Yamaha P-120 Owner's Manual - Page 44

Factory Preset Recall All dual mode, split mode, reverb, effect, touch sensitivity, tuning settings, and the settings affected by the Backup Functions can be restored to their original factory preset values by holding the C7 key (rightmost key on the keyboard) while turning the [STANDBY/ON] switch ON. This also erases all user song recorder data, and sets all Backup on/off settings (F9) to "OFF". NOTE • The factory setting list is found on page 49. Troubleshooting If you encounter what appears to be a malfunction, please check the following points before assuming that your P-120/P-120S is faulty. 1. No Power Is the AC adaptor's DC plug connected to the main unit? Is the AC cable plugged into the AC adaptor and an AC wall outlet? Please check all connections. (page 10) 2. No Sound or Sound Output is Low Is the MASTER VOLUME control turned up to a reasonable listening level? Make sure a pair of headphones is not connected to the headphones jack (when the SPEAKER switch is set to the "NORMAL" position). If the SPEAKER switch is set to the "OFF" position set it to "NORMAL" or "ON" (page 11). Also make sure that the Local Control (page 38) is ON. 3. The speakers do not switch off when a pair of headphones is connected. The SPEAKER switch may be switched "ON". Set the SPEAKER switch to the "NORMAL" position (page 11). 4. The P-120/P-120S Reproduces Radio or TV Sound This can occur if there is a high-power transmitter in your vicinity. Contact your Yamaha dealer. 5. Intermittent Static Noise This is usually due to turning ON or OFF a household appliance or other electronic equipment which is fed by the same AC mains line as your P-120/P120S. 6. Interference Appears On Radio or TV Sets Located Near the P-120/P-120S The P-120/P-120S contains digital circuitry which can generate radio-frequency noise. The solution is to move the P-120/P-120S further away from the affected equipment, or vice versa. 7. Distorted Sound When the P-120/P-120S is Connected to An External Amplifier/ Speaker System. If the P-120/P-120S is connected to a stereo system or instrument amplifier and the sound is distorted, reduce the P-120/P-120S's [MASTER VOLUME], and/or the volume of the external equipment to a level at which the distortion ceases. 8. Noise is heard from the speakers or headphones. The noise may be due to interference caused by the use of a mobile phone in close proximity to the P120/P-120S. Turn off the mobile phone, or use it further away from the P-120/P-120S. G If "Scn" appears on the display an internal malfunction has occurred. In this case, contact your Yamaha dealer. 44 P-120/P-120S 42
