Handset 500 - Desactivate OK button to active alarme

[jpissot]

Hi,

I have configured an alarm og the dect 500.

When I "long" pressed the SOS button, the mobile calls an extension.

When I "long" pressed the OK button; the mobile calls also.

How can I desactivate the SOS function of the OK button?

Thanks for your help.

My mobile 500 is with release v35-8. I 've upgraded it with release v54.

Now, I can desactivate the OK button to active SOS.
On "Alarm Status" menu, i can validate Key Events or not.

Bye
