Level 4 Key Scope: Main and Guard
You may restrict user access to the Squelch modes. The restricting hierarchy is as follows:
• squelch mode select restrict – limit which squelch modes may be selected.
• squelch mode edit restrict – limit which squelch modes the user may edit the value of
• squelch mode value restrict - limit the range of values for available in a squelch mode
These features are described in the sections below. The editor operates as follows:
Edit Keys
move backward/forward through the restriction screens
step up/down through the parameters for each screen
Toggle the state of the displayed parameter: enabled @ / disabled A
accept the entry and exit
abandon the entry and exit

Modes appear for the user to select when editing Squelch Modes (L1-9, or in L2-1, or L2-7).
Figure 3-46. The Screen to Set Available Squelch Modes for Analog Receive
Here, the user can restrict the individual Squelch Modes that will appear to the user in the Analog
Squelch mode selector for receive, the same can be done for analog transmit.
L4-9.2. Restrict Editing of a Squelch Mode Value
This screen allows you to restrict which Squelch Modes can have their values edited by the user, a
restriction here will still allow the mode to be selected for use, but the value cannot be changed.
