Flash (dual LED)
The dual LED flash consists of two high power white LEDs for use as a camera flash, torch mode and video
light. The torch and video light have significantly reduced power compared to the image capture flash. A red
indicator light is also present for privacy reasons to indicate when an image is being captured or a video
recorded.
Illumination
Key illumination
Only MENU or HOME key illumination is supported and is handled by RGB 3 channel LED driver NJOY-3. 2 white
LEDS, V2420 and V2422, are used for MENU key illumination. These LEDs are connected in parallel to R output
of NJOY-3 LED driver.
Charging illumination
2 white LEDs are used for charging indication.
One white LED (V2505) is connected to EM ASIC “ChInd” pin and blinks only during dead battery USB charging
in intervals of 1.5s. This LED is OFF when the charging is taking place under SW control.
The second white LED (V2506) is connected to B output of NJOY-3 LED driver and glows for indicating USB
charging controlled by SW. This LED is OFF during dead battery charging.
