Using a Power Adaptor
Connect one end of the power adaptor (Yamaha PA-3B) to the DC IN
jack on the rear panel, and the other end to a suitable electrical
outlet.
WARNING
•
Do not attempt to use an AC adaptor other than the PA-3B. The use of
an incompatible adaptor may result in irreparable damage to the MU15,
and even pose a serious shock hazard.
CAUTION
•
When connecting the AC power adaptor, first make sure that the MU15
is turned off (set to STANDBY). Next, connect one end of the power
adaptor to the DC IN jack on the MU15, and connect the other end to
an appropriate AC outlet.
•
The MU15 has a convenient data backup feature that maintains any
changes you’ve made to the settings, even when the power is turned
off. However, removing the batteries or disconnecting the AC adaptor
automatically clears the data and restores the factory defaults. To save
your important data, use the Dump Out function (page 65).
Power Supply
Although the MU15 will run either from an optional AC adaptor or batteries,
Yamaha recommends use of an AC adaptor whenever possible. Moreover, an
AC adaptor is more environmentally friendly than batteries and does not
deplete resources.
CAUTION
•
Before making any connections, make sure that all equipment to be connected is
turned off.
