The display is very clear and can be easily read up close and from far away. The LEDs are bright but not overpowering and so do not consume much electrical power.

Messages can be sent to the display using a Bluetooth enabled Phone, Tablet or Computer.

The display is set up using simple commands sent from via the Bluetooth connection. Messages can be set to display once or repeat multiple times or even go on forever until a new message is received. The text scroll speed can also be altered. The colour of the display can be set to a fixed RGB colour or can be randomly generated as each new message is displayed. An audible beep can also be enabled whenever a new message is received to attract people’s attention to the display.

The unit is supplied with:

• 10 x 7 LED Array Unit With Bluetooth functionality
• USB cable power supply
• Instruction Manual

The unit requires a 5V power supply and can be powered from a USB socket or USB charger using the provided cables. Alternatively a compatible 5V 2.1mm DC UK main adapter is available separately.

The rear of the unit has holes to allow the display to be mounted onto a wall. The front of the unit has holes to allow the display to be mounted onto a window using small suction cup hooks.

The dimensions of the unit are 194mm x 145.5mm x 23.4mm.
