3. Preparing to Service
Electrostatic Discharge (ESD) Precaution
Servicing the machine exposes the control electronics
of the Janome machine. Take care to avoid handling
the open electronics as much as possible.
To minimize the risk of damage to the electronics due
to ESD, we recommend that you use an electrostatic
discharge mat and wrist strap.
To use an ESD-safe mat and wrist strap
1. Connect an ESD-safe mat to earth ground.
2. Place the machine on the ESD-safe mat.
Place the wrist strap on your wrist and connect it to
earth ground.
U
CAUTION
: Ensure all insulative materials (plastics, paper, etc.) are at least one foot away from the
work area.
U
CAUTION
: Ensure circuit boards are either mounted to the machine, in their ESD-safe packaging,
or placed directly on a properly grounded ESD-safe mat. Do not handle them until you are properly
grounded with an ESD wrist strap.
If an ESD wrist strap is not available, you should constantly discharge your body to earth ground by touching
a bare metal piece of the quilting machine, such as a thread guide at the top of the machine, the hopping
foot or take-up lever. Discharge repeatedly to the machine (every 20 to 30 seconds) while handling the circuit
board.
An ESD kit can be purchased from local electronics stores.
