Battery
Note 1: Select R5 and R6 for the correct level to test the ion chamber. The voltage level on pin 1 (TSTART) must be
9V
+
2: Select R9 to reduce sensitivity during the timer mode.
3: R3, R4 and C1 are typical values and may be adjusted to maximize sound pressure.
4: C2 should be located as close as possible to the device power pins.
5: Route the pin 8 PC board trace away from pin 7 to avoid coupling.
