Q: How do I use a tail message to report a power failure?
Let's say we want a message to be appended to the Repeater Initial and Normal ID Messages while the repeater is operating on battery power. We have wired our Logic Input #4 to detect a power failure.
We program User Message #1 with the speech we want to hear, like this (see page 6-63):
; Say "power fail thirteen point two volts" or whatever the actual voltage is
99 33 0015 9960 0148 0766 9852 01 00 9960 0150 *
You can test this message with this command:
99 34 0015 *
