PRODUCT SPECIFIC INFORMATION
This section gives the Service Personnel an overview about product specific notes. This is neces-
sary to take special precautions to avoid the introduction of hazards when operating, installing, serv-
icing or storing equipment. This radio 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:
MT912 (380-430MHz): 3 Amps @ 3Watts RF power
MT712 (806-870MHz): 3.5Amps @ 3Watts RF power
Please be aware when planning the installation that there is a current consumption of approximately
30 mA even when the installed radio is switched off.
Transmitter Frequency Range:
TMO: 380 to 430 MHz (MT912); 806 to 825 MHz (MT712)
DMO: 380 to 430 MHz (MT912); 851 to 870 MHz (MT712)
Receiver Frequency Range:
380 to 430 MHz (MT912);
851 to 870 MHz (MT712)
Normal Load Conditions:
Rated RF Power: 3Watts
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
*Note: In general, the radio transmit and receive time (operating cycle time) is determined by the communica-
tion system. On overload, respectively on extensive use beyond the systems specifications at high ambient
temperatures, the radio is protected by its thermal control, which cuts down the RF output power, thus reducing
the radio coverage range.
Fuse Identification
In case of blown fuses during the installation only replace those with identically value. Never insert
different values.
