How do I switch between operating modes on the ViewStylus ACP501?

Toggle between "iPad Mode" and "Capacitive Mode" by tapping the top touch sensor of the stylus. The current mode is indicated by the LED color.


Steps:

  1. Locate the Sensor: Find the touch-sensitive area at the tail end (top) of the ACP501.

  2. Tap to Switch: Gently tap the top with your finger to cycle through modes:

    • Green Light (iPad Mode): Designed for iPad series (supports palm rejection).

    • Blue Light (Capacitive Mode): Designed for general capacitive touchscreens (e.g., iPhone, Android devices, or ViewBoard).

  3. Confirm Status: If the LED is off, tap once to wake up the stylus before switching.


Notes:

  • Tip: If the LED flashes red, the battery is low and requires charging.

  • Note: A "gentle tap" is sufficient; applying excessive pressure to the sensor is not necessary and may affect responsiveness.
