Replacing the battery

About the battery

Batteries should always be installed or replaced before connecting any other devices. This way, you can prevent malfunction and damage.
If the batteries run extremely low, the sound may distort / interruptions in the sound may occur at high volume levels, but this does not indicate a malfunction. If this occurs, please replace the batteries / use the AC adaptor (sold separately).
If operating this unit on batteries, please use alkaline batteries.
If you handle batteries improperly, you risk explosion and fluid leakage. Make sure that you carefully observe all of the items related to batteries that are listed in “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (leaflet “USING THE UNIT SAFELY” and Owner’s manual)
This device already contains a battery when shipped from the factory. This is a test battery, which may not last as long as a new one.

NOTE

When operating on battery power only, the unit’s indicator will become dim when battery power gets too low. Replace the battery as soon as possible.
If you notice noise when the unit is running on battery power, this may be because the battery is almost depleted. Try replacing the battery or using a separately sold AC adaptor.
If the CHECK indicator keeps switching on and off when the unit is running on battery power, this may be because the battery is almost depleted. Try replacing the battery or using a separately sold AC adaptor.
