6. REPLACEMENT OF BATTERIES

A battery symbol is shown on the display when the batteries are almost empty . As long as the
48
stimulator is working normally you can continue the treatment. When stimulation feels weaker than
usual or the stimulator turns off, it is time to replace the batteries.
If the stimulator is not used for some time (approximately 3 months), the batteries should be removed
from the stimulator.
The stimulator operates on either two non-rechargeable 1.5 V AA batteries or two rechargeable 1.2 V AA
batteries, recharged in a separate charger.
The endurance of the batteries depends on the amplitude and number of channels activated during a
program being used. For example, if you use one channel at P1 with an amplitude of 30 mA the non-
rechargeable batteries last approximately 11 hours and rechargeable 7 hours.
