tone. Only in rare instances will you need to adjust the default settings. The condition to return to control channels depends on whether a signal is present or not.

:CNTRL CH ONLY

(TYPE 1/TYPE 2 800, 900)

With this mode you will be able to track Motorola Type I and II 800 and 900 MHz trunked systems by simply entering the control channel which manages the trunked system. You will not have to program the voice channels. There are 4 channel plans which you can select from.

3:SYSTEM OPTION

1:DIMMER

Allows you to change the brightness of the display. Also you can change the lighting length of time.

2:SCREEN MASK

Screen Mask allows you to limit what appears on the display to the alpha tags that you have set for a channel along with a few function icons. Screen Mask removes the frequency, receiving mode tone data and signal strength bars. This mode is particularly useful in public safety vehicles where "information overload" is already a problem. Screen Mask does not work in Search mode.

3:KEY BEEP

Use this function to turn 2:OFF the keypad acknowledgement beep. The default setting is 1:ON.

4:ENTER LOCK

Use Enter Lock to prevent accidental re-programming of channels, tone (CTCSS/DCS) and talkgroups entered into memory. The default setting is 2:OFF.

5:PC CONTROL

Use this function to set the transfer speed (baud rate) at which your personal computer (PC) communicates with the scanner when downloading information into your scanner using the Uniden’s E-Scanner software. See page 80 for details.

6:CLONE

You can clone all the programming, including frequencies, talkgroups and alpha tags as well as bank settings and other parameters from one BC250D to a BC785D or another BC250D.
