About the Power Supply
Battery Operation
The CUBE Street EX can be powered with eight AA batteries (sold
separately). We recommend that you keep batteries installed in the
unit even though you’ll be powering it with the AC adaptor. That way,
you’ll be able to continue a performance even if the cord of the AC
adaptor gets accidently disconnected from the unit.
* 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” (p. 2) and “IMPORTANT NOTES”
(p. 3).
* When operating on battery power only, the unit’s indicator will become
blink when battery power gets too low. Replace the battery as soon as
possible.
Choosing Batteries
This unit can be used with alkaline batteries or rechargeable Ni-MH
batteries. The operating time will depend on the characteristics of
the batteries. Refer to the following table and choose the type of
batteries that you want to use.

Checking the Remaining Battery Amount
When the [BATTERY CHECK/MUTE] switched on, you
can check the amount of power remaining in the
batteries.
* When the [BATTERY CHECK/MUTE] switched on, the
indicator blinks, and sound will not produced from the
CUBE Street EX’s speakers or from LINE OUT jacks and PHONES jack.
* Sounds may distort easily or may cut off when played at high volume as
the battery power begins to fade, but this is normal and does not indicate
a malfunction. In such instances, either replace the batteries or use the AC
adaptor included with the unit.
