Preventive Maintenance
With a modicum of care, your K2600 will give you years of use and enjoyment. There are just a
few important points to keep in mind.
Proper installation is essential to the health and welfare of your K2600. Keyboard models should
always rest on a hard ßat surfaceÑand on its rubber feet, not on the bottom panel. Rack models
should be mounted in a standard 19-inch MIDI rack, or should rest on a hard ßat surface. In this
case it must rest on its rubber feet, and not on the bottom panel.
Never block the ventilation openings; doing so can cause overheating that will seriously damage
your K2600. To provide adequate ventilation, the rear panel should be at least four inches from
any vertical surface (for both keyboard and rack models). Try to minimize the amount of dust in
the environment.
The K2600Õs RAM backup battery, along with any PRAM, sample RAM, or ROM block options
you may install, are the only user-serviceable parts in the K2600. The only part you should ever
disassemble on your K2600 is the access panel on the bottom of the instrumentÑremoving
anything else will void your product warranty.
Cleaning Your K2600
ItÕs a good idea to remove dust from your K2600 occasionally. You may also want to remove
Þngerprints. You can clean the K2600Õs front panel with a soft damp cloth, and use a mild soap
or detergent. Never use strong cleaners or solvents, and never spray anything on the front panel
or into the ventilation holes. Any cleaners you may want to use should be applied to your
cleaning cloth; you can then carefully wipe the surfaces of the K2600.
Floppy Disk Drive Maintenance
As long as youÕre reasonably careful to keep dirt and dust out of the ßoppy disk drive, you
shouldnÕt have any problems. If, however, you start to experience errors or failures in loading or
saving, it may be due to dirt in the ßoppy drive mechanism. See your dealer for information
regarding products and techniques for ßoppy drive cleaning.
