Caution
Risk of damage to the unit!
Switch the unit off before connecting the parallel printer to the LPT1 port.
(The printer should also be switched off.)
Make sure you use the right interface port. If you use the wrong port, the
printer or PG 740 may be damaged.
The interface port may be damaged if you reverse the polarity of the
connections or use the wrong connecting cables.
Before plugging in the cables, you must discharge the electrostatic charge in
your body and the connecting cables by briefly touching a grounded object
(ESD guideline). Only use original connecting cables.
