Revision/Version

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 3-2). 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.
