Check Points Remedies
Charge the battery.
Install the battery properly.
Replace the battery.
Charge battery if there is no sound.
Broken display if there is a sound.
Select a mode other than EMR mode.
Set beep volume to 1, 2, or 3.
When set to CCW mode, the beeper sounds an alarm
after a set time period elapses. If this is annoying, set
the beeper sound for 0.
Hook the contrary electrode in the corner of the pa-
tient's mouth.
Select a mode other than EMR mode.
Turn the auto start function on.

Tighten the screw securely.
Set the Torque Reverse function for R.L (torque reverse
less) if this is not desired.
Change the Apical Action setting to Off or Stop.
Change rotation mode to something other than CCW
(reverse rotation) mode.
Increase the torque limit value.
The torque limit automatically decreases as the file ap-
proaches the apex. To use a fixed reverse torque value,
turn the Apical Torque Down function off.
In that case, the canal measurement meter could indi-
cate a large movement and reach the flash bar.
Advance the file down the root canal so that the meter
display will resume in the appropriate position and the
file rotation will return to the forward direction.
