CURRENT LIMIT ERROR MESSAGES
CAUSE
“Cannot start treatment with zero intensity”
Intensity not set
error 101, error 111, error 120, error 130
“lead error: current too low!
Please check or replace your leads and pads!”
lead issue; electrode issue
error 100, error 110, error 140
“lead error: high current delivery detected. adjusting intensity
to a safe limit. Please check leads. space electrodes further
apart. ensure skin is dry between electrodes.”
lead shorted
electrodes touching or too close
hot pack may be too moist
Most warnings will occur during the setup portion of a treatment. It would be rare to encounter a current limit warning during
a patient treatment as reaching the current limit would require an intensity setting that is uncomfortable and intolerable to
most patients. Below are some possible considerations for exceptions:
• The patient is unable to adequately feel the current and is unable; therefore, to report discomfort at the high intensity level.
• When using four large electrodes for a treatment, current is dispersed over a larger electrode surface area permitting
a higher intensity setting without discomfort to the patient.
• For users who need to provide intensity levels above 50mA (not available Japan or Canada), the default may be
changed to 100mA: 1) Begin at the START UP SCREEN. 2) Press the FUNCTION KEY. 3) Use the toggle key under
the MODE WINDOW to select the 100mA option and confirm your choice when prompted. Press STOP to return
to the START UP SCREEN.
As the intensity is increased, ensure that the patient feels the current as expected. If the patient is unable to feel the current,
the current could unintentionally be raised to a level much too high and risk causing unnecessary discomfort or possibly
burn the patient. Keep the intensity very low if the patient has little or no feeling in the treatment area (see “Contraindica-
tions, Warnings, and Precautions” in this manual). If you encounter the Current Limit Warnings, it may indicate that the
patient cannot adequately feel the current. Reduce the intensity immediately.
A wide range of factors can cause the patient to lack sufficient feeling in the treatment area, including, but not limited to, pain
control drugs, use of ice packs, neurological damage, etc.
Always consider these and other factors when delivering an electrotherapy treatment. Determine intensity settings based
upon your medical expertise and judgment.
Error Messages
If an error occurs during any active treatment, whether in or out of focus, the 25 Series will sound a beep. A white box with a red
Error message will appear in the Time area of the Treatment Display Screen, if the treatment is in focus. If the treatment error is
associated with a treatment that is not in focus, “ERR” will appear next to the active treatment listed on the left-hand side of the
screen with other treatments that are currently running but not in focus. Pressing the modality key for the treatment indicated
will bring that treatment into focus and details regarding the error will appear on the Treatment Display Screen.
