Many tone-only pagers have a silent memory mode in which pages can be received but no alert is given until the user presses a switch to interrogate the memory. The user gets no indication that anything has happened. Even in a lamp-equipped pager, a silent flashing alert (pager or low battery) may not be noticed before it times out. Some pagers use a vibrator to get the user's attention in silent mode, but this is not feasible in all products. One alternative is to give a short, low-volume beep when a page is received or low battery is detected. This feature can be implemented as a code plug option in a microcomputer- based pager through a simple software algorithm.
