Usage and liability
– Bluephase N must only be employed for the intended
use. Any other uses are contraindicated. Liability can-
not be accepted for damage resulting from misuse or
failure to observe the Operating Instructions.
– The user is responsible for testing Bluephase N for its
use and suitability for the intended purposes. This is
particularly important if other equipment is used in the
immediate vicinity of Bluephase N at the same time.
– Use only original spare parts and accessories from
Ivoclar Vivadent (see Accessories). The manufacturer
does not accept any liability for damage resulting from
the use of other spare parts or accessories.
– The light probe is an applied part and may warm up to
a maximum of 45 °C (113 °F) at the interface to the
handpiece during operation.
Operating voltage
Before switching on, make sure that
a) the voltage indicated on the rating plate complies with
the local power supply.
b) the unit has acquired the ambient temperature.
If the battery or power pack are used separately, e.g.
during start-up or Click & Cure corded operation, contact
with patients or third parties must be prevented. Do not
touch the exposed contacts of the battery or connection
plug (power pack).
Assumption of impaired safety
If it has to be assumed that safe operation is no longer
possible, the power must be disconnected and the bat-
tery removed to avoid accidental operation. This may be
the case, for example, if the apparatus is visibly dam-
aged or no longer works correctly. A complete disconnec-
tion from the power supply is only ensured when the
power cord is disconnected from the power source.
Eye protection
Direct or indirect exposure of the eyes must be prevent-
ed. Prolonged exposure to the light is unpleasant for the
eyes and may result in injury. Therefore, using the sup-
plied anti-glare cones is recommended. Individuals who
are generally sensitive to light, who take photosensitiz-
ing drugs, have undergone eye surgery, or people who
work with the apparatus or in its vicinity for long periods
of time should not be exposed to the light of this device
and wear protective goggles (orange) that absorb light
below 515 nm.
Battery
Caution: Use only original spare parts, particularly Ivoclar
Vivadent batteries and charging bases.
Do not short circuit battery. Do not store at temperatures
above 40 °C / 104 °F (or 60 °C / 140 °F for a short
period). Always store batteries charged. The storage
period must not exceed 6 months. May explode if
disposed of in fire.
Please note that the lithium polymer battery may react
with explosion, fire, and smoke development in case of
inappropriate handling and mechanical damage.
Damaged lithium polymer batteries must no longer be
used.
The electrolytes and electrolyte fumes released during
exlosion, fire, and smoke development are toxic and
corrosive. In case of contact with the eyes and skin,
immediately rinse with copious amounts of water. Avoid
the inhalation of the fumes. See a physician immediately
in case of indisposition.
Heat development
As it is the case with all high-performance lights, the
high light intensity results in a certain heat development.
Prolonged exposure of areas near the pulp and soft
tissues may result in irreversible or reversible damage.
Therefore, the recommended curing times have to be
observed. Uninterrupted curing times of more than
20 seconds on the same tooth surface, as well as direct
contact with the gingiva, oral mucous membrane, or
skin, have to be prevented. If required, polymerize
indirect restorations at intermitting intervals of
20 seconds each or use external cooling with an air
stream.
