Battery life
About half a year of normal operation can
be expected when using the Sony SUM-3
(NS) batteries.
When the battéties are exhausted, the
commander cannot operate the stereo
system. When this happens, replace both
batteries with new ones.
To avoid battery leakage
if the commander is not to be used for a
long time, remove the batteries to avoid
damage caused by battery leakage and
corrosion.
