Safety information2
- Illumination devices such as fluorescent lights and the Film viewer which use an
inverter can cause the device to operate erratically.
Do not use the device near devices such as these.
- Electromagnetic wave interference could cause this device to operate in an abnormal,
random and possibly dangerous manner.
Cellular phone, transceivers, remote controls and all other devices which transmit
electromagnetic waves located inside the building should be turned off.
- Do not let the file touch the gums. This will cause the meter to jump toApex.
- If the canal is extremely dry, the meter may not move until it is quite close to the apex.
If the meter does not move, try moistening the canal with oxydol or saline.
- Occasionally the meter will make a sudden and large movement as soon as the file is
inserted into the root canal, but it will return to normal as the file is advanced down
towards the apex.
- The lip hook could cause an adverse reaction if the patient has an allergy to metals.
Ask the patient about this before using the lip hook.
- Take care that medicinal solutions such as formalin cresol or sodium hypochlorite
do not get on the file hook or the lip hook. These could cause an adverse reaction
such as inflammation.
- Always clip the file hook to the upper part of file shaft, near the handle.
The metal and plastic part of the file hook can be damaged if they are attached to the
file’s cutting part or the transition to the cutting part.
- Use files and reamers with plastic handles only.
If the file has a metal handle, electrical leakage will occur when the handle is touched by
fingers and it will prevent an accurate root canal measurement. Even if the file handle is
made of plastic, make sure not to touch the metal part of the file with finger.
