Notes:
1. 1.6 mm below seating plane.
2. It is essential that a bypass capacitor 0.1 µF be connected from pin 6 to pin 7 of the receiver. Total lead length between both ends of the capacitor
and the pins should not exceed 20 mm.
3. Pins 1 and 4 are electrically connected to the conductive housing and are also used for mounting and retaining purposes. It is required that pin 1 and
4 be connected to ground to maintain conductive housing shield effectiveness.
