PAMS UI Module UE4 Technical Documentation Display Backlighting is provided by LEDs, three LED on right and three on left side of display. LEDs are compatible with CL270–YG and those are side illuminating. Light is on when LIGHT–signal is in HIGH state.

PAMS Technical Documentation UI Module UE4 Speaker The speaker is sealed to A–cover and UI PCB with silicon gasket. With that the frequency response is more constant. Speaker needs 6pcs of 1.2mm holes under component for leaking sound pressure into RF–section through UI module and 7pcs of 0.9mm holes left corner of UIM to leak from RF–section back to up cavity of phone. RF–section between UI module and engine acts like sound cage which is known.
