6:STEPS
Your UBC3300XLT is programmed with default step sizes for each frequency range (see page 1). Steps are important if you are interested in using the VFO to tune off from a frequency programmed into memory or if you wish to program a frequency that the default step size will not accept.
7:MODE
Default Auto receive modes are also programmed into memory. AM for aircraft, for example. You can change the default settings on a
2:TRUNK
Choose the Trunk bank. The following options are available for the selected trunk bank only. Repeat using a different trunk bank, if necessary.
1:TRUNK TYPE
You will need to assign the correct trunking type for the bank you are about to program. If you want to listen to a Motorola Type I system, you will need to use this Menu option to assign the same. If you do not know the type of trunking system you are about to monitor, refer to the guide included with the scanner or check out www.bearcat1.com.
Note: Some trunking systems require that you know the channel order. In these cases you will also need to start programming the trunked system at the start of the bank. The scanner defaults to the most common type of trunking system, Motorola Type II 800.
