Radio Shack PRO-27 Scanner User Manual


 
After you program your scanner, you can protect it from accidental program

only controls you can use are SCAN, MANUAL, KEYLOCK, VOLUME/OFF, and
SQUELCH.
To turn on the keylock, press KEYLOCK until K/L appears on the display.
To turn it off, press KEYLOCK until K/L disappears.
