Acoustical Signals - Handpiece
An acoustical signal is emitted
• every time a button is pressed,
• every time the light is turned ON,
• 1 time after 5 sec exposure time, 2 times after 10 sec,
3 times after 15 sec.
Exception: in continuous mode; an acoustical signal
is emitted every 10 seconds.
Two acoustical signals are emitted
• every time the sleep mode is terminated by pressing
the START button,
• every time the light is turned OFF.
A 2-sec error signal is emitted, if
• the handpiece over-heats,
• the battery lacks sufficient charge.
The acoustical signals from the handpiece can be turned
off (except for the 2-sec error signal). Follow these
instructions to turn them off. Put the handpiece in sleep
mode, e.g., by setting it in the charger. Take the device
from the charger; press first the TIME button, then the
START button. This changes the sleep mode of the
hand piece back to active and the status "Acoustical
signals activated" to "Acoustical signals deactivated".
The acoustical signals can be reactivated by following
the same procedure.
