Troubleshooting
Maintenance
Aside from normal care in handling and use, your KME61requires no regular maintenance.
Clean with a soft cloth dampened with water. Never use abrasives or solvents as they may
damage the unit’s paint, markings, and display lens. There are no batteries inside to
replace-ever. Instead of volatile SRAM used in most other instruments, your KME61 uses
nonvolatile EEPROM for storage, which retains information as captured electrons, without
power.
Common Problems
Below is a list of the most commonly encountered problems and suggestions for solving them.
Power Problems
The LCD and LEDs will display a short startup sequence when power is turned on then
begin normal operation. If nothing at all happens when you turn the power switch on (solid
line “|” pressed in), check these items:
• Power module not plugged securely in wall outlet.
• Cord from power module not fully plugged into KME61.
• Input voltage rating of power module does not match your power system.
• Incorrect or defective power module. The power module specifications are:
9.5VAC, 2.0 amp, center pin positive, 5.5mm OD, 2.5mm ID coax type plug
(Kurzweil Model No. PP95-20).
• Dead wall outlet, power strip, or extension cord.
If there’s evidence of life but operation isn’t quite normal, check these items:
• Input voltage rating of power module does not match your power system.
• Incorrect or defective power module. See above for power module specs. Voltage
or current rating less than specified will cause unusual or intermittent operation.
• Power system voltage abnormally low. Try a different, unused outlet.
• Intermittent operation can be caused by a replacement power module with the
wrong size plug. The correct plug fits snugly into the jack, and doesn’t wobble.
