Maintenance and Troubleshooting
Troubleshooting
Lower the volume of your sound system, and turn the K2600 off, then on again (this is called a
power cycle).
Press the +/-, 0, and Clear buttons (on the alphanumeric buttonpad) at the same time. This is
called a soft reset.
As a last resort, save to disk any RAM objects youÕve created, and perform a hard reset. Do this
by pressing the Master-mode button, then pressing the Reset soft button (at the lower right of
the display). The K2600 will warn you about deleting everything (only RAM objects will be
deleted). Press Yes. After a few seconds, the power-up display should appear.
Also check the suggestions on the following pages. If itÕs still not happening, the next step is to
shut off the power and call your dealer.
