Pioneer DVR-RT501-S Operating Instructions Manual page 15

Before using your unit
How to install the batteries
Use dry cell batteries type AAA/R03.
These batteries are offered as carbon / zinc-type. You may use both, but do not mix types.
Note: Flat, weak batteries will leak. Corrosive electrolyte will damage the remote control handset.
Leak proof batteries will not leak immediately when they are flat. As long as the handset is still working, there is
no danger of leakage. To prevent damage, remove the batteries if you do not use the handset for several
months.
Damage because of leakage is not covered by the guarantee.
When disposing of used batteries, please comply
with governmental regulations or
environmental public instruction's rules that
apply in your country/area.
