Battery Level Indicators; Sleep State - DENTSPLY SmartLite iQ Guía De Operaciónes

NOTE: When curing non-DENTSPLY VLC materials, always refer
to the manufacturer's directions for curing times.
DENTSPLY makes no recommendations for curing times of
non-DENTSPLY VLC restorative materials and curing times
for those materials are at the sole discretion of the clinician.
NOTE: As with any curing instrument, curing times should be
extended when curing through tooth structure or when the
distance from the curing light probe to the material
exceeds 3mm.
Handpiece Liquid Crystal Display (LCD)
The LCD display provides information about the curing mode,
exposure times and battery status of the SmartLite iQ2 unit.
• When the unit is off the charging base and in the ready state the
LCD shows the mode and battery charge level. (Figure 5)
Curing State
Figure 5
• During a curing cycle, the LCD shows the battery level and
either a countdown or count up timer depending upon the
selected curing mode (see Selecting a Curing Mode).
When the handpiece is on the base and the charging base is
properly connected to an AC power source the LCD shows only
the battery level indicator. If the battery is recharging, the black
bar in the battery icon will cycle from low to high (Figure 6).

• In the Sleep State the LCD becomes blank.
• In an Error State the LCD will display an error code
(see Figure 9).
Selecting a Curing Mode
The unit has several different curing time modes. Any one of the
various modes may be selected simply by pressing the UP or
DOWN buttons on the top of the handpiece next to the LCD
window (see Figure 5). Pressing and holding either one of these
buttons will automatically scroll through the modes. Each button
activation is accompanied by a single audible tone.
1. Standard Modes: The SmartLite iQ2 unit has five pre-set curing
cycles (10, 15, 20, 30, and 40 seconds) The cycle time is
displayed on the LCD and upon activation a countdown timer
begins.
2. Continuous Mode: The SmartLite iQ2 unit has a 60-second
"continuous" mode. The continuous mode is displayed as "000"
on the LCD and upon activation a count up timer begins and an
audible tone sounds every 10 seconds.
Activating and Stopping a Curing Cycle
1. The fiberoptic probe can rotate 360 degrees within the hand-
piece. Rotate the probe in its socket until the tip of the probe is
positioned as desired.
NOTE: When using the 12mm-8mm probe (provided with
unit) the DENTSPLY VLC Material Curing Guide
may be used to determine minimum curing times.
The output power of the unit should be measured/tested before
use with the radiometer built into the charging base. See
Radiometer Operation below.
2. Starting the Curing Cycle: Pressing the raised button in the
trigger position of the handpiece (Figure 7) activates the
SmartLite iQ2 unit. At the start of any curing cycle a single
audible tone will sound; at the end of the cycle the curing LED
will turn off automatically and a double audible tone will sound.

3. Cycle Interrupt: If the handpiece is triggered during a curing
cycle, the curing LED will shut off and the unit will sound a
double audible tone.
NOTE: During a curing cycle the Mode Selector switches are
disabled and will have no effect on the unit.
If the handpiece enters an error state at any time a triple
audible tone will sound and the curing LED will shut off.
Triggering the unit while it is in an error state will result in a
triple audible tone. See Errors for information.
Radiometer Operation
In order to provide performance characterization of the curing unit,
including the curing probe, the SmartLite iQ2 unit charging base
has been designed with an on-board radiometer. It is recommended
to test the light on the radiometer before each procedure to
ensure optimal curing performance of the entire light system.
1. Remove the handpiece from the charging base and place the
output end of the fiberoptic probe onto the radiometer detector
(Figure 8).

