delay occurs at the beginning of each transmission, this parameter should be as small as
possible to maximize system performance.
The Data Mute line is also asserted at the beginning of this delay. If the console cannot
mute fast enough to block FFSK packet noise, the value of this parameter can be
increased to provide more time. Increasing the value of this parameter slows down the
response time of the entire system.

Note
If a poll cycle has started, all stations will be polled before the M26
starts checking the status of alerted stations. Even though the
actual alert time will NOT change, longer than expected delays in
“PA Ready” are possible, especially with a longer key-up delay
setting.
To minimize “PA Ready” latency during a poll cycle, we
recommend that the “Stations Per Poll Time” be set to 1, and the
“Poll Time” be set to time required to compete a full poll cycle
divided by the number of M6 stations. For example:
Poll Time - 0:06:00.00 (Hr:Min:Sec:Hun) Ö (6 minutes are set)
Stations Per Poll - 1 (0 = All) Ö (one station per poll)
This example shows settings that allow 10 stations to be Polled
within a one hour interval at a rate of one station every 6 minutes.
With a 1 second key-up delay time programmed, the “PA Ready”
latency, due to a poll cycle, will only be 2 seconds longer during
the poll cycle (i.e. two seconds per station polled longer).
