Product Specific Information for
Digital Terminals Type MT953CG
This section gives the Service Personnel an overview about product-specific notes. This is necessary
to take special precautions to avoid the introduction of hazards when operating, installing, servicing, or
storing equipment. This terminal meets the applicable safety standards if it is used as described.
Follow carefully all operating and safety instructions.
Table 71: Equipment Electrical Ratings
Rated Voltage 12 VDC
Rated Voltage Range 10.8 VDC to 15.6 VDC
Rated Current MT953CG (380–430 MHz): 4 A @ 10 W RF power
Please be aware when planning the installation that there is a maxi-
mum current consumption of 4.5 A during PTT and even 30 mA
(non-Ethernet)/ 90 mA (Ethernet) when terminal is switched off.
Transmitter Frequency
Range TMO: 380–430 MHz (MT953CG)
DMO: 380–430 MHz (MT953CG)
Receiver Frequency
Range 380–430 MHz (MT953CG)
Table 72: Normal Load Conditions
Rated RF Power 10 W
Rated Audio Power 10 W @ 4 Ω; 6 W @ 8 Ω
Antenna Impedance 50 Ω
Operating Temp. Range -30°C to +60°C
Operating Time Continuous/Intermittent
NOTICE: In general, the communication system determines the terminal transmit and receive
time (operating cycle time). On overload, respectively on extensive use beyond the systems
specifications at high ambient temperatures, the thermal control protects the terminal. The
thermal control cuts down the RF output power, thus reducing the terminal coverage range.
