Locking and unlocking channels
Locked channels appear in the channel list but don’t appear
in the video window when you scan through the channels.
1 Choose Channel Setup from the Setup menu.
2 Choose from the Connection pop-up menu the connection
for the channel list you want.
Note: You can lock or unlock channels only in the channel
list for the connection that’s currently chosen. For example,
if you lock channel 15 in the antenna channel list, the
channel will not be locked in the cable channel list or the
HRC cable channel list unless you name it in those lists.
3 Select the channels you want to lock by highlighting them.
To select several channels in a row, hold down the Shift key
and drag. To select channels scattered throughout the list,
hold down the Shift key and click all the channels you want
to lock.
You may have to scroll to see all possible choices.
