2.4.3 Control Access to Squelch Modes
The squelch modes are among the more complicated editing and configuring options; the system
supports an access control scheme that allows you to enable access only to modes that your
organization or specific mission needs.
Command L4-9 is used to restrict user access to squelch modes, editing, and select options, this
can be used to simplify operation and reduces the potential to mis-configure the system. The
access restrictions operate according to the following table:

The user may edit the permissions as follows:
Toggle permission ( @ = enabled, A = disabled
move backward/forward through the restriction screens ( ← → select column in table)
step up/down through column entries ( ↑ ↓ select row in table)
accept the entry and exit
abandon the entry and exit
Note you may only restrict editing of a selected value in analog modes.
2.4.4 Control Editing of Memories
In some cases it may be advantageous to set up a memory, and then ensure that the configuration
of that memory cannot be changed by the user. Command 4-4 provides this function. The
currently selected channel memory - as determined by the front panel switch positions -may be
enabled or disabled for editing. The command screen appears as follows:
