You don't want accidental change of frequency or other setting in the middle of a 
performance, do you? Any miss-operation during a live performance can be easily 
avoided thanks to the LOCK function. With the LOCK function ON no further change 
of setting is allowed until the Transmitter is unlocked. To access the LOCK Menu, 
press the CH/ON key four times and then press the SELECT key to lock or unlock
 the Transmitter Settings. Your choice of setting will automatically be saved into the 
Transmitter in a few seconds. The blue display shows "lock" and "unlock" depending 
on the operating mode.
