As soon as the Mobile KeyReader Plus 2 is connected with the power supply, the device turns on
automatically and the charging process starts. The LED with the battery icon informs the user about
the charge state of the battery. (Once the battery is fully charged, the LED turns green if the cable is
connected.)
Please note that a fully charged battery keeps the device ready for operation for approximately 10
hours. The USB port of a PC might not provide permanent power to charge the Mobile KeyReader
Plus 2. To make sure that the device is ready for operation in the morning, it should be charged over-
night with the provided power pack. Connection to a PC is only recommended for configuration of the
Mobile KeyReader Plus 2.
If the Mobile KeyReader Plus 2 is not used over longer periods, it should be switched off. Please note
that the Mobile KeyReader Plus 2 turns on by itself if the USB cable is connected and cannot be
turned off. Therefore, the device should not be connected to a USB port in case of longer interruptions
of operation to prevent unintended reactivation.
If the Mobile KeyReader Plus 2 should be completely discharged, it may happen that the device can-
not complete its boot process (indicated by the blue flashing LED. In this case, the device has to be
charged completely with the provided power pack for approximately 8 hours.
Display and operating elements
The Mobile KeyReader Plus 2 features 3 multi-coloured LEDs that inform the user about the current
operating status. The LEDs all have an underlying symbol. There is an LED for the key reading func-
tion (symbol: key), one for the connection status to the server (symbol: waves), and one for the battery
status (symbol: battery). Section 3 contains a detailed description.
The contacts for the charging cradle are located on the opposite end, and a micro USB connection as
well as a switch are safely located beneath a slider. The switch can be operated with a pointed object.
The Mobile KeyReader Plus 2 can be turned on and off with the switch. For turning the device off, the
switch must be actuated for at least 2 seconds. Once you let go of the switch, the Mobile KeyReader
Plus 2 switches into standby mode. This is signalled by a flashing blue LED.
If you want to return the Mobile KeyReader Plus 2 to the factory settings, press the switch for at least
10 seconds while the device is turned on. A so-called "factory reset" takes place. With this reset, all
key data and settings are deleted.
The micro USB port is redundant for connecting the Mobile KeyReader Plus 2 via the charging station.
The Mobile KeyReader Plus 2 can be charged and configured via this port.
