Product Specific Information for Digital
Terminals Type MTC953DE
This section gives the Service Personnel an overview about product-specific notes. It 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 99: Equipment Electrical Ratings
Parameter Value
Rated Voltage 12 VDC
Rated Voltage Range 10.8 VDC to 15.6 VDC
Rated Current MTC953DE (350–470 MHz): 5.5 A at 10 W RF power.
Please be aware when planning the installation that there is
a maximum current consumption of 10.5 A during PTT and
even 100 mA (non-Ethernet)/ 90 mA (Ethernet) when terminal
is switched off.
Transmitter Frequency Range
TMO 350–470 MHz
DMO 350–470 MHz
Receiver Frequency Range 350–470 MHz
Table 100: Normal Load Conditions
Parameter Value
Rated RF Power 10 W
Rated Audio Power 13 W @ 4 Ω, 15.6 W @ 4 Ω
Antenna Impedance 50 Ω
Operating Temp. Range -30 °C to +60 °C
Operating Time Continuous/Intermittent
NOTE: In general, the communication system determines terminal transmit and receive time (operating
cycle time). On overload, respectively on extensive use beyond the system 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.
