My Safescan 155 doesn't power on immediately, is it faulty?

The Safescan 155 powers on after pressing the on/ off key for a few seconds. Another thing to check is to find out if the adapter is faulty. In case you have a spare one please try using this one first.

Note: from firmware version S21-51 onwards: pressing on/off key for 1 second will power on the device.
