REMOTE CONTROL
BATTERIES
A standard small flat blade screwdriver is required to install the three
AAA batteries. To install batteries in the remote control, it is necessary to
separate the two sections.
WARNING: When opened, the pushbutton balls will be loose and
care must be taken to properly retain them.
It is recommended to lay the remote control face down on a flat
surface so that the balls will stay in position. Then, remove the three
screws. Lift off the cover and set aside, making certain that the battery
holder comes out from the cover. Install the batteries with the positive
(+) terminals facing as indicated on the holder and replace the cover.
