PRODUCT SPECIFIC INFORMATION MTM700/MTM800 Mobile Terminal / Installation Manual Appendix - 81

APPENDIX

Product Specific Information

for Digital Terminals Type MT912/MT712 and MT912M

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, ser-

vicing 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 Curren:

MT912/MT912M (380-430MHz), MT512M (450-470MHz): 3 Amps @ 3 Watts RF power

MT712 (806-870MHz): 3.5 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 to 430 MHz (MT912/MT912M), 806 to 825 MHz (MT712), 450 to 470 MHz (MT512M)

DMO: 380 to 430 MHz (MT912/MT912M), 851 to 870 MHz (MT712), 450 to 470 MHz (MT512M)

Receiver Frequency Range:

380 to 430 MHz (MT912/MT912M), 851 to 870 MHz (MT712), 450-470 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*: Continous / 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 redu-

cing the terminal coverage range.

Fuse Identification

In case of blown fuses during the installation only replace those with identically value.

Nerver 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)
