Controls
Curing Time Indicator Lights:
Three LEDs represent
the three curing modes; from left to right these are: 5
second, 10 second, and 20 second cycles.
Charge Indicator Light:
This LED indicates the state of
charge of the power source.
Curing Time Selector:
Pressing this button
sequentially toggles the unit through the three curing
modes. If the unit is in sleep mode, pressing this button
awakens the unit in the curing mode last used.
LED Light Button:
Pressing this button initiates the
selected curing cycle. Pressing this button during the
cure cycle will interrupt/end the cycle. If the unit is in
sleep mode, pressing this button awakens the unit in
the curing mode last used.

Operating Modes
NOTE:
For each of the modes explained below, it is assumed that the LED Light Attachment is securely
attached to the Handpiece:
Active
Mode
The “ready” state of the Demi Ultra is Active Mode. In this mode a Curing Time Indicator Light
will be illuminated. The user may cycle between 5 second, 10 second, and 20 second curing
modes by pressing the Curing Time Selector. Curing cycles are also initiated when the unit is
in Active Mode.
Sleep
Mode
The Demi Ultra goes into sleep mode after approximately 60 seconds of no activity, and when
the unit is initially removed from the Charging Dock when charging is complete. While in
sleep mode, all LEDs are turned off and the curing light goes into a lower power state. It can
be awakened by pressing either the Curing Time Selector or LED Light Button once, at which
time the unit will be in Active Mode. The unit will reflect the last cure mode chosen.
Off
Mode
There are two conditions that put the Demi Ultra into Off Mode: (1) When it is seated in the
Charging Dock, and (2) When the unit becomes completely drained. For example, if the unit
is not in the Charging Dock and is left idle for many days the charge will completely drain.
Pressing the control buttons will not awaken the unit if it is in Off Mode. If the charge is
drained, it must be first charged and then removed from the Charging Dock.
Silent
Mode
The Demi Ultra in Active Mode emits sounds to signal activity, such as intermittent beeps
while curing. To mute these sounds, press and hold down the Curing Time Selector Button for
10 seconds. After 10 seconds the unit will beep twice, signaling Silent Mode has been turned
on. The unit will remember this setting, and not produce sounds until Silent Mode is turned
off using the same procedure as was used to switch it on.
Periodic Level Shifting (PLS)
The Demi Ultra employs proprietary Periodic Level Shifting technology. PLS is a constant periodic cycling of
light from a base output to a higher level every second during a curing cycle. PLS technology provides faster,
deeper cures without overheating.
