To lock out an "always busy" channel when in ALL SCAN mode, press SKIP when the radio stops at that channel, An X appears for one second on the screen to indicate a locked out channel and then scanning resumes. When a signal is received in either PSCAN or ALL SCAN mode, scanning stops at that channel. Press + or - repeatedly to step through the available channels one at a time, or hold down to scroll rapidly through the available channels at about 7 channels per second. Press REJ to activate the noise blanker circuit and reduce noise (e. g. The screen shows REJ to indicate that the noise blanker circuit is on. Local mode can be useful in areas of high radio noise; for example, close to cities. Press BAT to display the voltage of the battery supplying the radio in big digits on the screen; e. g. 12. 6V is displayed as 12, then after 1 second, the display changes to . 60. This cycle is repeated twice then the radio returns you to the most recent mode. You can use this only in ALL SCAN mode, if desired, to skip over a channel that is always busy.

The first screen displays the battery symbol (BAT) and the whole volts (12) reading for one second. After one second the next screen appears, showing BAT and the partial volts (. 60) reading for one second. This cycle is repeated twice.
