SETTING UP
An optional set of stereo headphones can be connected
to the Phone/Output jack located on the rear panel.
When headphones are plugged into the jack, the internal
speakers will switch off automatically, perfect for private
practice or late night playing. If you want to use an
external sound system, the Headphone Jack can also
be used to connect the digital drum to a stereo system
or mixing console.
* Turn all equipment off before making any connections.
Using headphones
Your SDMK4 will run on batteries or from the included power adapter.
Using an AC Adapter
Connect the power adapter to the DC IN jack located
on the rear panel of the unit, and plug the AC power
adapter into an AC power outlet. Do not use adapters
other than the one specified. The technical specification
of the adapter is 9V DC output, 800mA, center
positive type.
Using Batteries
1 Open the battery compartment cover on
the underside of the unit.
2 Insert six “C” size batteries. When inserting
the batteries, be careful to follow the
polarity markings.
3 Close the battery compartment.
Power supply
NOTES Power will be automatically drawn from the AC adapter if an optional AC adapter is connected while batteries are installed in the instrument.
CAUTION: It is recommended that you replace worn batteries as soon as possible. When battery voltage drops, the display will dim and/or the sound will become
distorted. When this occurs, replace the batteries with a complete set of six new batteries of the same type.
NEVER mix old and new batteries, different types of batteries (alkaline, magnesium, etc.), batteries by different makers, or batteries from the same maker but of different types. Misuse
may cause the instrument to become hot, resulting in fire, or battery leakage. Also, to prevent damage due to battery leakage, remove all the batteries from the instrument when it is not
to be used for an extended period of time. Batteries left in an unused instrument will also loose their power over time.
