Firmware version installed on the device
To know the system firmware version it is necessary to enter in programming mode (follow the instruction explained
in the previous paragraph) then insert the parameter number 300 follow by the # (pound key) digit. It is a special
parameter, for signaling only and it has not an associated value.
AA-539 will play 2 series of beep tones. You must count the number of beeps played. This number is the firmware
version installed. The firmware version is always composed by 2 digit, the first one is the number of the first series
of beep, the second one is the numbers of the second series of beeps. A pause of 1 second is inserted between
the first and the second series of beep. At the end of the second series of beep AA-539 will play a confirmation
long beep.
For example if the firmware version installed is 2.9, after AA-539 received the parameter 300, it will play this
sequence of beep: 2 beeps, 1 second pause, 9 beeps, one second pause, confirmation long beep.
Another way to know the firmware version installed is as follows: Turn off AA-539, wait for about 30 seconds and
turn on AA-539. Count the number of flashes issued from the AA-539 led. AA-539 will issue 2 series of flashes.
You must count the number of issued flashes. This number is the firmware version installed. The firmware version
is always composed by 2 digit, the first one is the number of the first series of flashes issued, the second one is the
number of the second series of flashes issued. A pause of 1 second is inserted between the first and the second
series of flashes.
For example if the firmware version installed is 2.9, after power on AA-539, it will issue this sequence of flashes: 2
flashes, 1 second pause, 9 flashes.
