Installing the Intellifont Proms
M WARNING! Turn off the printer and unplug the power cord before
taking the cover off the printer.
ACHTUNG! Bitte schalten Sie den Drucker aus und ziehen Sie den
Netzstecker heraus bevor Sie die Druckerabdeckung öffnen.
▲ Caution: It's very important to protect the printer controller board from
electrostatic damage while performing this task.
If an anti-static wrist strap is provided in your printer option kit,
attach one end of it to your wrist and the other end to any convenient
electrical ground (for example, the bare metal chassis of equipment,
as on the back of a computer, that is plugged in but
turned off ). Never
attach the wrist strap to any piece of equipment with an electrical
current present. Turn off all power switches first. Plastic, rubber,
wood, painted metal surfaces, and telephones are not acceptable
grounding points. The printer isn't an acceptable grounding point
either because it must be unplugged before you perform this task.
