Troubleshooting
Intensity Auto-Lock:
Once you have started therapy and left the intensity level constant
for 20 seconds, the device will lock to prevent accidental increases to
intensity. You will see a lock symbol appear in the middle of the screen to
indicate that this safety feature is in effect.
To unlock and increase intensity, press the button to decrease the intensity
first, at which point the device will unlock and allow you to turn the
intensity up.
Open Load Detection:
If the intensity of either channel is above 4.5, the Continuum checks to
make sure that there is good contact between the device and the patient.
If bad contact is detected, the text "OPEN" will be displayed instead of the
intensity, and the intensity on both channels will go to zero. The treatment
timer will stop.
To resume treatment, assure that the leadwire is fully connected to the
device and to the electrodes, and that there is good contact between the
electrodes and the skin. Then increase the intensity to the desired level. If
the problem persists, replace the leadwires and electrodes, or contact the
Empi Repair Department for assistance (800.862.2343).
Battery Display:
The battery icon on the top left corner of the display shows the charged
state of the battery. This icon will show full for new alkaline batteries, but
less than full for fully charged rechargeable batteries.
Low battery voltage is indicated by a flashing battery indicator. The device
will display a low voltage message and power down if the battery voltage is
too low. For more information, see "Changing the Batteries" on page 17.
