control signal
By briey pressing the buon the acousc
single-pulse indicaon is acvated respecvely
deacvated. When acvated, the loudspeaker
symbol is displayed and each GM-tube pulse
triggers a brief sound.
This seng can be changed in the menu
„Acouscs“, where it is possible to reduce the
pulse rate of the background radiaon in such
a way that only the tweneth GM-tube pulse
will trigger a sound. Addionally, a funconal
control signal sounds approx. every two min-
utes, indicang the GammaTwin is correctly
