You will enjoy your scanner a lot more if you read the manual.
You are correct I surfed thru the PDF Manual somewhat but the terminology and meanings Baffle me .
Like ...DCS/CTCSS Rapid Decode and Recode. DMR Programming. IFX, IGR's What the Heck??
I Read the Manual to be able to put Frequencies into channels Still haven't figured that out yet after hours of reading..
You might want to consider buying software to assist you in entering frequencies. There are at least two programs available for you scanner, ARC XT by Butel and Proscan. With the cable you received with your scanner, the software program, and a premium subscription to Radio Reference you can easily program your scanner. Both ARC XT and Proscan offer free, 30 day trials to allow you to see which one works better.
