Do we need the G up there and what does the G do? I know it is for global but what does it actual do?
.
When you see the
G in the display by itself, it indicates that the Global
mode for attenuation is in effect, and
all attenuation is turned off globally... there is no attenuation of
any signal being received by the scanner (this will override any individual attenuation settings).
When the
G is in the display and you press ATT you'll see
GA in the display. That indicates that the Global
mode for attenuation is in effect, and attenuation
is now turned on.... to attenuate (or reduce) the signal strength by 20dB for
all signals that the scanner is receiving (this will override any individual attenuation settings). To turn off all attenuation while in the Global mode, press ATT to return to just the
G
You can also attenuate individual signals while not in the Global mode.
To exit the Global mode, press FUNC + ATT. The
G (or GA) is now absent from the display. At this point, you can choose to turn on attenuation for individual conventional channels, or trunked systems by pressing just the ATT key when holding on that item. Now,
just those items
and no others will be attenuated. When stopped on one of those items, just the
A will show in the display.
If you have individual items set for attenuation and then press FUNC + ATT to return to the Global mode, that will over ride any individual settings for attenuation on those items, and the scanner's attenuation will now function globally again as detailed in the first 2 paragraphs above.
At this point, if you were to exit the Global attenuation mode and return back to the individual attenuation mode by pressing FUNC + ATT, any individual items that were set for attenuation when you were last in the individual settings mode, will still be as you set them... in other words, being in Global mode overrides any individual settings that you have made, but it does not erase them.
