Important Safety Warnings

There are several important safety notices to always keep in mind when using
the MS.
Many internal parts of the MS carry dangerous
voltages
If the MS is connected to a power source, even if the power switch is off,
potentially dangerous voltages exist on:
•
•
•
With the power switch on, potentially dangerous voltages also exist on:
•
•
•
All these parts are shielded by covers. With the covers in place, it should be
WAR N IN G
difficult to accidentally make contact with dangerous voltages. Unless
specifically instructed to, never remove a cover unless the detector, inlet, and
oven are turned off.
If the power cord insulation is frayed or worn, the cord must be replaced.

Electrostatic discharge is a threat to MS
electronics
The printed circuit boards in the MS can be damaged by electrostatic discharge.
Do not touch any of the boards unless it is absolutely necessary. If you must
handle them, wear a grounded wrist strap, and take other antistatic precautions.
