The Yamaha SYSTEM60II is an electro-acoustic guitar with the following features: SYSTEM60 II system, piezo pickup, master volume control, pickup level control, output jack and power switch.
This is the Japanese owner's manual (取扱説明書) for the Yamaha SYSTEM60II electric acoustic guitar. It explains only the electronic part of the instrument; for the guitar body itself, the manual refers the reader to the separate acoustic guitar owner's manual. The booklet opens with safety precautions and symbol explanations, then describes the parts and controls.
The control section covers the master volume (VOL), the pickup level controls MAIN, TREBLE and BASS for the main and sub pickups, the push-in knob design, and the battery check lamp. A battery replacement procedure is given, followed by a specifications list covering the SYSTEM60 II monaural 3-way system, the contact pickup, output jack, output impedance, DC 9V power and battery life. Battery precautions are repeated in French, English and Italian. This manual is written in Japanese.

The battery is pulled out toward you through the sound hole together with the snap cable, then the snap cable is detached from the battery. To fit a battery, attach the snap cable to it and push it, with the cable, into the holder through the sound hole.
It lights when the battery is worn out and needs to be replaced with a new one. As the battery nears the end of its life, the guitar sound becomes distorted or the volume no longer rises.
If all of the pickup level controls (MAIN, TREBLE and BASS) are set to "0", no sound is output even when the master volume (VOL) is raised.
It uses a DC 9V S-006P battery (6F22 or 6LR61), and battery life is about 50 hours when manganese batteries are used, depending on conditions of use.
