Turn on unit. (adjust squelch to mute, to silence if you want) Press MANUAL button. Press MANUAL button again to select the channel you want to program. Note the channel in the display. If there is a hyphenated symbol in the upper left corner the channel has been locked out. Press the LOCKOUT button once to remove the symbol or press the LOCKOUT button to lock a channel out. To find out if there is a frequency programed into that channel, press the PREVIEW button. Each digit of the frequency that is stored in memory will be displayed in the LED display. To program a new frequency into that channel, simply press the digits of the frequency you want, including the decimal point. Press the "E" keypad key to enter it into memory. If you get a "E" displayed in the LED display, the frequency was entered wrong, is not a valid frequency or is out of range for the scanner. Last but least, the scanner is not working properly. If the channel is active, (communications going over it) set SQUELCH to higher number, until you hear the communications or just noise. To set the SQUELCH, select a channel that has only noise and turn it down to the point the noise disappears. You make have to readjust it to your liking. Once you have the channels programed you can select the SCAN button to listen to all the channels or select the MANUAL button to listen to just one channel. If there are channels that you don't want to hear during the scan mode, go to MANUAL and select the channel you don't want to hear and press LOCKOUT button. Then press SCAN again it will only scan channels you want to hear.
You will have to get a owners manual to find out what the frequency ranges the scanner is limited to or search for someone that has one. http://www.scannerworld.com/content/product/model/OMBC145XL
