  Wth this information, the user knows from the Backup Cell Status Update System display that the safe time to remove the primary cell is as shown in Figure A and Figure D. Removing the primary cell when the backup cell level is as shown in Figure B or Figure C will cause the Pager's RAM memory to

be erased. The Backup'Cell Status Update System display prevents the user from losing valuable infor- mation by informing the user that any information stored in the Pager's ram memory must be read before the primary cell can be removed.
