March 1999

Part No. 001-2009-600

4.3.4 DELETE REPEATER

Select the Repeater number to delete from this

Locality and press the Delete button.

4.4 TRANSFER

Figure 4-15 TRANSFER MENU

4.4.1 READ SETUP PARAMETERS

This menu selection has an equivalent icon in
the toolbar. This menu selection or icon reads
the contents of the EEPROM memory of a re-

peater and loads it into a buffer. The contents of the
buffer may then be displayed to show the programming
of the repeater.

NOTE: This button is only available if a Locality file is
loaded and a repeater is connected.

4.4.2 WRITE SETUP PARAMETERS

This menu selection has an equivalent icon in
the toolbar. This menu selection or icon sends
the contents of a Locality file to a connected re-

peater and programs the EEPROM memory in the Main
Processor Card (MPC).
