OPERATION
BATTERY CHARGER/BATTERIES
The battery pack contains Lithium ion cells. A new battery pack should be charged for
16 hours prior to its first use.
ATTACH THE ADAPTER TO THE POWER SUPPLY
The power supply is a universal-input unit that accepts 100V - 240V AC nominal. Note:
Only Kerr-supplied power supplies (part number 921656) are to be used to power the
Demi
battery charger. There are two types of power supplies available as shown in
Plus
Figure 1 and 3. The power supplies differ slightly in appearance, but operate the same
both electrically and mechanically.
I.
Select the proper adapter (as shown in Figure 2 and 3). Their applications are as
follows:
·
120V US — Type A
·
Euro —Type C
·
UK — Type G
·
Australian — Type I
II.
Each adapter also has a slot into which the retaining latch on the power supply fits.
III. With the slot oriented toward the power supply, place the adapter onto the
power supply so that the tabs on the adapter are aligned with their respective
slots on the power supply.
IV.
Pressing down on both ends of the adapter (Figure 4), slide the adapter into
the power supply until a click is heard and the adapter is locked in place. Note:
Pressing down on the adapter during installation assures that all the tabs are
held by the retainers on the power supply. If the adapter feels loose, remove the
adapter and re-install.
V.
Figure 5 shows the adapter locked in place on the power supply.
VI. To remove the adapter from the power supply, press on the latch retainer button
(7.), slide the adapter away from the power supply, and remove the adapter.
VII. Retain unused adapters for future use.
INSTALL THE BATTERY ONTO THE WAND
I.
The battery will only fit onto the wand in one orientation. If you have difficulty
fitting the battery to the wand, do not force it.
II.
Orient the battery (Figure 6) so that the broad flat area (1.) is toward the side of
the wand that contains the switches.
III. Slide the battery and wand together until a click is heard and the battery is
locked in place.
IV.
To remove the battery (Figure 6), press the textured indents (2.) on both sides of
the battery and slide the battery free.
CHARGE THE BATTERY(IES)
Plug the power supply into the charger base. The socket is located at the back of the
charger base (Figure 7).
I.
Plug the power supply into an electrical outlet.
II.
Insert the battery and/or curing unit with battery into the opening(s) of the
battery charger.
a.
The charger can charge any combination of two batteries or wands (in
differing states of charge) at the same time.
b.
The lighted rings (Figure 7, 2.) that surround the openings in the charger
base indicate the state of charge of each battery as follows:
·
Green light—battery is charged.
·
Yellow light—battery is charging.
·
Blinking Yellow Light (with battery or wand in the charger) —
indicates a fault condition. Please call Customer Service.
Note: If the battery is below room temperature, allow the battery to come up to room
temperature and try again; otherwise, replace the battery.

Battery pack life: 300 full charge/recharge cycles. Output: 3.7-Volts nominal @ 2.1A-H
capacity.
BATTERY DISPOSAL: The battery pack contains a Lithium ion (Li-ion) battery. Recycle or
dispose of batteries according to national, state and local regulations.
RECOMMENDED CURING TIME
The Demi
is a high-output curing unit. Kerr testing indicates the following
Plus
recommended curing times:
Material
Universal composite shades A3 and lighter (2 mm depth)
Universal composite shades A3.5 and darker
Bonding agents, universal resin luting cements and Self-
etch, self-adhesive cements.
Note: It is highly recommended that curing capability be tested using a Hardness Disk
to ensure a complete cure.
HANDPIECE: The Demi
is intended for all-day use without changing the battery. A
Plus
fully charged battery will yield 500, five second cures.
The Demi
is a wand-style curing light used for the polymerization of light-cured
Plus
dental material and is powered by a rechargeable Lithium ion battery pack.
Note: When new, the battery pack must be charged prior to using the Demi
Light. The unit employs proprietary Periodic Level Shifting (PLS), patent pending. PLS
is a constant periodic cycling of the output from a predetermined base level to a higher
level for a short duration of time. The PLS technology provides faster, deeper cures
without overheating.
DEMI
PARTS AND CONTROLS
Plus
The following components are used by the operator during the curing process (Figure 8):
Curing Mode LEDs (1.) Three LEDs represent the three curing modes; from left
I.
to right these are: 5 second, 10 second, and 20 second cycles.
Mode Selection Switch (2.) Pressing this switch sequentially toggles the unit
II.
through the three curing modes. If the unit is in Sleep mode, pressing this switch
awakens the unit in the curing mode last used.
III. Trigger Switch (3.) Pressing (and releasing) this switch initiates the chosen
curing cycle. If the unit is in Sleep mode, pressing this switch awakens the unit in
the curing mode last used.
Battery Power LED (4.) This LED indicates the state of charge of the battery in
IV.
the following way:
If the light is unlit, the battery is either CHARGED or the unit is in Sleep
a)
mode.
b)
If the light is yellow, the battery has a LOW charge.
Note: The curing light will operate normally in this mode. Recharge the
battery at the next available opportunity.
If the light is red, the battery is DISCHARGED (dead-battery) and will
c)
need to be recharged.
So that no curing cycles are interrupted, when the battery voltage drops below
the dead-battery threshold during a curing cycle, the curing cycle will complete
and the battery status LED will not change to red until the curing cycle is
completed.
V.
Lithium-Ion Battery Pack (5.) Use to power the curing wand. Can be removed
by pressing the indents and pulling the battery free.
VI. Light Guide Assembly (6.) The output of the Curing Light LED is emitted from
the end of this piece.*
VII. Light Shield (7.) This shield protects the eyes of the operator from the light
emitted from the Light Guide when in use.
*Other light guides that may yield different outputs are available for the Demi
