If the correct anti-theft code has been entered the display will change to an FM frequency and the radio can be used. If the incorrect code is entered SAFE is briefly seen in the display changing to 1000 again and one additional attempt to enter the correct code is possible.
Unlocking a locked radio (SAFE on the display)
The radio becomes electronically locked after two incorrect code entries. To unlock the radio so that the correct anti-theft code can be entered the radio must remain powered on for a specified time. Use the following procedure to do this.
