User's Manual

The third window is the VRS Advanced subsection (see Figure 8). This window is used
to enable/disable the Access Acknowledgment and Time-Out-Timer Tones and Repeater
Portable Priority Interrupt (PPI) as well as selecting the Time-Out-Timer duration. The
Time-Out-Timer duration may be set to 30, 60, or 120 seconds, or infinite. The infinite
setting should be used with caution, since damage to the transmitter could result from any
extremely extended transmission. It should be noted that the Repeater PPI feature must
be enabled to allow the multi-unit priority algorithm to function correctly when there will
be multiple VRS units on scene. The time between interrupts may be set to Fast (500ms)
or Slow (2 seconds) for conventional modes and Fast (500ms) or Slow (1 second) for
trunked modes.
