Troubleshooting

Should the MBWBLUE not work as described in this document, please check the list
of possible error causes below for a solution:
• After pressing the On button there is no LED lit up.
o Charge the device for at least 4 hours.
o If the error persists, turn the device in for repair.
• After having dropped the MBWBLUE device to the ground it is no longer
possible to switch it on (there is no LED lit up after pressing the On button).
o Connect the charger for approximately 15 seconds. Try to switch on the
device again.
o If the error persists turn the device in for repair.
• After connecting the battery charger the PWR LED is not lit up.
o Check if the plug of the battery charger is correctly placed onto the
MBWBLUE connector.
o Check if the battery charger wall plug is connected to mains power
supply.
o If the error persists turn the device in for repair.
• It is not possible to establish a Bluetooth connection.
o Check if the MBWBLUE is still switched on.
o Check if the MBWBLUE was found during the Bluetooth device search
and repeat it, if necessary.
o Switch the MBWBLUE off (by holding the On button down for more than
5 seconds), wait 60 seconds and switch it on again. Retry the Bluetooth
search then. Note, that it is not possible to switch off the device
manually if a Bluetooth connection is established (Bluetooth LED lights
up in amber).
o Switch off and restart your computer.
o Try another computer for establishing the Bluetooth connection.
o If the error persists turn the device in for repair.
• The battery operating time is much shorter than specified.
o If you are using the serial interface intensively with an external device
consuming a lot of power, the battery operating time is shorter than
specified. This depends on the power consumption of the external
device and on how long the external device is switched on.
o Lithium ion batteries are degrading with time and charging cycles.
Usually, after one year or 300 charging cycles the capacity should be
still at 80% of the initial capacity. However, if the battery operating time
becomes too short after several years, it is possible to replace the
lithium ion battery. Do not attempt to replace the battery by yourself but
turn the device in.
