DTMF Mute Timer:

This timer controls the amount of time the receiver entering DTMF stays muted. This timer needs

to be short so the instances of "Voice Falsing" does not mute the audio too long. Voice falsing is

the phenomenon that occurs when your voice sounds like a DTMF digit. If you set this timer too

long and the DTMF decoder falses, you will have a long gap in your voice (for the length of this

timer). The mute timer begins to run after the release of the DTMF key.

- This timer is programmed in 10mS Increments from 001-9999

- If a timer value of 000 is entered, your audio will be muted forever, so if you want it to be as

short as possible, enter 001

Reserved Timers:

Do not mess with these timers. These timers affect the communications from the main board to the

radio cards. Changing them will probably not help you but can cause the cards to be disabled

(changing them back and resetting the controller will fix accidental changes).

032..039 SPI Retry Timer, Port 1..8 (default value is 050, 500 ms)

040..047 SPI Timeout Timer, Port 1..8 (default value is 700, 7 seconds)

I/O Polling Timer:

This timer determines how often the controller checks to see if any of the input lines have changed

from high to low or low to high or if any analog alarm conditions have changed. If you want

quicker response to changes, shorten this timer. If you don't want to hear about changes that

happen more often than every minute or so, lengthen it to a minute. The default is one second.
