Low Battery Charge Display
After frequent use the battery charge of the device may
drop to below approximately 10%, so that only a few
more exposures can be performed without re-charging.
Low battery charge is shown by several means:
- A short audible alarm is emitted 5x at the
completion of an exposure, and repeated
thereafter whenever any button is touched.
- The 5-second-LED of the handpiece begins to
flash.
The handpiece should be placed in the charger as
soon as possible to re-charge the battery.
Power-Down Mode
Once the handpiece is placed in the charger, all internal
functions and LEDs are automatically turned off as the
handpiece switches to power-down mode. This reduces
the power consumption of the rechargeable battery to
a minimal level. Outside the charger, the handpiece is
also switched to power-down mode if left unused for
approximately 10 minutes.
To terminate the power-down mode press one of
the two buttons.
- The power-down termination signal (two short
audible signals) is emitted indicating that the

and time settings.
Acoustical Signals - Handpiece
An acoustical signal is emitted
• every time a button is pressed,
• every time the light is turned ON or OFF,
• after 5 seconds of exposure time have elapsed
(1 alarm signal), 2x after 10 seconds, 3x after
15 seconds.
Two acoustical signals are emitted
• every time the power-down mode is terminated by
pressing any of the buttons.
A 2-second-error signal is emitted, if
• the temperature control is activated,
• the rechargeable battery is discharged to an extent
that reliable polymerization is no longer ensured.
Acoustical Signals - Charger
Ongoing beeps are emitted when the handpiece is in
the charger and the charge contacts are wet.
