5360 screensaver option disabled

[ucx]

A customer has a couple of 5360 phones and wishes to disable the screensaver on them. In the Settings menu, we can change the timeout for the screensaver to activate, but the 'Display Image' option is ticked but greyed out. This is how they came out of the box.
Is there any way to a) enable this option so we can de-select it; or b) disable the screensaver entirely?

Thanks.

Disabling the sceensaver in NOT possible. The menu option is there as the first firmware version did support this. Mitel has taken this out to protect the display of the phone. If the customer doesn't like the screensaver then advise them to change into something they like.

Fair enough, I thought it might be something like that. Thanks for the reply.

Could you not delete the default screensaver.spx file from the 3300?
