Some paging devices can receive pages (or messages) after they are turned off. These devices vibrate to notify the user when they receive a page and do not produce an audible alarm.
The Newton Messaging Card cannot receive pages when it is turned off, and does not support vibrating notification. Its audible alarm can not be disabled while the unit is on.
The Messaging Card must be on to receive a page, but it does not need to be inserted into the Newton. To review pages that may have been sent to you while the Messaging Card was turned off, call the toll-free number in your Apple Wireless Messaging Service quick reference guide.
