GASSONIC OBSERVER-i
88
When doing the "7-UP" the output level will default to the maximum level. This means that the sound
level displayed will be at the maximum amplification.
There are now two scenarios:
1. The sound level is between 80 dB and 110 dB.
This value can be directly saved as the sound-source reference level. Activating the ENTER-switch will
save the sound-source reference level. The unit will display "DONE" for 3 seconds, which will indicate
that the sound-source sound level reference was set to the dB level shown on the display and there
after returns to normal operation (see flow chart 1).
NOTE: I
f no switch is activated for an interval longer than 1 minute, the unit will return to
normal operation without setting the new reference.
2. The sound level is lower than 74 dB.
If the sound level read-out is lower than 74 dB and the display is flashing, the sound-source tower
should be replaced with a new tower, and the sound-source calibration procedure should be repeated.
