Mostly at the Pub after screwing up my exams
I know this probably isn't very relevant now as every one is using digital but i just though that someone may find it useful. I couldn't find this on Digital World even though it's probably somewhere in the archieves or it was and has been deleted so i though i'd add it anyway.

Yes i found a fully working CFT2100 in a skip this morning, thats why i needed these codes to see if it still worked.

F 1= Dynamic Diagnostics
--------------------------------
This mode permits the monitoring of the descrambler circuit, the FM receiver and the FM signal.

Digit 1 = State of descrambler
C = Clear channel
S = Scrambled channel
B = Barker channel
- = Disconnected

Digit 2 = State of FM Receiver

O = FM Data "OK"
E = FM Data "ERROR"

Indicator "A" lights when unit sees a purchasable event
Indicator "B" lights when unit is addressed over the FM Data


F 2 = Serial number & firmware version
-------------------------------------------------
1st Number = Place made
00 = Japan
01 = Tawain

2nd Number = Year made

11 = 1991
12 = 1992
13 = 1993
14 = 1994

3rd Number = Month made

20 = Jan, 21 = Feb, 22 = Mar, 23 =Apr, 24 = May,

25 = Jun, 26 = Jul, 27 = Aug, 28 = Sep, 29 = Oct,

2A = Nov, 2B = Dec

11th Number = Firmware versions

F 3 = Firmware Mode
--------------------------
I = Internal firmware

R = Expansion ROM version

F 4 = STATE diagnostic Mode
------------------------------------
Digit 1 = State of FSK data

R = Receiving Data

- = Idle

T = Transmitting Data (2 way only )


F 5 = STATUS Diagnostic Mode
--------------------------------------
Alternating display of the Frequency & Level. There are 16 different levels ( 0 - 9, A - F)

F 9 = Clock Function
--------------------------
Toggles Clock on & Off

F 0 = Error Codes
----------------------
EO = Normal

E1 = Reset timeout or good FM Packet not received

E4 = Illegal Converter

E5 = Converter has default address, initialize again

E7 = Faulty ROM or wrong initialization process

E8 = Site code error

E9 = Bad checksum pattern in non-volatile memory

EA = Invalid serial # entry (Wrong checksum)


Hope this might help someone, who is still playing with analogue.
