If the anti shock function is not required then it can be switched off by pressing the ANTI-SKIP button until the symbol ■ disappears from the display.

The sound will mute for approximately 1 second while the buffer fills, once filled the buffer will give approximately 45 seconds of protection against interruption of sound output, if the player is subjected to shock of over 45 seconds duration some interruption of sound output will occur, this is normal and to be expected, the sound will resume once the player has stabilized from the shock.

To turn this function off press the ANTI-SKIP button.
