Revision/Version
The Revision/Version is displayed for the repeater
modules. The format for all modules is R.V. (revi-
sion.version). The MPC information also includes the
software release date and the repeater serial number
(see example in Figure 5-19).

Mode Select
The Mode Select screen places the repeater either
in the normal mode or the test mode. In the Normal
mode the repeater operates as a normal repeater.
In the Test mode the repeater transmits a test
word. This test word is the Test Mode ID set up in the
Setup Parameters (see Table 5-1). While in the test
mode the repeater is “busy”, therefore it is important
to place the repeater in Normal mode when the test
mode is no longer required.
