The User determines which TGIDs’ messages are to be stored. All stored messages are time and date stamped and stored in non- volatile memory.  They can easily be retrieved by pressing the playback key button which plays stored messages on a last in/first out basis or by using the pager’s menu to selectively find the time and day the message was received. Message memory is very large and if it nears getting full it will automatically purge the oldest read/unread messages to make room for new incoming messages.
