Using the LOCK Switch prevents unauthorized operation of the radio and will also prevent the station you are listening to from being changed. When the LOCK
switch is moved to its up 
position, the POWER button and TUNING controls are completely disabled. If the radio is on when the LOCK switch is moved to its up 
position, you will not be able to turn it off. If the radio is off, with the LOCK Switch in
its up 
position, you will not be able to
turn it on. This will also prevent it from being turned on by accident, when packed in a
attache case. To release the LOCK Switch, simply move the switch down.
