Tecnodent Sting Manual De Instrucciones página 36

The chair does not move at all, even if
the main switch is switched on and the
mains group is working correctly.
The chair moves properly in all manual
movements, but it is impossible to store
working position programs.
Chair movement testing procedure
Do you hear a "CLICK" sound when you
try to activate the controls?
Does the motor hum?
It is impossible to determine the cause of
the failure unless further and more com-
plex testing is applied. Call the servicing
technicians.
Chair programming control procedure (only for chairs with programs)
Was the programming procedure prop-
erly applied? (see paragraph 4.3.2 for
reference)
Did you hear a "BEEP" sound when the
programming procedure was completed,
to confirm the programs' saving?
The PCB has probably failed. Call the
technical service.

Operating instructions
If no "CLICK" sound is emitted probably
the PCB has failed. Call the servicing
technicians.
The motor may have over-heated and
the thermal security switch may have
turned on. Wait for about 15 minutes,
allowing the motor to cool down and op-
erate the motor again. If the chair does
not move or the motor over heats imme-
diately after, call the servicing techni-
cians.
Apply the procedure as quoted in para-
graph 4.3.2.
It is impossible to determine the cause of
