Solution
In most cases, this screen will appear when
something becomes disconnected (e.g.
lead wires or electrodes). Check the con-
nections between the electrodes and your
skin, the electrodes and the lead wire and
the lead wire and the device. This error
may also appear if the electrodes are too
dry to adhere properly to your skin. In this
case, replace the electrodes with a new
set. When finished, press ( ) to proceed
as directed on the screen. If none of these
corrects the problem, contact Patient Care
or your healthcare provider.
This is most likely caused by the "lock out"
feature that prevents accidental increases
to your intensity. Press the ( ) button to
unlock the keypad, then ( ) to increase the
intensity to the desired level.
This is most likely due to low battery charge.
Plug in the AC Adapter. This can also be
caused by a decrease in sensation over
certain areas of the skin (e.g., those with-
out good nerve conduction, immediately
after ice application, after pain medications
are taken or injected). Use caution when in-
creasing intensity in these situations.
The battery is low. Plug in the AC Adapter.
