Product Specific Information for Digital Terminals Type MT953C

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:

MT953C (380-430 MHz): 4 Amps @ 10 Watts RF power

Please be aware when planning the installation that there is a current consumption of approx. 4.5A during PTT and even 30mA when terminal is switched off.

Transmitter Frequency Range:

TMO: 380-430 MHz (MT953C)

DMO: 380-430 MHz (MT953C)

Receiver Frequency Range:

380-430 MHz (MT953C)

Normal Load Conditions

Rated RF Power: 10 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.
