∗1: Shutdown (SD) is a protective operation controlled by the microcomputer, and you can turn on the unit again using the remote control unit.
Power-down (PD) is a protective operation activated by the circuitry and can be reset after AC power is off for about 1 minute.
∗2: Refer to the service manual of the PDP-436PU or PDP-506PU.
∗3: Only for EU and IRD model,
∗4: Only for J model,
∗5: Except for US model.
∗6 Only for one-body model,
