8. Troubleshooting
Please take note of our advice on installing the unit at the beginning of this manual. The following factors may have adverse ef-
fects on the performance of your mbl 1621 A:
• excessively high temperature (over 40° C, e.g. near heating appliances)
• low temperature (below 10° C)
• extreme humidty (over 95 %, e.g. near air conditioners)
• extremely dry air (humidity below 10 %)
• extreme temperature variations (condensation)
• dust
• electrostatic interferences (e.g. near fluorescent lamps or engines)
• vibration and shock
These external influences should be addressed first, if problems occur.
No power, no display
Has the plug been properly connected to the wall outlet? Has it been properly attached to the transport itself? It may sound
strange, but the latter problem occurs more often than one cares to count. Insert the plug securely into the wall outlet and the
transport connector.
Is the wall outlet working correctly? Connect a different electric appliance to the wall outlet and see if it works.
If the plug is properly attached and wall outlet working correctly, check the fuse:
• Always pull the plug from the wall outlet first! Otherwise, you will risk damage to the transport. DANGER - health ha-
zard!
• Pull out the fuse holder, which is installed above the power connector on the back panel.
• The fuse holder contains 2 fuses (0,5 AT for 230 V/A or 1,0 AT for 115 V/A). The left fuse is the active one, the right one
is in reserve. Exchange both fuses.
• Put the fuse holder back in place and re-plug the transport to the wall outlet.
If the transport still does not work, pull the plug again and wait for at least 3 hours. If condensation has formed inside the cabi-
net, this waiting period should allow the transport to dry out. Plug in the transport again afterwards. If it still does not work, you
should consult a qualified engineer.
