ABSTRACT:
A paging apparatus having a message display function in which one or more of the messages stored in a message memory may be erased in response to the operation of a test switch in the factory during manufacturing. The paging apparatus is of a type that does not include a power switch. Rather, power is supplied immediately upon connection of a battery. Accordingly, a test switch which is inaccessible to the normal user is provided to switch the operation of the paging apparatus from a normal mode to a test mode or vice versa.
