Be sure to go through this section carefully before using your PSR-730/630. Power Supply Although the PSR-730/630 will run either from an optional AC adaptor or batteries, Yamaha recommends use of the more environmentally safe AC adaptor. Follow the instructions below according to the power source you intend to use. s Using An Optional AC Power Adaptor z Plug an optional Yamaha PA-6 Power Adaptor into a wall AC outlet. x Then plug the DC output cable from the PA-6 into the DC IN 10-12V jack on the rear panel of the PSR-730/630. The internal batteries are automatically disconnected when an AC Power Adaptor is used. DC IN 10-12V PA-6 When turning the power OFF, simply reverse the procedure. s Using Batteries For battery operation the PSR-730/630 requires six 1.5V SUM-1, "D" size, R20 or equivalent batteries. When the batteries need to be replaced "Lo Battery!!" may appear on top of the display, the volume may be reduced, the sound may be distorted, and other problems may occur. When this happens, turn the power off and replace the batteries. Replace the batteries as follows: z Open the battery compartment cover located on the instrument's bottom panel. x Insert the six new batteries, being careful to follow the polarity markings on the inside of the compartment. c Replace the compartment cover, making sure that it locks firmly in place. • Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-730/630 record operation! Doing so can result in a loss of data. • Use ONLY a Yamaha PA-6 AC Power Adaptor (or other adaptor specifically recommended by Yamaha) to power your instrument from the AC mains. The use of other adaptors may result in irreparable damage to both the adaptor and the PSR-730/630. • Unplug the AC Power Adaptor when not using the PSR730/630, or during electrical storms. • When the batteries run down, replace them with a complete 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. • Plugging or unplugging the AC power adaptor while the batteries are installed will reset the PSR730/630 to the defaults. x Important Notes on Battery Use • Since the PSR-730 and PSR-630 consume a considerable amount of power, Yamaha recommends the use of an AC power adaptor rather than batteries. The batteries should be considered an auxiliary power source for data backup. • The floppy disk drive, in particular, uses a large amount of power, so it is important to always use an AC power adaptor when performing disk-intensive operations such as song recording/playback or data load/save. If you attempt to use battery power for these operations and the batteries do fail, you will lose not only the data you're recording or saving, but also other data in internal memory including user styles, user pads, registration memory, etc. • Taking the above precautions into consideration, always use an AC power adaptor when using the PSR-630/730 for an important performance or when creating important data. • When using batteries and the "Lo Battery!!" warning initially appears on the display, the volume will drop a little but you will be able to use the instrument for a while longer. When the "Lo Battery!!" warning begins to appear every few seconds, replace the batteries as soon as possible. 12
