The Micro Tube Extreme Range (MTER) traffic signal preemption transmitter can be mounted in virtually any location on an emergency vehicle. The waterproof design permits exposure to the harshest environments including engine compartment and light bars. For mounting locations that expose the MTER directly to weather or excessive moisture, weather tight connectors should be used. The MTER has a removable mounting plate. When installed with the mounting plate, self tapping sheet metal screws are provided, or use 8-32 machine screws, lock washers and nuts for through bulkhead mounting.

Modes of operation. The MTER has several modes of operation, they are:

Extreme Range Mode. Provides an average range of 2500 feet.  Always enabled.

Disable Mode. Disables the strobe emitter when the user activates one the disable inputs.

Diagnostic Mode. When wired correctly, the diagnostic mode gives the user feedback on the MTER's operating condition. For more information see Self Diagnostics.

High Temperature Disable Mode. This operating mode disables the emitter when the internal temperature of the MTER gets too high for normal operation and to prevent damage to the unit. Once the unit cools down, the unit will resume operation.
