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 - 0V AC nominal. Note:
Only Kerr-supplied power supplies (part number 91656) are to be used to power the
Demi battery charger. (Fig.1)
I.
Select the proper adapter. Their applications are as follows (Fig.2):
• 10V US — Type A (1.)
• Euro —Type C (.)
• UK — Type G (.)
• Australian — Type I (.)
II.
Each adapter contains -tabs (5.) that slide into retainers on the power supply.
Each adapter also has a slot (6.) into which the retaining latch on the power
supply fits. (Fig. 3)
III. With the slot (6.) 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. (Fig. 3)
IV. Pressing down on both ends of the adapter, 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 (as
discussed below) and re-install. (Fig. 4)
V. Fig. 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. (Fig. 5)
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, don't force it.
II. Orient the battery so that the broad flat area [Fig. 6 (1.)] is towards 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, press the textured indents [Fig. 6 (.)] on both sides of
the battery and slide the battery free.
CHARGE THE BATTERY(IES)
I. Plug the power supply into the charger base. The socket is located at the back of
the charger base. [Fig. 7 (1.)]
II. Plug the power supply into an electrical outlet.
III. Insert the battery and/or curing unit with battery into the opening(s) of the
battery charger as shown.
a. The charger can charge any combination of two different batteries or
wands (in differing states of charge) at the same time.
b. The lighted rings [Fig. 7 (.)] 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.
Qty. Description
1 8-mm curved turbo light guide
1 Plug-in power supply
1 Battery pack
1 Demi disposable barrier
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: 00 full charge/recharge cycles. Output: .7-Volts nominal @
.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
recommended curing times:
Material
Universal composite shades A3 and lighter (2-mm depth) ...............................5 seconds
Universal composite shades A3.5 and darker .................................................10 seconds
Bonding agents, universal resin luting cements
and Self-etch, self-adhesive cements, Maxcem™ .............................................5 seconds
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
fully charged battery will yield 500, five-second cures..
The Demi is a wand-style curing light used for the polymerization of light-cured 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 Curing
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
The following components are used by the operator during the curing process (Fig. 8):
I. Curing Mode LEDs (1.) There are three LEDs representing the three curing
modes; from left-to-right these are: 5-second, 10-second and 0-second cycles.
II. Mode Selection Switch (2.) Pressing this switch will sequentially toggle the
unit through the three curing modes. If the unit is in "Sleep" mode, pressing this
switch will "awaken" the unit in the curing mode last used.
III. Trigger Switch (3.) Pressing (and releasing) this switch will initiate the chosen
curing cycle. If the unit is in "Sleep" mode, pressing this switch will "awaken" the
unit in the curing mode last used.
IV. Battery Power LED (4.) This LED indicates the state of charge of the battery in
the following way:
a) If the light is unlit, the battery is either CHARGED or the unit is in "Sleep"
mode.
If the light is yellow, the battery has a LOW charge. Note: The curing
b)
light will operate normally in this mode. Recharge the battery at the next
available opportunity.
c) If the light is red, the battery is DISCHARGED (dead-battery) and will
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.) Used 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.
