4. Battery Change
The main unit has a built-in rechargeable Li-polymer battery.
The built-in battery is removable so you can easily replace it if you have run
out of battery life.
5. Efficient Wireless Microphone
Turn on the power (A) of the main unit and raise the main volume (B) just
before the + mark.
The volume control uses the ▲▼buttons to adjust the volume, and the
volume level is 4 levels.
The adjusted sound state remains the same even when the power is turned
off and on. Press the ▲button 4 times to set the maximum volume (4 levels).
Pressing the ▼button once in step 4 is the standard volume (step 3).
