Miss your old 41C/CX four tone BEEP? Recreate it in the 48 series with this.

<< 630 .25 790 .25 400 .25 630 .25 BEEP BEEP BEEP BEEP >>

'BEEP4' STO

I determined the frequencies by trial and error before parting with my 41CX.

For the 50g, replace 790 with 820. Don't know why that is.

The 41's BEEP is TONE 7, TONE 5, TONE 8, TONE 7.
According to the Wickes book on synthetic programming the frequencies are as follows:

TONE 7 = 629 Hz
TONE 5 = 394 Hz
TONE 8 = 788 Hz
TONE 7 = 629 Hz

So you're quite close. ;-)
The book also says that the duration of the standard tones is 0,28 seconds.
