patient.
3. Connect the probe cord.
Connect the file holder to gray connector and the contrary electrode to
white one.
1. Turn power on.
2. Select memory “m2”.
Press the Main switch and make
sure the motor runs smoothly.
* Any memory except EMR mode may
be used.
3. Touch the contrary electrode
with the clip on the end of the
file holder and check that all the
indicator bars on the meter in
the LCD display light up.
4. Touch the contrary electrode
with the file and check in same
way.
⹅After Use
Always turn the instrument off.
1. Remove the file.
2. Take off the HP protective
sleeve.
3. Charge the battery.

⹅Calibration
Calibrate the instrument at the following
times:
• Right after purchase.
• Whenever the contra angle has been
replaced.
• Whenever, in OTR mode, the instrument
always alternates between forward and
reverse rotation and never rotates forward
continuously.
“Calibration” in the Operation Instructions.
1. Wash with running water and dry.
2. Use a threeway syringe etc. to blow
dry all moisture.
3. Wipe the components with a piece
of gauze that has been dampened
with Ethanol for Disinfection (Ethanol 70 to 80 vol%) and wrung out
thoroughly.
4. Lubricate only the contra angle with
the LS spray (LS oil).
5. Put components in individual autoclave pouches.
6. Autoclave the components.
* 134°(273.2° F) for at least 6 minutes or
121°(249.8° F) for at least 60 minutes.
1. Wipe the components with a
piece of gauze that has been
dampened with Ethanol for Disinfection (Ethanol 70 to 80 vol%)
and wrung out thoroughly.
