Locking and Unlocking a Message
Important messages can be locked to ensure their 
safekeeping for later review. A locked message cannot be 
deleted until the message is unlocked. 
Press ƒ, then press fi, to toggle the current 
message between LOCKED and UNLOCKED. 
The   icon flashes in the display when a message 
is locked.
Note: 
If your message memory is full and a new message is 
received, any unlocked messages that have been read will be 
deleted.
