To Use the Security Lock
 
 
If needed, you can use a security lock (available separately) to lock the oscilloscope 
to a fixed location. The method is as follows. Align the lock with the lock hole and 
plug it straight into the lock hole, turn the key clockwise to lock the oscilloscope and 
then pull the key out.
