3.6 Low Voltage Operation
Normal operating voltage for the TY96 is any voltage between 11 and 33 volts, whilst normal
operating voltage for the TY97 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
