Setting Up Be sure to read "Power supply" (page 2) and "Batteries" (page 2) in the "PRECAUTIONS" before you begin. Improper WARNING handling may result in product failure, overheating, fire, or other problems. Although the instrument will run from either an AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible, for optimum eco-friendly operation.  Using an AC Adaptor  Using Batteries Connect the AC adaptor to the DC IN jack and an AC outlet following the order of (1), (2) in the illustration below. When disconnecting, turn the power off and disconnect the AC adaptor in the order of (2), (1). AC adaptor (2) AC outlet (1) DC IN jack WARNING • Use only the supplied or the specified AC adaptor (page 23). Use of other adaptors may result in product failure, overheating, fire, or other problems. Yamaha cannot be held responsible for damage caused by improper use even if the instrument is under warranty. • If the plug is removable, make sure to keep the plug attached to the AC adaptor. Using the plug alone can cause electric shock or fire. • If the plug is removed accidentally, slide the plug into place without touching the metallic parts, and then push the plug in completely until it clicks. To avoid electric shock, short circuit, or damage, also be careful that there is no dust between the AC adaptor and plug. Plug Slide the plug as indicated The shape of the plug and outlet differ depending on the particular locale. (Six commercially available 1.5V "AA"-size batteries are required) Usable batteries: alkaline (LR6), rechargeable nickel-metal hydride batteries (rechargeable Ni-MH batteries), Manganese (R6) • The instrument itself 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. • Alkaline or rechargeable Ni-MH batteries are recommended because the instrument may consume a large amount of power. 1 Make sure that the power of the instrument is off. 2 Put the instrument upside down on a soft cloth, and open the battery compartment cover located on its bottom panel. * The illustration shows the NP-35. 3 Insert six batteries by following the polarity markings on the side of the compartment. 4 Close the battery compartment cover. NOTICE • When battery power becomes too low, the instrument may not function properly. When this happens, make sure to replace all batteries with new ones or already-recharged ones. • Connecting or disconnecting the AC adaptor with batteries installed may turn the power off. Use caution, as any data you are recording will be lost when the power is turned off. NP-35, NP-15 Owner's Manual 9
