Question:  I'm using Helixnet at our theater and I want to keep the users from accessing the local beltpack menus to make unauthorized changes.  Is this possible, I don't see any menu lock options in the beltpack menus.
Answer:  The beltpacks can be menu locked, you need to access this feature from the base station go to the menu button and press it in to activate the displays in menu mode.
From the leftmost display menu scroll to “Administration” and highlight
Then from the 2nd leftmost display menu scroll to  “Beltpacks” and highlight
Then from the 3rd leftmost display menu scroll to “Menu Lock” and highlight
From the rightmost display menu select “Lock All” and highlight and then press in the scroll knob associated with this display. 
The beltpack menus should now be locked, then the user presses the menu button the OLED display on the beltpack should say “LOCKED” in inverted highlighted text. 
To unlock the menus (again you must do it from the basestation) use the rightmost display menu and select “Unlock All”. 
Note:  As currently setup in v1.1 firmware the user can either LOCK or UNLOCK all the beltpacks on the powerline string.  It is not possible to menu LOCK or UNLOCK specific beltpacks on the powerline at this time.
