The Two-Door Monitor has a pocket-sized receiver. It will receive and
store alert signals from up to 2 zones. Each zone can store up to 400
events with a date/time stamp. In addition, each zone can store up to
999 events without the date/time stamp. With the counter function you
will know when the monitor was activated.
The rechargable Li-Ion
battery will hold a charge for up to 10 days. In addition to the LCD
display, the pager will also give an audible tone for each of the two zones and a vibrate alert for times when you need it to be silent.
