Uniden Scanner Test Modes for the HP Series scanners

From The RadioReference Wiki

Before We Begin

  • The usual warnings apply; RR is not responsible if you damage your scanner, use at your own risk, etc.
  • Some of these cause the scanner to lock up. If this happens remove the battery / power, put it back in then turn it back on. Make sure your scanner is backed up using your software of choice before you do any of this.
  • Power down to exit unless stated otherwise
  • If you turn the BCD536HP off then on to reset it, you might get the infamous Nothing To Scan message. If you do, select Write Data to Scanner.
  • With the SDS100 you may need to try more than once to get it to work.
  • You can find support to discuss these at the Uniden Tech Support Forum

The "Calibration" function will set the accuracy of your finger's input to the touch screen....

Once you have selected the "calibration" menu button, you will see small circles appear on the screen. Touch carefully and directly on the circles as they appear. There are 5 circle targets to touch. The first 2 turn a very light yellow color after you touch them, and the next 3 show a small red dot where your touch was registered.

After touching all of the calibration circles that appear, touch anywhere on the screen and then choose "Save" from the next page, or "re-try" if you want to repeat the calibration.
