Backing Up Your Scanner

While it doesn't happen often, it is possible that applying a firmware update could affect some of your scanner's programmed settings or systems. We recommend you make a full backup of your scanner's programming and configuration before you apply the update. Follow these quick steps to make a backup of your BC246T programming using Uniden Advanced Scanner Director (UASD):

  1. Install (if necessary) and run UASD.
  2. From the main page, select "Scanner View".
  3. At the top of the window, select Setup --> Options.
  4. Set the COM port to the port you've connected the BC246T to and select the baud rate that matches your scanners XFer Information-->PC Control setting and then click OK.
  5. Select "Connect to Scanner" from the left panel.
    • The software will begin to read the contents of your scanner.
  6. When UASD finishes reading from the scanner, select "Save" at the top right side of the window.
  7. Make sure the check boxes next to "Save Configuration as", "Save Selected Systems", and "Replace existing files with same names" are checked, then enter a name for your configuration in the text box next to "Save Configuration as:", then click OK.
    • Since this update does not change the major version number, you do not need a registration code to apply this update.

Applying the Update

Download, unzip, and install Run the BC_VUP3 utility and follow the on-screen instructions.

Update Troubleshooting

Follow these tips to troubleshoot any update problem you encounter:

UASD After the Update

While you can continue to use UASD after the update, note that the new features incorporated into this update have not yet been applied to UASD. So, new settings are only available through direct entry at this time.

Motorola 800 Custom Band Plan (Rebanding)

This update adds the ability to create a Motorola 800 MHz system using a custom band plan. When you create a system that has been rebanded to use the frequencies newly added for use by the FCC, you have the option now of selecting 800MHz Custom as the Motorola system type.

Once you create the system, you can set the custom band plan as follows:

  1. In the Edit Sys Option menu, select Edit Band Plan.
  2. Select the band plan entry to edit.
  3. Set each of the following entries for the band plan:
    • Set Base Freq (Upper and Lower)
    • Set Offset
    • Set Spacing
For standard rebanded systems, you need to set Band Plan 1 and Band Plan 2 as:

Band Plan Base Freq (Lower) Base Freq (Upper) Offset Polarity Spacing
1 851.0250MHz 854.0000MHz 440 + 25 kHz
2 851.0125MHz 868.9875MHz 0 + 25 kHz

Close Call Do-Not-Disturb (Close Call DND) Operation

This update added the Close Call DND mode to your scanner. In this mode, you can use the Close Call feature without having audio interrupted every 2 seconds. The scanner will suppress Close Call checks whenever you are receiving an active transmission.

To select Close Call DND, repeatedly press F+HOLD until the scanner displays Close Call DND.
