distance, in which case, the battery should be replaced
with a new one. If the remote control is going to be idle
for a long time or the battery runs out, please take the
battery out to prevent the remote control from being
corroded by battery leakage which may result in
damage and failure of the remote control.

● Please do not use batteries of different types. It

is not allowed to use old and new batteries together;
the batteries should be replaced in pair.

● Please do not throw the batteries into fire or

charge or decompose the batteries; do not charge,
