8. If you purchase your own battery,
make sure to also apply adhesive
foam pads on the left and right side
of the battery. (You may be able to
peel off the foam strips from the
original battery. If not, you can also
purchase adhesive pads of similar
material and thickness.) These pads
ensure that the replacement battery
is securely fastened and will not
move within the battery cavity.
9. Slide the new battery, with the
terminals at the top, into the cavity
and gently push until the battery is
flush with the back of the EcoTrek.
10. Replace the battery door and
re-insert the screws.
11. Check if the battery door is securely
fastened to the speaker housing. A
loose battery door may compromise
speaker waterproofness.
12. Power on the EcoTrek to ensure
proper function. Be sure to fully
charge the new battery prior to use
(4-8 hours).
