Hello. Our office is having a phone issue. The receptionist's phone Exectone 84600-40 was programmed to a Exectone Model DSS48. Appears the DSS48 stopped functioning over the weekend when the system was in Night mode. Not sure how to get the system off night mode. Any help is appreciated. We no longer need the DSS48 but need to get the system off night mode.

Thanks for any help.
