Issue
Possible Cause
Solution
Increasing intensity
causes unpleasant
sensation.
Dry spots or other
factors that could
increase resistance.
Turn unit “OFF.”
Remove the PC Stim Electrode,
lubricate it generously, reinsert
and then turn unit “ON.”
Use a different brand or style of
lubricant
Local muscle fatigue.
Be less aggressive in mA intensity
or frequency of use.
Never heat, freeze or microwave the PC Stim Electrode.
Use only at euthermia (
e.g.,
normal healthy body temperature),
37.0° ± 0.5°degrees Celsius
Problem:
- Cannot reach maximum mA level; or
- The unit cuts off stimulation at certain level; or
- When increase the intensity, zero mA is flashing; or
- Power is cutting off when using
Solution:
It is normal behaviour in our and any other quality muscle stimulators (and
TENS machines), and in most cases resolves itself - please read the guideance
below.
The stimulation intensity will drop to zero if you simply press the mA+ but-
ton and no electrodes are connected to the channel on which you increase the
intensity. You should attach a pair of electrodes to the lead wire and the lead
should be connected to the channel on which you increase the stimulation
intensity (mA).
