It appears it doesn't, according to the manual. That's a surprise considering it's a modern scanner.
Ignore the CTCSS or PL tone listed in the database. CTCSS stands for Continuous Tone Coded Squelch System, and PL is just another way to say it (it's Motorola's trademarked name, "Private-Line"). The way it's used on the RCMP system is that each frequency is used twice in the same geographic area. Repeater B7, 155.5500, is Strathmore; but Repeater B2, also 155.5500, is Cochrane. You will be able to hear both with your scanner, since you can't "lock out" B2 by entering B7's CTCSS tone. If you could enter the right CTCSS tone, you'd hear only those transmissions that originate from Strathmore crews.
