Your CBX-K1 will run either from an optional power
adaptor or batteries. Follow the instructions below accord-
ing to the power source you intend to use.
Before making any connections, make sure that
all equipment to be connected is turned off.
Using a Power Adaptor
Connect one end of the power adaptor (the optional)
Yamaha PA-1B or PA-3) to the DC IN jack on the rear
panel, and the other end to a suitable electrical outlet.
Do not attempt to use a power adaptor other than
the PA-1B or PA-3. The use of an incompatible adaptor
may result in irreparable damage to the CBX-K1, and
even pose a serious shock hazard.
Be sure to disconnect the power adaptor from the
outlet when the CBX-K1 is not in use.
To use the CBX-K1 on battery power, remove the battery
compartment cover (as shown below) and insert six 1.5V
AA size (SUM-3, R-6 or equivalent) manganese or alkaline
batteries in the battery compartment. Make sure to follow
the polarity indications on the bottom case.
Securely replace the battery compartment cover when done
installing the batteries.
When to Replace the Batteries
When the battery power runs too low to properly operate
the CBX-K1, the V lamp will flash slowly. When
this happens, replace all batteries with a complete set of six
new batteries of the same type.
NEVER mix old and new batteries or
different types of batteries! Also, to prevent possible
damage due to battery leakage, remove the batteries
from the instrument if it is not to be used for an ex-
tended period of time.
Turning the power off and on again
resets all settings to the factory default, cancelling all
