Note.
OE pin = HIGH : Specified frequency output.
OE pin = LOW : Output is high impedance, oscillation stops.
#3 is connected to the cover.
To maintain stable operation, provide by-pass capacitor
with more than 0.1 μF at a location as near as possible to
the power source terminal of the crystal products
(between VCC - GND).
