Notes:
1. Exposure to extreme light intensity (such as from flashbulbs or spotlights) may cause permanent
damage to the device.
2. CAUTION: It is advised that normal static precautions should be taken when handling the encoder
in order to avoid damage and/or degradation induced by ESD.
3. Proper operation of the encoder cannot be guaranteed if the maximum ratings are exceeded.
