these warnings before using your T2009 power
supply.

Warning: Safe Operation

To reduce the risk of fire or electric shock, please adhere to
these warnings:

■ Moisture: Do not expose this appliance to rain or moisture.

■ Cleaning: Unplug the power supply from the mains power

outlet before cleaning. Switching it off will not reduce this
risk.

■ Ventilation: Place the power supply in an area that will

allow air to flow freely around the unit. This will prevent the
power supply and mobile radio from overheating. Do not
block or obstruct any of the ventilation openings on the
unit.

Warning: Electrical Connections

To reduce the risk of fire or electric shock, please adhere to
these warnings:

■ Do not operate two or more units in parallel.

■ Your power supply should be properly connected and

grounded. Use the provided AC power cable to connect it to
a mains power outlet that is properly installed and
grounded, in accordance with all local codes and ordi­nances. If the power supply cord is damaged, it must be
replaced with the same type to comply with safety require­ments.

■ Never alter the provided AC cable or plug. If the plug does

not fit into the outlet, have a proper outlet installed by a
certified electrician.

■ Use an extension cord only when absolutely necessary. The

extension cord must have the same voltage and power rat­ing as the original power supply plug. Make sure that the

2 Important Safety Information

pins on the plug are of the same number, size and shape as
those of the original power supply plug.

■ Do not connect a backup battery directly to the power sup-

ply.

■ Do not use the power supply to directly charge a battery.

Warning: Servicing

This power supply should be serviced by a qualified servicing
technician. Incorrect assembly may result in electric shock or
fire. We recommended that you return your power supply to a
qualified Tait Electronics Ltd. dealer for any service or repair.

Warning: High Voltage Levels

Some of the components inside the T2009 operate at voltage
levels that may be lethal.

Important Safety Information 3

User Information

The T2009 power supply enables you to use your Tait T2000 or
Tait TM8000 mobile radio as a desktop radio.

The T2009 is a switched mode power supply. It converts mains
input voltage to regulated 13.8VDC, using pulse width modula­tion (PWM) control.

The T2009 power supply is protected against short circuits, as
well as over current and over voltage conditions.

Check the Mains Supply Voltage

Before you plug in and turn on your power supply the first time,
please check the mains supply voltage.

The voltage rating of the T2009 is printed on a label on the
bottom of the supply. Verify that it corresponds with your local
mains supply voltage (i.e. 120 VAC or 230 VAC).

The variations in mains supply voltage under which the T2009
can operate, are listed in the “Electrical Specifications” table on
page 17.

Turning the Power Supply on

The T2009 has an illuminated on/off switch, marked “I” for on
and “O” for off. Turn the power supply on by pressing the “I”
side of the switch. The indicator inside the switch will illumi­nate.

Note: If the T2009 does not turn on, refer to “Fault Finding

Information” on page 16.

Turning the Power Supply Off

Before you turn the power supply off, turn the radio off as
described in the user documentation for the radio.

To turn the power supply off, press the “O” side of the power
switch.

4 User Information

Cooling

The T2009 is cooled by convection cooling (normal airflow
around the power supply).

Place the unit in a well ventilated and cool area. Do not block
the ventilation openings on the sides, back or top of the unit.

Using the Microphone

Your radio can be programmed to activate or deactivate scan­ning or monitoring through the “hookswitch” feature. For more
information, refer to your radio’s user and programming docu­mentation.

Battery Charging

The T2009 should not be used as a battery charger.

Servicing

By following the procedures in this manual, and by exercising
normal care, your T2009 will give you trouble-free service for
many years.

However, when required, servicing should be carried out by a
qualified service technician. Within the warranty period, servic­ing must be carried out by your Tait dealer.

Installation Information

Caution: Install the T2009 indoors. It is not designed for

operation out-of-doors or in wet environments.
The installation of the T2009 and mobile radio is critical to its

performance. Tait authorised dealers are able to offer a prompt,
professional installation service.

The mobile radio can be operated at a distance from the T2009,
or it can be mounted on top of the T2009.

Note: When using a Tait radio in a desk top or despatcher

configuration (i.e. in conjunction with the T2009 at a fixed loca­tion), check the maximum legal transmit output power as
defined by the local regulatory authority (often in the range of 1
to 5W). Exceeding this output power may result in prosecution.
