Abstract
A tone only pager including an EEPROM with telephone numbers stored therein at different predetermined addresses and a DTMF signal generator. If a received signal includes one of the predetermined addresses, a DTMF telephone number corresponding to the address is generated. If a received signal also includes a different telephone number, any telephone number stored at that predetermined address may be replaced with the different telephone number. The pager also determines if the telephone number is a long distance telephone number and activates an indicator in response thereto.
