TMAA13 User’sGuide
The variations in mains supply voltage under which the TMAA13
power supply can operate, are listed in the
‘Electrical specifications’
on page 8
.
Turning the power supply on
The power supply 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.
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.
Cooling
The TMAA13 power supply is cooled by convection and forced air
cooling (that is, normal airflow around the power supply in
combination with a temperature controlled fan to improve cooling at
higher levels of use). The fan is activated by a sensor when the
temperature rises above 70°C.
Caution:
Place the power supply in a well ventilated and cool area.
Do not block the ventilation openings on the sides, back or top of the
unit.
Servicing
By following the procedures in this user’s guide, and by exercising
normal care, the power supply will give you trouble-free service for
many years. However, when required, servicing should be carried out
by a qualified service technician. While within the warranty period,
servicing must be carried out by your Tait dealer.
