Basic High Volt Setup; Detailed High Volt Setup - Dynatronics Dynatron 850 Plus Service Manual

When setting intensity, the probe must be making contact with the patient's skin. Ensure that
the patient can feel the current as you increase the intensity. Do not increase intensity for
probe treatments if the patient is unable to report feeling the current.

2. Choose the POLARITY (hold down FUNCTION key and press HI VOLT key).
3. Choose the CONTRACTION/REST times (for electrodes treatment only).
4. Choose the RAMP setting.
5. Select (or set up) a PULSE RATE RANGE (High/Low) or set a single pulse rate.
6. Change the treatment TIME, if desired.
7. Raise the INTENSITY to the desired level (for probe treatment, make sure probe is in

8. Press START.
9. Press STOP, if you need to stop a treatment before its time has expired.

Detailed High Volt Setup

1. Press the HI VOLT key.
When you press HI VOLT, the high volt channel and the default settings for high voltage
pulsed stimulation are automatically selected. If you have not already done so, attach
leads and place electrodes on the patient now and plug the lead wire (or probe cable) into
the HV jack. See instructions at the start of this section for setting up electrodes or
probes treatments. If you wish to use the default settings, you can now increase intensity
to the desired level, then press START. If you wish to use other settings, do the
following:
2. Choose the POLARITY.
Polarity is selected by holding down the FUNCTION key and pressing the HI VOLT key
at the same time. Continue pressing FUNCTION-HI VOLT to select either positive ("+")
or negative ("-") polarity or dual polarity (both "+" and "-" LEDs are on). When both are
selected, the device alternates between the two, delivering each polarity for
approximately 30 seconds. NOTE: Some discomfort may be felt by the patient when the
polarities change. If the patient finds this

• Attach lead wire or probe cable to the high volt jack.
• Attach electrodes to patient at this time.
• Give the remote stop cable to the patient.
