APPENDIX D
PRODUCT SPECIFIC INFORMATION
for Digital Terminals Type MT512M
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 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 Amps @ 3Watts 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: 450 to 470 MHz
DMO: 450 to 470 MHz
Receiver Frequency Range:
450 to 470 MHz
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 terminal transmit and receive time (operating cycle time) is determined by the communi-
cation 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 reduc-
ing 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: 10A (Motorola Part Number: 65C80283E05)
Fuse for Ignition Sense Cable HKN9327: 4A (Motorola Part Number: 65C80283E02)
