CARE AND MAINTENANCE
14. Front Cover. A removable panel covers the controls for pulse
frequency, pulse width, mode switch and battery compartment.
Your medical professional may wish to set these controls for you
and request that you leave the cover in place.
15. Battery. Dimming of the Indicator lights signifies that the battery
should be replaced with a new one as soon as possible.
However, the stimulator will continue to operate for several more
hours. To replace battery, remove front cover (see above), and
extract battery, replace with a 9 volt alkaline or similar
rechargeable battery, taking care that the battery is inserted
correctly. (See diagram inside battery compartment.) This
TENS unit is designed to be used with batteries only, and cannot
be operated from a line-powered battery charger.
