Load 6 AA-size batteries into the battery compartment.

Make sure that the positive (+) and negative (–) ends are facing correctly.

Important Battery Information

The following shows the approximate battery life provided by different battery types.

• Standard battery life: Approximately 5 hours (AM3/LR6)

Both of the above values are standard battery life at normal temperature, with the digital drum volume at a medium setting. Temperature extremes or playing at very loud volume settings can shorten battery life.

Any of the following symptoms indicate low battery power. Replace batteries as soon as possible whenever any of the following occurs.

Instrument does not turn on

Dim, difficult to read display

Abnormally low speaker/headphone volume

Distortion of sound output

Occasional interruption of sound when playing at high volume

Sudden power failure when playing at high volume

Dimming of the display when playing at high volume

Abnormal rhythm pattern and demo tune play

Dimming of digital drum lights when notes sound

Caution!

Improper handling of batteries can cause them to burst and leak, which creates the danger of personal injury or damage due to contact with battery acid. Be sure to note the following important precautions.

Always make sure that the positive (+) and negative (–) poles are facing correctly as indicated inside the battery compartment.

To avoid damage caused by leaking batteries, be sure to remove batteries from the digital drum whenever you leave it unattended for long periods (such as when leaving on a trip).

Never mix batteries of different types.

Never mix old batteries with new ones.

Never discard batteries by incinerating them, do not allow their poles to be shorted (connected to each other), never take batteries apart, and do not expose batteries to direct heat.

Replace batteries as soon as possible after any sign they are getting weak.

Never attempt to recharge batteries.
