When Auto is selected the unit displays the screens to
set times for switching. See Figure 3-14.
With the cursor on 1)Map A, press Enter to activate
the selection fields for hour, minute, and second. The
cursor first moves to the hour position. Type in
numbers and press Enter. The selected hour is entered
and the cursor moves to the minute position. Set
minutes by the same method as used to set the hours.
If a number is mistakenly entered, pressing Cancel
interrupts the editing process. The procedure can be
restarted to accept correct entries.
When using one digit numbers, the number appears in
the first of two spaces. Upon pressing Enter, the
system moves the single number to the second space
and fills the first with a zero.
After editing Map A, press Enter to record the Map A
settings and activate the selection fields for Map B. Use
the same operation to edit switching time for Map B.
After settings for both Maps A and B are completed,
press Cancel to returns to 3)MAP XCHNG.
Continue with standard operating procedures.
When ESF is used with an FDL channel between units, the
units automatically coordinate the automatic map switch by
sending a map switch command from end-to-end over the
FDL. Only one end needs to be set to Auto for this to work.
