MTM5400 Mobile Terminal Installation Manual
for Digital Terminals Type MT953C
In general, the terminal transmit and receive time
(operating cycle time) is determined by the
communication system. On overload, respectively on
extensive use beyond the systems specifications at high
ambient temperatures, the terminal is protected by its
thermal control, which cuts down the RF output power,
thus reducing the terminal coverage range.
