I am setting up a new SX-200ICP for a hotel, and for the life of me I can't figure out how to get the set wake-ups to set on a 5340/Sub phone... I programmed it per the documentation and put a Guest Room key on the phone, but when I press it and enter a room number, the only available prompts are Room No., DND, and O/G Rest but no Wake-Ups? I am sure I am missing something stupid, somebody care to point me in the right direction?
