2. FEATURES
1. Latest LED technology.
2. Minimal heat output.
3. ree preset programs
FAST : Full power output.
PULSE : 0.5 second intermittent output.
RAMP : So Start.
4. Timer
e Led 55N has a xed timer. e unit will cure for a total of 20 seconds. At 10 seconds the light will
beep indicating that you have reached the 10 second time mark. At 20 seconds the light will beep
again and automatically stop the curing process.
5. Built-in light intensity sensor
e led 55N base has the a built in light intensity sensor on the charging base. is will allow the end
user to verify if there is sucient power to cure materials. To verify light intensity you must use a LED
light radiometer.
6. Sleeping Mode
e LED 55N will be in “trickle” charging mode aer 3 min of non - use. Trickle charging mode only
applies if the handpiece is placed on the charging base. If le o of charging base the light will be in sleep
mode.
7. Auto Memory
LED 55N will remain in previous setting, including the curing time and the curing program.
8. Cordless
e LED 55N comes with two re-chargable lithium ion Batteries. once one battery is drained you may
switch to the other battery that will be fullly charged if it has been placed on the charging base.
9. Low Battery / Over Heat indicator
e low battery indicator light will illuminate “red” when the battery
does not have suciant power to operate the light. e over heat light
will illuminate “yellow” if the handpiece has over heated. If the light over
heats allow the light to rest for 10 min. When the light is illuminated “green”
the light has sucient power to cure.

4. Installation
Step 1 : Connect Power Adapter to charging base.
Step 2 : Remove protective battery contact covers.
Step 3: Place the batteries in the charging base. Allow the batteries to fully charge.
For the best performance, charge curing light handpiece continually for 4 hours (charge battery at least 8
hours for rst time using). e battery indicator on the charging base will show the sign of full power when
battery is fully charged. LED 55N will detect the charging automatically. ere will be one short beep tone
generated when it has been properly put on to the Charging Base.
Step 4 : Aer charging is complete attach one battery to the handpiece. Align the threads of the battery to the
back of the handpiece and turn clockwise to fasten. Be sure not to over tighten the battery to the handpiece.
Step 5 : Install light guide into the handpiece. Directly insert it onto the front of the curing light handpiece. e
light guide can be rotated aer installation.
Step 6 : Place the light shield over the light guide. Verify it is secure on the silver chuck of light guide.

4. Installation
Connect power adaptor to
the charging base.
Remove protective battery
covers.
Place batteries in the
charging base.
Attach battery to light
handpiece.
Insert light guide.

3. Light intensity
indicator
Attach light shield.
Charging base indicators
1. light intensity sensor. Place the light guide on
this sensor to verify there is sucient light to cure.
If there is sucient light and battery power the
light sensor will illuminate “purple”. If there is not
sucient light, power or the light guide is damaged
or dirty the light indicator will illuminate “red”.
2. Battery charging indicators. When ahing red
the batteries are charging. When the light is solid
“green” the batteries are fully charged.
3. light sensor indicator. is light is only activted
when the light intensity sensor is being used. A
“purple” light indicates that there is sucient
power to cure. A “red” ligh indicates that there is
not sucient power to cure. Possible reasons for a
“red” light are Low battery, Damaged / dirty light
guide or damaged LED.

6. MAINTENANCE
1. Be sure there is no resin or material sticking to the surface of the light guide.
2. If materials are sticking on the light guide immediately clean it with so cloth. Keep light guide clean for better
light intensity and curing performance.
3. e light guide should be sterilized aer each use. It can be safely autoclaved at 121 °C. For no more then 15
minutes. Let cool before handling.
4. e other accessories such as curing light hadpiece and eye protector should be scrubbed with pure water and
sheathed in accordance with standard disinfection procedures.
5. Keep curing light handpiece in charging station while not in use.
6. Dispose Lithium battery according to the federal and state laws.
7. e User should wear colored protection glasses to avoid eye injury due to LED light.
7. TROUBLESHOOTING
Fault Possible Cause Solution
e low battery indicator on the
curing light is solid red
e overheat indicator light is
orange
When the light is placed on the
charging base the LED emmits a
