7.3 Overheat
protection
If multiple curing cycles in rapid succession occur (normally after 18 consecutive cycles,
each lasting 20 seconds), the built-in temperature overload sensor may activate.
Once the overheat protection activates, an acoustical signal (
3 beeps
) is emitted and the
letter “
T
” comes on, steady, at the right top of the display (
Fig. h
).
The activation of the overheat protection temporarily stops the use of the unit for a few minutes.
Allow the hand piece to cool down for at least 4 – 5 minutes, then start the next exposure
by pressing the “
STAND-BY
” button
.
NOTE
The hand piece will automatically exit from the cooling state upon reaching operational temperature
and the letter “
T
” on the display switches off .
7.4
BUILT-IN Temperature overload sensor defective
In case of a defective temperature overload sensor the letter “
T
” comes on (
blinking
) at the
right top of the display (
Fig. k
).
NOTE
If the temperature overload sensor fault occurs during an exposure cycle, the software
allows completing the exposure. No further exposure cycle is allowed by pressing the
“
STAND-BY
” button
and “
4 beeps
” are emitted.
Any further operation with defect temperature overload sensor is prevented.
7.5 Battery-low
signal
When after frequent use the battery charge drops to the minimum level, the Translux 2Wave
microprocessor permits another few cycles in any curing mode, without re-charging the battery.
This condition is signalled at the end of each cycle by “
2 beeps
”.
At the end of a few cycles the remaining battery charge does not allow any further exposure cycle
and this condition is shown on the display by the battery icon without internal black bars (
Fig. m
).
Charge the battery!

Cleaning, disinfection and sterilisation
DISCONNECT FROM MAINS
Before carrying out the cleaning and disinfection procedures disconnect the charging base from the electrical
power source!
WARNING
Control of infections
The light guide and the protective light cone are delivered in
NON
STERILE
condition and must be cleaned,
disinfected and sterilised (steam) before being used for the fi rst time as well as before every use.
Do not
sterilise the hand piece and the charging unit!
Do not
sterilise the battery!
8.1 Disassembly
Remove the protective light cone from the light guide.
Remove the light guide: Rotate the light guide slightly and pull it out from the hand piece.
8.2
LIGHT GUIDE – Cleaning and disinfection
CAUTION
Do not
use sharp or pointed instruments to clean the light guide, since they could scratch the surface of the
light guide and thus decrease light transmission.
Do not
use cleaning / disinfectant agents containing organic, mineral and oxidising acids, hydrogen peroxide,
chloride, iodine, bromide and solvents.
