Setting Up Power Requirements Although the instrument will run either from an 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. Using an AC adaptor 1 Make sure that the power of the instrument is off (the backlight display is off). WARNING • Use the specified adaptor (page 42) only. Using the wrong adaptor can result in damage to the instrument or overheating. • See "For the AC adaptor with a Removable Plug" (page 46). 2 Connect the AC adaptor to the DC IN jack (power supply jack). 3 Plug the AC adaptor into an AC outlet. CAUTION • When setting up the product, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Installing the batteries 1 Make sure that the power of the instrument is off. 2 Open the battery compartment cover located on the instrument's bottom panel. 3 Insert the six new batteries, being careful to follow the polarity markings on the inside of the compartment. DC IN jack (page 11) 2 AC adaptor 3 AC outlet NOTE • After turning off the power, follow this procedure in reverse order to disconnect the AC adaptor. • Power will be automatically drawn from the AC adaptor if an AC adaptor is connected while batteries are installed in the instrument. Using Batteries This instrument requires six "AA" size, Alkaline (LR6)/ Manganese (R6) batteries, or rechargeable nickelmetal hydride batteries (rechargeable Ni-MH batteries). The Alkaline batteries or rechargeable Ni-MH batteries are recommended for this instrument, since other types may result in poorer battery performance. 4 Replace the compartment cover, making sure that it locks firmly in place. NOTICE • Connecting or disconnecting the AC adaptor with batteries installed may turn the power off, resulting in loss of data being recorded or transferred at the time. • Change the setting of the instrument according to the kind of battery you are using (Battery Type; page 42). When battery power becomes too low for proper operation, the volume may be reduced, the sound may be distorted, and other problems may occur. When this happens, make sure to replace all batteries with new ones or already-recharged ones. NOTE • This instrument cannot charge the batteries. Use only the specified charger device when charging. • Power will be automatically drawn from the AC adaptor if an AC adaptor is connected while batteries are installed in the instrument. 12 PSR-E253/YPT-255 Owner's Manual
