3.9 Physical Specifications (in Tray)
The TX56/56A and TX57/57A are the same size and weight.
Specification Characteristics
Height 33 mm (1.30”)
Width 159 mm (6.25”)
Length 231 mm (9.1”) behind the panel
274 mm (10.78”) overall
Weight (including all supplied
installation accessories) 1.26 kg. (2.78 lbs)
3.10 Low Voltage Operation
Normal operating voltage for the TX56 is any voltage between 11 and 33
volts, whilst normal operating voltage for the TX57 is any voltage between 22
and 33 volts. At these voltages all functions behave normally, and transmitter
power meets the applicable Class requirements of ED-23C.
The radio will continue to operate at a lower voltage than these ranges. As the
available voltage falls, the transmitter output power will be reduced, and at 9
volts the nominal transmitter power will be approximately 2.5 watts. The
transmitter will be inhibited below 8 volts.
The receiver also works below the nominal voltage. All receiver functions will
work normally, but as a safety feature to preserve battery power in an
emergency, at 10 volts or below the available speaker volume will reduce.
In addition a warning message, “Low Volt”, will be displayed on the screen
when the bus voltage falls below 10 volts in a TX56, or 18 volts in a TX57.
