Display Settings

This submenu lists available instrument types and display options. Units of measure are set in System Settings.

Mode Description: 'Normal' displays as usual. 'Reversed' flips the image upside down. 'HUD' reflects the image onto the windshield. 'Reversed HUD' is for when the display is facing downwards.

Vehicle Data Parameters

The display can show a wide range of vehicle data parameters:

LED Settings

The 10 full-colour LEDs above the screen act as status or alarm indicators. Their colour, direction, step interval, and alarm can be configured.

1. Enter the LED Settings submenu (Figure 11).
2. Edit the MODE field to select ALERT RPM or ALERT SHIFT.
3. Press [OK] to confirm.
4. Choose the STEP value (100, 200, 250, or 500 rpm) which defines the RPM increment for each LED change.
5. Select SHOW MODE or MULTICOLOR for how LEDs illuminate.

SHOW MODE:

• Direction: Left to Right (→) or Outside to Middle (→←).
• Interval Calculation: The LEDs remain dark until a start value is reached, then light up based on the chosen interval and direction. For example, with STEP 100 RPM, the start value is 1,000 RPM, and the range is 4,000 RPM.

MULTICOLOR:

• Set MULTICOLOR to ON.
• LEDs change colour as steps are reached, following a sequence (e.g., Green at 4,000 RPM, Red at 4,800 RPM, Flashing at 5,000 RPM).

DIMMER: Adjusts the colour gradation of the LEDs.

Vehicle Data Parameters (Detailed)

The display can show a wide range of vehicle data parameters:

Heads-Up Display (HUD) Function

The display information can be reflected off the inner windshield for easy reference without obstructing the view of the road. This function is best used at night due to limited lumen output.

1. Choose the display configuration you wish to view while driving.
2. Go to the configuration screen and select display settings.
3. Choose Mode, then select Reversed. The display will appear upside down.
4. Push the HUD unit (C) away until it is horizontal.
5. The display will reflect off the windshield. Adjust brightness so information is visible but does not interfere with driving.

Manual Wake Up Function

The unit can be manually started without the engine running, which is necessary for clearing DTC codes on some engines.

1. Turn the vehicle key to ON, but do not start the engine.
2. Press one of the four buttons to wake the unit from hibernation.
3. Press a button again within one minute to prevent re-hibernation.
4. To re-enter hibernation (or turn off while the engine is running), press one of the four buttons once after tasks are complete. The unit will hibernate in one minute.

Fuel Consumption Data

Accurate fuel consumption results require two factors:

1. Select the correct fuel type (Gasoline or Diesel) in System Setting – Fuel Type.
2. Fuel consumption calculation is based on airflow data or turbine/inlet pressure. Vehicles without these systems may not display correct consumption.

Care & Maintenance

1. Maintain the tool with care for efficiency and fewer problems.
2. Periodically inspect components; repair or replace damaged parts with identical replacements.
3. Keep tool labels and name plates intact. Contact Princess Auto Ltd. for replacements if unreadable or missing.

WARNING! Only qualified service personnel should repair the tool. Improper repairs may pose a hazard.

Disposal

Recycle damaged tools at an appropriate facility. Contact your local municipality for disposal regulations regarding electronics, batteries, oil, and toxic liquids.
