Problem Possible Cause and Solution

The P-85 does not turn on.

The P-85 has not been plugged in properly. Securely insert the female plug into the

jack on the P-85, and the male plug into a proper AC outlet (page 11).

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-85. Turn off the mobile phone, or use it further away from the P-85.

The overall volume is low, or no sound is

heard.

The Master Volume is set too low; set it to an appropriate level using the [MASTER

VOLUME] control (page 11).

Make sure a pair of headphones is not connected to the headphones jack (page 13).

Make sure that Local Control (page 28) is ON.

The pedal has no effect.

The pedal cable/plug may not be properly connected. Make sure to securely insert

the pedal plug into the SUSTAIN/PEDAL UNIT jack (page 12).