2. Activate the curing cycle (see Operation above). The radiometer
will light one of three radiometer indicator lights on the charging
base immediately above the radiometer detector corresponding
to three power levels (see Figure 8):
Green: Unit is providing full curing power and will cure in
accordance with the minimum curing times on the DENTSPLY
VLC Materials Curing Guide (provided) and as recommended in
this operations guide.
Amber: Output is compromised. Check fiberoptic probe for
complete seating, damage, and/or foreign matter on the probe
that may interfere with light emission (see Curing Probe Care).
In this output range, it is recommended that the curing time be
doubled. Upon completion of procedure, please contact
DENTSPLY Caulk at number below.
Red: Do not use the unit. Check fiberoptic probe for complete
seating, damage, or foreign matter on the probe that may
interfere with light emission (see Curing Probe Care).
NOTE: If amber or red conditions persist, contact DENTSPLY
Caulk Professional Services at 1-800-532-2855 ext. 249.
Customers outside the USA should contact their nearest
DENTSPLY location, as listed in back of this manual.
If none of the radiometer LED's illuminate ensure that there is
power to the base charger by checking that the power indicator
light is on (see Figure 3). Next verify that there is light emitting
from the curing probe (do not look directly at the output end of the
curing probe). If there is no light check that the unit is not in an
Error State. For information on Error States, see Errors section.
NOTE: If any of these conditions persist, contact DENTSPLY
Caulk Professional Services at 1-800-532-2855 ext. 249.
Customers outside the USA should contact their nearest
DENTSPLY location, as listed in back of this manual.
NOTE: The radiometer on the SmartLite iQ2 unit charging base
has been designed for use with the SmartLite iQ2 unit
handpiece only. Use of any other curing light source may
damage the radiometer detector or provide misleading
information to the user and is not recommended.
NOTE: Curing Probes: The radiometer on the SmartLite iQ2 unit
charging base has been designed for use with the
12-8mm curing probe supplied with the unit only. Using
with other probes may lead to misleading readings and are
not recommended for use with the radiometer.

BATTERY LEVEL INDICATORS

LCD Display
The LCD displays information about the battery status in a battery
shaped icon. Black bars in the icon indicate the battery level
(see Figure 6). Bars are a relative indicator of battery strength.
3 and 4 Bars: No recharge required
2 Bars: Recharge recommended after completion of procedure
0 and 1 Bar: Recharge required prior to use
Battery Indicator Light
The battery indicator light (see Figure 4) on the top of the
handpiece above the LCD window provides information about the
battery level and charging status of the handpiece. The information
from this light also depends upon whether the handpiece is on or
off the charging base as described below:
• When the handpiece is removed from the charging base, the
battery indicator light indicates charge level showing a green,
amber, or red light corresponding to the level of charge of the
battery:
Green: No recharge required
Amber: Recharge recommended after completion of procedure
Red: Recharge required prior to use
NOTE: The SmartLite iQ2 unit has been designed to provide full
output power regardless of the charge status of the battery.
In the event that there is insufficient battery power to drive
the SmartLite iQ2 unit, the unit will automatically shut
down, three audible tones will sound, and the LCD will
display error code E1. See Errors.
• When the handpiece is placed onto the charging base, the
battery indicator light will be green, regardless of the state of the
battery.
• In the sleep state the battery indicator light turns off.
RECHARGING
The SmartLite iQ2 unit has been designed to provide sufficient
battery power for multiple days of use in a busy dental operatory
with a fully charged battery. For best results return the handpiece
to the charging base at the end of each day, or preferably after
each procedure.
1. Place the handpiece into the charging base. Be sure that the
bottom of the handpiece is properly seated so that the charging
pins of the charging base come into contact with the charging
pads of the handpiece (see Figure 4).
2. When the handpiece is properly seated in a powered charging
base, the battery indicator light on the handpiece will be green:
Blinking indicator light: Charging
Solid indicator light: Fully Charged
3. When the handpiece is properly seated in a powered charging
base, the LCD battery icon will display one of the following:
(see Figure 6).
Cycling Battery Icon: Charging
Solid Battery Icon: Fully Charged
4. When the handpiece is on the charging base, the curing time of
the LCD display is disabled. Simply remove the handpiece from
the charging base to restore these displays.

SLEEP STATE

The handpiece of the SmartLite iQ2 unit will enter a "Sleep" state
to minimize battery drain whenever it has been removed from its
charging base for more than 10 minutes without activation. It will
also enter this state 10 minutes after loss of power to the charging
base when the handpiece is on the charging base.
1. In Sleep State the LCD and battery indicator light on the top of
the handpiece will turn off.
2. To wake the unit from Sleep State and return it to Ready State,
it is necessary only to press any button on the handpiece.
3. Placing the handpiece on a properly powered charging base will
also wake the unit.
NOTE: The last used curing mode will be retained while the unit is
in its sleep state.
NOTE: The unit will not enter "sleep" state while in a properly
powered charging base.
ERRORS
The SmartLite iQ2 unit has been designed to operate with
consistent output power and for long life. In order to ensure the
proper operation of this light under normal use, several self-
diagnostic tests have been incorporated into the unit. These
diagnostic tests and the resulting error codes are described
