Setting Up
Be sure to do the following operations BEFORE turning on the power.Power Requirements
Although the instrument will run either from an optional AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible. An AC adaptor is more environmentally friendly than batteries and does not deplete resources.
q Make sure that the power of the instrument is off (the backlit display is off).
WARNING
•Use the specified adaptor
w Connect the AC power adaptor to the power supply jack.
e Plug the AC adaptor into an AC outlet.
CAUTION
•Unplug the AC Power Adaptor when not using the instrument, or during electrical storms.

q Open the battery compartment cover located on the instrument’s bottom panel.
w Insert the six new alkaline batteries, being careful to follow the polarity markings on the side of the compartment.
e Replace the compartment cover, making sure that it locks firmly in place.
CAUTION
•Never connect or disconnect the AC power adaptor when the batteries are installed in the instrument and the power is on. Doing so will turn the power off, possibly resulting in loss of the data being transferred and the data cur- rently in the transfer destination during transferring or recording a data.

For battery operation the instrument requires six 1.5V “AA” size, LR6 or equivalent batteries. (Alka- line batteries are recommended.) When battery power becomes too low for proper operation, the volume may be reduced, the sound may be dis- torted, and other problems may occur. When this happens, make sure to replace all batteries, following the precautions listed below.
If necessary, also make sure to save all important User data (see page 31), since custom panel settings are lost when the batteries are removed.
CAUTION
•Use alkaline batteries for this instrument. Other types of batteries (including rechargeable batteries) may have sudden drops of power when battery power becomes low, possibly resulting in loss of data in the flash memory.
•Make sure to install the batteries with the proper orienta- tion, maintaining the correct polarity (as shown). Incor- rect battery installation may result in heat, fire and/or leaking of corrosive chemicals.
•When the batteries run down, replace them with a com- plete set of six new batteries. NEVER mix old and new batteries. Do not use different kinds of batteries (e.g. alkaline and manganese) at the same time.
•If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid leakage from the battery.
•Please use the power adaptor when transferring data to flash memory. Batteries (including rechargeable types) can be drained rapidly by this type of operation. If the bat- teries do become drained during a data transfer, both the data being transferred and the data currently in the trans- fer destination will be lost.
