The info below is directly copied from the owners manual. Other then the A - J info in step 1 in the second part, this appears to program similiar to the Pro-2052 scanner which I have a
Programming Shortcut for in Radio Reference Wiki. On the 2052 the A -J would be numbers 1 - 10 (actually 1 - 20) because it has 20 banks.
Setting the Scanner to Trunking Programming Mode
You must set the scanner to its trunking programming mode before you can program
channels and enter trunking frequencies.
If you are in conventional scan mode:
1. Hold down TRUNK. The scanner beeps twice and BANK and TRUNK flash.
2. Select the trunking bank you want to program.
If you are in trunking scan mode:
1. Press TRUNK to return to conventional mode if you have been monitoring a trunking bank.
2. Hold down TRUNK. The scanner beeps twice and BANK and TRUNK flash.
3. Select the trunking bank you want to program.
Note: When you set the scanner to its trunking programming mode, you cannot select
channels in other banks.
