Only the items useful when servicing the PDP-434PU/PDP-504PU are described here. How to enter Factory mode using the remote control unit Please refer to the technical documentation (Service knowhow).
  • Page 61 Data on temperature (INFORMATION-TEMPERATURE) The data on the current temperatures are displayed. The temperature at the PANEL SENSOR ASSY of the PDP-434PU/PDP-504PU is indicated as the TEMP 1 value (000-255), which should be converted using the following formula: 0.65 × TEMP 1 value - 52 Current temperature (°C)
