automatically, and will rotate forward when the torque is disappeared.
Release the foot switch, the file stops.
Notice: when the instrument is in M4-M9, please don't use
the adaptor for it cannot get an exact value.
M4：In this mode, only apex locator functions, methods of operation are as follows:
NOTICE: it cannot get an exact value of the apex length when the
treatment is in an unstable condition. So, please insert
the file into the root-canal and take an X-ray photo to
make sure the veracity.
1. The plug of the testing wire should be completely plugged into
hole on the main unit.
* When you need to pull out the test wire, please don't pull the wire but
hold its pin and pull it out.
2. Clip the metal part of the file with the holder and hang the stainless
electrode up at any side of the patient's mouth.
3.Insert the file into the root-canal，and circumrotate the file toward the
apex of the root-canal. And then the distance between the tip of the file
and the apex of the root-canal will be displayed on the LCD screen. When
the figure on the LCD screen shows 0.5mm, please fasten the file with
the rubber vernier caliper on the reference point of the tooth crest rather
than keep up probing into the root-canal. Then measure the distance
from the bottom of rubber vernier caliper to the tip of the file.
* Root-canal length is the file distance when the LCD displays 0.5.
4. Deciding the working length of root canal
When the figure on the LCD screen shows 0.5mm, then measure the
distance from the bottom of rubber vernier caliper to the tip of the
file. Take note of this figure. So subtract 0.5-1.0mm from the above
data is the working length of root-canal.
When the file drills through the root-canal, please make the final value in
terms of the one measured in 0.5mm.
The working length of root-canal varies from each other for the reason of
different shapes of teeth and root-canal.
5. When the file reaches the position to 2.0mm away from the apex of the
root-canal, there will be a continuous alarm.

rotates forward, the file stops working when it reaches the setting
apex position.
M6: Apex locator & auto reverse1 motor function, press foot
switch the file rotates forward and reverses when it reaches the
setting apex position and stops without touching the root canal.
M7: Apex locator &autoreverse1 motor & slowdown function, press
foot switch the file rotates forward and automatically slows down
when approaching to apex and reverses automatically when it
reaches the setting apex position and stops without touching the
root canal.
M8: Apex locator & auto reverse1 motor& automatically start and
stop function (no need foot switch in the mode). The file starts to
rotate forward when it entering into the root canal and reverse
when it reaches the setting apex position, and stops without
touching the root canal.
M9: Apex locator & auto reverse1 motor & automatically start and
stop & slowdown (no need foot switch in the mode). The file
starts to rotate forward when it entering into the root canal and
automatically slows down when approaching to apex and reverses
automatically when it reaches the setting apex position and stops
without touching the root canal.
Reverse: Press the REVERSE button, file will reverse and you can
change the forward and reverse by press the REVERSE button.
Notice：When the torque reaches or exceeds the setting torque in
M5-M9, and no matter the root canal enlarged file
reaches the set data or not, the file would stop or
reserves automatically.

1. Battery power
LCD displays the current battery power, the number of lattice shows more, and the
power is fuller. If there is no electricity the lattice will flicker，which means the
battery power is about to run out , at this status the beeper will ring per 3S, and
unit will shut down after 60S.
2. Battery recharging
