batteries.
To load batteries
1.
Carefully turn over the Digital Drum, and remove the battery compart-
ment cover.
2.
Load six C-size (LR14) batteries into the battery compartment.
• Make sure that the positive (+) and negative (–) ends of the batteries are
facing correctly.
3.
Insert the tabs of the battery compartment cover into the holes provided

Important Battery Information
The following shows the approximate battery life provided by different
battery types.
• Standard battery life: Approximately 5 hours (LR14)
The above value is 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.
