Product Specific Information
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: 3.5 Amps @ 10Watts RF power
Please be aware when planning the installation that there is a current consumption of approx. 3.5 A
during PTT and even 30 mA when terminal is switched off.
Transmitter Frequency Range:
TMO: 380–430 MHz (MT912M)
DMO: 380–430 MHz (MT912M)
Receiver Frequency Range:
380–430 MHz (MT912M)
Normal Load Conditions:
Rated RF Power: 10 Watts
Rated Audio Power: 13 Watts @ 4 Ohms; 6 Watts @ 8 Ohms
Antenna Impedance: 50 Ohms
Operating Temp. Range: -30 to +60°C
Operating Time*: Continuous / Intermittent
*Note: 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.
Fuse Identification
In case of blown fuses during the installation only replace those with identically value. Never insert
different values.
Fuse for Power Cable GKN6270/GKN6274: 10 A (Motorola Part Number: 6580283E05)
Fuse for Ignition Sense Cable HKN9327: 4 A (Motorola Part Number: 6580283E02)
Fuse for Y-Cable PMKN4133/PMKN4134: 2 A (Motorola Part Number: 65012023001)
