Distance/Danger Alert Lights The DDU controls system power, range for vehicle warnings, speaker volume, and all other system func- tions.
At the lower front edge of the DDU, a slot is provided to insert the optional driver’s identification card. Alert and indicator lights advise of multiple warning levels, system power, system failure, and, if so configured, failure of the driver to insert the identi- fication card. Fig. 2.24, Driver Display Unit, EVT-300 2. Push in the volume control and power ON/OFF knob to turn power on or off. Turn the knob left or right to increase or decrease speaker volume. Press and hold the knob for 5 seconds and then release it to activate the failure display mode. NOTE: The system may be configured to have no on/off capability and the volume may be con- figured to allow only some volume control.
A light sensor automatically adjusts alert and indica- tor light brightness depending on cab lighting condi- tions. A small speaker provides audible alert tones to warn of closing on an object ahead and, when equipped with an optional side sensor, of objects alongside when the turn signal is activated in prepa- ration for a lane change. Additional tones indicate speaker volume, system failure, driver’s card status, and data extraction pass or fail. 3. The speaker is located under the top cover of the DDU. It sounds audible tones to alert the driver to potential hazards. Volume may be re- stricted to a range above a minimum level. NOTE: This is a configurable electronic param- eter. 1.
The green power-on/driver’s card (optional) sta- tus indicator light illuminates when the system is activated and the power-on LED test is complete. If the system is configured to require that the driver’s card be read, and it is not, the ON light blinks continuously. 4. Rotate the range knob (if enabled) to change the first alert detection range from 3 to 2 seconds. This will also change the second alert detection range from 2 to 1.75 seconds. Push and hold the knob for 5 seconds to activate the accident re- construction function and freeze the most recent data in half of the allocated memory. 2.21
