Keyswitch
Maintenance
The keyswitches are "self-wiping" which means that they are
automatically cleaned with each movement. At the end of their
travel, the switches move a bit
farther'
and this dragging motion
cleans the contact.
The keyswitches
should not be cleaned with any abrasive
material or solvent. They may
be
gently sprayed with compressed
air.
