Hold in button 6 while switching on the radio unit.
the display will change from lock 10 to CODE.
Insert the radio code by repeatedly pressing button 1 until the first
number of the code appears on the display.
press button 2 until the second number of the code appears inthe display.
repeat the process on buttons 3 &4 to complete the code.
when the code is entered correctly press button 5 and the radio should unlock.
It works very well
