I couldn't to configure the Speed Dial Function for Programmable Keys on DT730 8LD DESI Phone. Configuration steps:
1. CM 12, Y=24, A mode
-> You have 16 DSS keys on Page 3 & Page 4 of the phone
2. CM 94, 01 00 1 02
-->(1000-Slot Memory Block Number 01, 10-slot memory start number 00, effective for programming the dialed number from station, 02 memory block)
3. To configure key
--> Press Feature key --> scroll to page 3/4 --> choose 1 SPD key --> Press number --> Press Feature key again to confirm
Is there any missing step?

I also tried another way for configuration this:
1. CM 73, 00 00 1 04
2. CM 90, Assign F11XX to key 02 to 24
3. Configure key (Feature--> Key SPD --> number --> Feature)
I can configure from Key 02 to Key 16. No effect from Key 17 to 32.
Which command should I use for configure Key 25 to 32 as CM 90 only shows up to key 24?
Any advice for me about this case?

Buttons 24-32 are located on an associated add-on module. See CMD 980.

I tested again.
Key No.25 to 32 only support DSS key. Require CM 94 to activate, no need to assign F11XX to those keys.
To have 31 One-touch dial key, combine CM73 & CM90 to configure One-touch key of Key No.2 to 24.
