Left MIX output seems louder than Right MIX output when used individually.
1 This is normal. When a cable is plugged into the left MIX output alone,
both the left AND the right audio signals are routed to the jack. When a
cable is plugged into right MIX output alone, only the right channel audio
signal is heard.
Volume knob has no effect.
1 Separate outputs are in use - the volume knob does not affect the separate
outputs.
2 MIDI volume has been assigned to a control source which has sent a value
of 0.
Programs, Setups, Songs, etc. are missing.
1 Batteries have run down or have been disconnected. If the batteries have
failed, the message ÒBattery voltage is low - X.X voltsÓ (where X.X is less
than 3.0) will appear in the display on power-up. All user data will be per-
manently lost if this occurs. See the information on battery selection and
replacement elsewhere in this manual.
LCD is too dark or too light to read.
1 Contrast not adjusted. Select Master mode and adjust the Contrast param-
eter. If this fails, hold the ENTER button and turn the alpha wheel clock-
wise to make display darker; counterclockwise to make it lighter. Then
adjust the Master mode Contrast parameter to a higher value if the LCD
was too light, or to a lower value if it was too dark.

3 You have instructed the K2vx to format a Double density (720K) disk as a
high-density (1.4M) disk. NOTE: Punching a hole in a double-density disk
case to try to make the K2vx read it as a high-density disk is not recom-
mended.
