Uniden Digital AGC Tweak Procedures

Here is the procedure for tweaking the AGC digital/analog settings for the BCD396T and BCD996T.

NOTE! You MUST have digital AGC set to ON for the digital tweak to work. To adjust the analog AGC, Turn the digital AGC OFF, Make sure analog AGC is ON, then follow the same steps below, but be sure to remember to turn digital AGC back ON when finished. All settings are saved, even when you cycle power, and the option is no longer available until you access it again.

1. Power on the scanner while pressing the HOLD/RESUME button.
   • On the BCD396T you will hear two beeps to indicate that the AGC tweak menu is enabled. On the BCD996T the display will flash red and green to indicate that the AGC tweak menu is enabled.
2. Press in the function knob. WHILE THE F IS FLASHING IN THE UPPER LEFT OF THE DISPLAY, press the volume knob ONCE.
3. The text "P25 RES TIME" appears in the bottom line of the display, with +0 next to it.
4. Rotate the scroll knob to adjust the setting. -7 is the recommended setting (may vary per system)
5. Once set to the desired level, press the scroll knob.
6. Press the scroll knob again, and while the F is flashing, rotate the knob. P25 REF GAIN now appears, also with a +0 to the right of it.
7. Rotate the scroll knob to adjust the setting. +3 is the recommended setting (may vary per system)
8. Once set to the desired level, press the scroll knob.

ADDITIONAL NOTE: If the above step #6 doesn't work for switching from P25 RES TIME to P25 REF GAIN try this after you've adjusted your P25 RES TIME: (This information provided by emt_531 on the forum.)

2. Press down on the scroll dial TWICE
3. (While continuing to hold in the FUNC button) Rotate the scroll dial until you see P25 REF GAIN
4. Press down once on the scroll dial to select P25 REF GAIN.
