3D EFFECT FUNCTION
The 3D pin controls PT2353H’s 3D effect function. It toggles between turning the 3D effect function ON
and OFF. When the 3D effect function is enabled, the 3D LED is displayed. When the PO pin in low
state the 3D function will backup and both 3D effect and 3D LED are inhibited.
POWER CONTROL
PK (Pin 14) is the PO Control Pin and is used to toggle between activating and deactivating the PO pin
(Pin 15). The power amplifier MUTE or Standby status (ON or OFF) may be controlled by connecting
the external power amplifier device to the PO Pin.
