Deep caries provides a
conductive path outside the
canal.
Perforation.
Large lateral canal.
Bad electrical contact.
The connection hook is not
properly connected to the file.
The root canal is obliterated.
In the case of re-treatment: old
filling material residues may
block the root canal.

Solution
Adjust the sound level as
described in the User Manual.
Ensure a good contact between
the mucosa and lip clip (Place
the lip clip in the labial angle
opposite the tooth to be treated).
Clean the connection hook (with
Ethanol).
Block the external conductive
path.
Remove the file, close the
perforation and repeat the apex
detection procedure, carefully
inserting the file into canal.
Try continuing the procedure by
gently advancing the file.
Perform the cable connection
test as described in the User
Manual.
Place the connection hook on
the metal part of the file below
the plastic handle.
Check the comparative X-ray
image for hints.
Remove old root filling material
residues prior to use.
Completely remove the
remnants prior to use.
Rinse the root canal with NaCl
solution. Dry the access cavity
with a cotton pellet/ air-blower.
If there is no parietal contact use
larger ISO size file.
Important: exactly fitting files
lead to precise results.
Contact your distributor.
