     Unit is not turning on.

     A: This is the most common complaint that we receive from the customers.

     Almost 98% cases are due to lack of charging.

      Why does my Friendo Heating Condensation Pen stop heating after a few seconds?

     A: The heating stops after 3 seconds and activates again after a short pause because we have upgraded our software to prevent any burns with longer heating cycle during the treatment for patient safety.


Endo-Apex (Gutta-Easy)

     My Gutta Easy obturation gun shows “Er1”.  What does this mean?

     A: “Er1” shows on LED display when the heater is in a bad contact with the PCB inside. Try turning the heater around and if it still doesn’t work, please request for an inspection.


     My Gutta Easy obturation gun does not turn on. What should I do?

     A: If the gun was not charged, charge it, and try turning it on again.

     Also, try the reset button on the bottom of the handpiece. Press the square button. Once pressed, it will click in. Leave it for few seconds and press it again. Unit will turn on. If it still doesn’t turn on, please request for an inspection.


     Gutta percha pellet is stuck in my Gutta Easy obturation gun and does not work.

     A: Please request for an inspection. Our repair department would have to disassemble the unit and remove the pellet inside.

     To prevent this from happening, please use 1 pellet at a time. Do not use 2. Once the pellet is inserted, insert the plunger pushing towards the mouth of the handpiece.

     Also, make sure the plunger has the white o-ring (Teflon ring) in place.



     C-Warmer displays “OHE”

      A: “OHE” appears when the temperature is set lower than the current set temperature.


      C-Warmer LED display is flickering

      A: LED display may flicker due to inconsistent flow of electricity via adapters. Check your adapter connection on the back of the unit and the power outlets on the wall.


     Charger has a burning smell.

      A: When different adapter is used, since the voltages are different, it will burn your unit. It is very crucial that you use our adapters for our products only. Please contact us immediately


      Battery pins / Charger pins are corroded and will not charge.

     A: Pins corrode due to too much sterilization. Any liquid left from sterilization will cause corrosion.

     Make sure to have the unit dry after sterilization.
