MENU LOCK
Simply locking a channel will not deflect a determined would-be viewer. Re-installing
the complete channel list, for example, will bypass the channel lock. However, the
menus can be locked out of use too, to prevent this.
Display the Main Menu by pressing the “
M ” key, highlight Configuration, and press
“ SELECT ” key to display the Configuration menu screen. Highlight the Parental
Settings line of the menu (press “ ” key four times) and press “ SELECT ” key to
display the Parental Settings menu (after the PIN code has been entered). Here the
menu lock-out can be set and the PIN code changed.
With the Menu Lock line highlighted, use the “ “ or “ ” key to cycle the menu
lock setting through Disabled, Main Menu and Installation. The Main Menu setting
will lock out the complete menu system; the Installation Menu setting locks only the
Installation menu (see Advanced operation - Re-installation); and the Disabled set-
ting allows free access to any of the menus.
You must return to normal TV view-
ing by pressing the “
M ” key (three
times) to activate the lock. Now
any attempt to access the locked
menus will display the PIN request
window and the menus will only be
displayed on entry of the correct
PIN code.
Hint
If you want the channel and menu
locks to work efficiently and actual-
ly protect channels from access,
do change the PIN code from the
factory default. Make sure that you
choose a number that is not obvi-
ous to others but one that can be
remembered by you.
*
The same Parental Settings menu is
used to change the PIN code. With the
Set Lock Key line highlighted, press
“ SELECT ” key to display the Set Lock
Key window. This requests the new
four-digit code to be entered twice (for
confirmation) and the new code comes
in effect when you return to the Configu-
ration menu by pressing “ M ” key.
