Low Battery Charge Display
After frequent use the battery charge of the device may
drop to below 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 com-
pletion of an exposure, and repeated thereafter
whenever any button is touched.
- The 10-sec-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
approx.10 min.
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

Acoustical Signals
An acoustical signal is emitted
• every time a button is pressed,
• every time the light is turned ON or OFF,
• after 10 sec of exposure time have elapsed (1 alarm
signal), 2x after 20 sec, 3x after 30 sec.
Two acoustical signals are emitted
• every time the power-down mode is terminated by
pressing any of the buttons.
A 2 sec-error signal is emitted, if
• the handpiece over-heats,
• the rechargeable battery is discharged to an extent
that reliable polymerization is no longer ensured.
