MV3 - manual

The LED number display MV3 variant, is a double display screen for presenting the rounds completed in sports as well as a score board for balls and baskets.
The numbers on the upper part of the board are usually displayed with white LEDs whereas those in the lower part are displayed with red LEDs. The numbers 0 to 99 and blank can be displayed on both board halves.
The number display is operated via an integrated key field in the lower part of the display or via the provided remote control. 
When the case is open, its size is 460 x 560 x 26 mm, the numbers (230 x 160 mm each) are clearly readable even from a distance of 80 m. The numbers can be easily seen even under poor lighting conditions. This is ensured by means of the PLCC4 SMD-LEDs with a viewing angle of 170° and an intensity of 1400 – 2200 mcd. A special acrylic filter ensures excellent aperture and reflection-free display of the numbers. Its surface is scratch-resistant.
Silver pure-anodized aluminium profiles and laminate surface with a brush structure present the aluminium box with an elegant design.When the case is closed, it is extremely compact (460 x 290 x 52 mm) and very rugged.

The „+“ (plus) key increases the numeric value by one and the „-“ (minus) key decreases it by one.
If any of the four keys are is pressed for more than 1.5 seconds, the display starts changing at a speed of 10 numbers / sec. The display value is saved every 2.5 seconds after any change so that the last display value is displayed after the MV3 is restarted via the “Power” key.
