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 mois-
ture.
■Cleaning: Unplug the power supply from the mains
power outlet before cleaning. Switching off the power
supply 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 connect two or more power supplies together.
■The power supply should be properly connected and
grounded. Use the provided AC power cable to connect
the power supply 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 dam-
aged, it must be replaced with the same type to comply
with safety requirements.

Important safety information 3
■Never alter the provided AC cable or plug. If the plug
does not fit into the outlet, have an appropriate 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 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
supply.
■Do not use the power supply to directly charge a battery.
Warning: Servicing
This power supply should be serviced by a qualified service
technician. Incorrect assembly may result in electric shock or
fire. We recommend that you return the power supply to a
qualified Tait Electronics Ltd dealer for all services and
repairs.
Warning: High voltage levels
Some of the components inside the T2009 operate at voltage
levels that may be lethal.

4User information
User information
The T2009 power supply enables you to use your Tait T2000
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 the power supply for 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 power supply. Verify that it corresponds with
your local mains supply voltage (that is, 120VAC or 230VAC).
The variations in mains supply voltage under which the
T2009 can operate, are listed in the “Electrical specifica-
tions” table on page 16.
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 “Troubleshoot-
ing” on page 15.
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.

User information 5
To turn the power supply off, press the “O” side of the power
switch.
Cooling
The T2009 is cooled by convection cooling (normal airflow
around the power supply).
Caution: 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 the user and programming
documentation for your radio.
Servicing
By following the procedures in this user’s guide, and by exer-
cising normal care, theT2009 will give you trouble-free serv-
ice 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.
Note: When using a Tait radio in a desktop or despatcher
configuration (that is, 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.

6User information
The correct installation of the T2009 and mobile radio is crit-
ical to its performance. Tait authorised dealers are able to
