Maintenance and Troubleshooting
Preventitive Maintenance
With a modicum of care, your K2vx 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 K2vx. It 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 on the rear
panel; doing so can cause overheating that will seriously damage your K2vx! To provide
adequate ventilation, the rear panel should be at least four inches from any vertical surface. If
you install an internal hard disk, the ventilation opening on the underside of the K2vx must
remain unobstructed so the cooling fan can operate properly. Care should be taken to minimize
the amount of dust in the environment.
There are no user-serviceable parts in the K2vx. Under no circumstances should you attempt to
remove any panels (except for battery replacement). If you attempt to open your K2vx, youÕll
risk electric shock, and youÕll void your product warranty.
Cleaning your K2vx
ItÕs a good idea to remove dust from your K2vx occasionally. You may also want to remove
Þngerprints. You can clean the K2vxÕs 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 K2vx.
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.
Battery selection and Replacement
The K2vx uses batteries to preserve its internal memory when the power is turned off. The
original batteries should last up to two years before they need replacing. Replacement is
necessary when the LCD says ÒBATTERY VOLTAGE IS LOWÓ during power-up, or when you
notice that the LEDs ßash three times instead of once during power-up. Once these warnings
begin to occur, the batteries should be replaced within a couple of weeks to ensure continued
safety of your RAM objects.
To replace the batteries, youÕll need access to the rear panel. Remove the battery compartment
cover, which is located at the lower right corner of the rear panel as you face it. You may wish to
use a small screwdriver. Replace the batteries with three high quality AA size Òheavy dutyÓ or
alkaline batteries. A capacitor will keep the memory alive for about 30 seconds while changing
the batteries, so donÕt remove the old ones until the new ones are available. Alternatively, it is
permissible to have the power cable plugged in and the power on while changing the batteries,
in which case memory will be retained as long as power is on. Be sure to insert the new
