The batteres do not mantan the clock settng. If your clock s set manually and the IS9181
loses power, then the settng s lost. We recommend you have the clock set by the Internet (see
page 17), so when the power returns, the clock settng wll be automatcally set by the Internet.
The alarm clock does not work on battery power. The alarm clock must have AC power to work.
