APPENDIX
Product Specific Information
for Digital Terminals Type MT912M/MT812M/MT712M/MT512M
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. All operating and safety instructions are to be followed carefully.
Equipment Electrical Ratings
Rated Voltage: 12 Volt DC
Rated Voltage Range: 10.8 to 15.6 V DC
Rated Current:
MT912M (380-430 MHz), MT812M (350-390 MHz), MT512M (410-470 MHz),
MT712M (806-870 MHz): 3 Amps @ 3 Watts RF power
Please be aware when planning the installation that there is a current consumption of approx. 3.5A
during PTT and even 30mA when
terminal is switched off.
Transmitter Frequency Range:
TMO: 380-430 MHz (MT912M), 350-390 MHz (MT812M), 806-825 MHz (MT712M),
410-470 MHz (MT512M)
DMO: 380-430 MHz (MT912M), 350-390 MHz (MT812M), 851-870 MHz (MT712M),
410-470 MHz (MT512M)
Receiver Frequency Range:
380-430 MHz (MT912/MT912M), 350-390 MHz (MT812M), 851-870 MHz (MT712/MT712M),
410-470 MHz (MT512M)
Normal Load Conditions
Rated RF Power: 3 Watts
Rated Audio Power: 10 Watts @ 4 Ohms; 6 Watts @ 8 Ohms
Antenna Impedance: 50 Ohms
Operating Temp. Range: -30 to +60°C
Operating Time: Continuous/Intermittent
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.
