 Preparing the Power Supply (How to Replace Batteries) The SILENT BassTM uses batteries for its power source. Before installing or removing the batteries, remove the cable from the output jack. 1. On the backside of the instrument, push down the battery case's latch in the direction of the "OPEN" arrow to remove the battery case. NOTICE • When removing the battery case, tilt the instru- ment body at an angle to prevent the battery case from flying out. 2. Insert the batteries into the case. Referring to the illustration, make sure the batteries are placed in the case with the polarity (+/-) properly aligned. 3. Push in the battery case all the way until you hear a click. Battery case AA batteries (alkaline or nickel hydride) Latch  When to Replace the Batteries • When the batteries are running low, the status display LED flashes in red. Promptly replace the batteries. • With nickel hydride batteries, the discharge properties may cause the power to turn off before the LED flashes in red. Be careful of the following when replacing the batteries. • Battery shapes (battery terminals and external shapes, etc.) vary depending on the battery manufacturer. Inserting a battery with a shape different from the battery case may damage the instrument or the like. Even if the batteries fit in, poor contact with the terminals can cause a fire. • Always follow the polarity signs (+/-) when inserting batteries. Improper insertion can cause a fire. • If not using the instrument for a long period of time, remove the batteries from the instrument. Failure to do so can cause battery drainage or damage to the instrument due to battery leakage. SLB300 PRO SLB300 Owner's Manual 16
