Operation and handling
Do not remove the controller or HT1 covers, and do not attempt to disassemble or
modify them.
Doing so could result in fires or equipment failure.
Do not touch or operate the controller or HT1 with wet hands.
Doing so could result in electrical shocks or equipment failure.
Immediately turn off the power if abnormal odors, sounds, or smoke are noticed
during operation.
Failing to do so could result in electrical shocks, fires, or equipment failure. Stop operation
immediately, and contact your YAMAHA representative.
•
Maintenance and inspection
Perform maintenance and inspection tasks only when instructions for doing so are
provided by YAMAHA.
Maintenance and inspections performed by a person who lacks the proper knowledge or
training is extremely hazardous.
Shut off the power to the controller before performing inspections and maintenance
tasks.
Shut off the power and wait at least 10 minutes before beginning the tasks.
Failing to do so could result in electrical shocks or burn injuries from touching areas which are still
hot or from touching components where a high-voltage condition remains for a short period after a
power OFF.
Use the controller and robot only in the prescribed combinations.
Unsuitable combinations could result in fires and equipment failure.
Save the controller's internal data to an external memory device.
The controller's internal data could be unexpectedly lost, and should therefore be backed
up to an external device.
Do not use solvents such as thinner, benzene, or alcohol, etc., to wipe (clean) the
HT1 surfaces.
Doing so can cause the surface sheet and printing to peel off, and can cause equipment
failure. The HT1 surface should be gently wiped with a soft, dry cloth.
Do not use a hard or pointed object to operate the HT1 keys.
Doing so could scratch the keys and cause malfunctions and equipment failure. The HT1
keys should be operated with the fingertips.
