Front panel scanning

After channels have been added to the scan list, pressing the SCAN key brings up the SCAN
ACTION MENU. If no scan list exists then pressing the SCAN key will briefly display "No Scan
List. Use INSERT to add selection." The SCAN ACTION MENU contains the following items:




Pressing the INSERT key will add the selected channel(s) or pattern to the existing scan list.
Pressing the DELETE key will remove the selected channel(s) or pattern from the existing scan
list. Only the first occurrence of the selected item will be removed. If Channel 3003 appears in
the list three times and Channel 3003 is selected when the DELETE key is pushed, the first step
using 3003 will be removed (the remaining two will stay in the list).
When removing channels, no check is performed to determine if a channel is associated with a
pattern. Continuing the previous example of 3003, if 'mypat1' was comprised of channels '3003,
3033, 3911 and 3922' when the remove request for 3003 is made, it will not touch or look at
'mypat1' if the pattern is in the list. To remove 'mypat1' from list, select the channel pattern
'mypat1' and press the when DELETE key.
Pressing the STEP key will single-step through a scan list.
