The device is activated by pressing the red <ON> button.
Upon initial activation, the green "On LED" lights up. It takes 30-50
seconds until all programs are initialized. Only then does the main screen
appear as shown at right.
Once the REA ScanCheck 3 has been activated, it can be deactivated by
pressing the <ON> button again.The display then opens the menu window
for various modes.
The colored focus can be moved to the desired command with the arrow
keys and then confirmed with the <OK Enter> button.
The digit in front of the menu item can also be activated by pressing the
corresponding number button <1...6> and thereby immediately initiating the
desired function.
1. Sleep Mode
Sets the unit to a power-saving sleep mode in which the display
and other drivers are deactivated and the processor continues to
operate at the lowest power consumption.
It can be immediately reactivated from this mode by pressing the
<ON> button. The sleep mode should be activated automatically
via the unit settings after a pre-specified time in order to save
power in rechargeable battery mode.
2. Shut down device

should select this function when the unit will not be used for an
extended period, such as at the end of measurements or work day.
A minor amount of energy is also required from the rechargeable
batteries or power supply in this operating mode.
3. Reboot device
A restart of the complete system can be carried out with this menu
item. Executing this command can be helpful if the unit no longer
responds as expected.

interface. Execution of this command is only useful for service
purposes.

responds only to corresponding text commands.
