P-80
Factory Preset Recall
All dual mode, split mode, reverb, effect, touch sensitivity, tuning set-
tings, 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 40.
Troubleshooting
If you encounter what appears to be a malfunction, please check the following points before assuming
that your P-80 is faulty.
1. No Sound When the Power is Turned ON
Is the external audio device’s power switched ON?
Is the MASTER VOLUME control turned up to a
reasonable listening level?
Also make sure that the Local Control (page 33) is
ON.
2. The P-80 Reproduces Radio or TV Sound
This can occur if there is a high-power transmitter in
your vicinity. Contact your Yamaha dealer.
3. Intermittent Static Noise
This is usually due to turning ON or OFF a house-
hold appliance or other electronic equipment which
is fed by the same AC mains line as your P-80.
4. Interference Appears On Radio or TV Sets
Located Near the P-80
The P-80 contains digital circuitry which can gener-
ate radio-frequency noise. The solution is to move
the P-80 further away from the affected equipment,
or vice versa.
5. Distorted Sound When the P-80 is Con-
nected to An External Amplifier/Speaker
System
If the P-80 is connected to a stereo system or instru-
ment amplifier and the sound is distorted, reduce the
P-80’s [MASTER VOLUME], and/or the volume of
the external equipment to a level at which the
distortion ceases.
6. Noise is heard from the speakers or head-
phones.
The noise may be due to interference caused by the
use of a mobile phone in close proximity to the P-80.
Turn off the mobile phone, or use it further away
from the P-80.
● If “Scn” appears on the display an internal
malfunction has occurred. In this case,
contact your Yamaha dealer.
