Low Batteries
Fading LCD displays and unlit segments of the LCD are indications that the ergoFET battery power may
be low. If LCD segments remain unlit after pressing Reset, the batteries should be changed.
To avoid testing interruptions due to low battery power, we recommend that you check remaining batter
power regularly, and replace batteries when they reach approximately 15% power level. To check battery
power, follow the battery check instructions on page
9.
Changing Batteries
The ergoFET uses (2) 3.7V 1/2AA LI-ION rechargeable batteries, for compact placement, and long life. These
batteries can be purchased from Hoggan Scientific LLC. To change the battery, remove the attachment from the
main unit. Carefully remove the batteries from their holders. When installing new batteries, make sure the
positive (+) posts align with the (+) marks on the ergoFET body. If segments do not light up after installing new
batteries, please contact Hoggan Scientific LLC Customer Service Department at 800-678-7888.
