• call reminding means for resuming said informing operation at a predetermined interval after a second period of time has elapsed from a beginning of said informing operation, said second period of time being longer than said first period of time;
• and
• controlling means for increasing said predetermined interval in proportion to number of times said informing operation by said call reminding means is preformed.

• a detector for detecting an address of said pager in a received signal;
• informing means for performing at least one informing operation for a predetermined time period for informing a user of an incoming call;
• and
• a controller, coupled to said informing means, for controlling an interval between sequential informing operations, said interval being increased in accordance with a number of said informing operations performed by said informing means.

A method for controlling a call informing operation of a call informing device, said method comprising the steps of:

• informing a user of an incoming call for a first predetermined period of time when an address included in a received signal corresponds to a pre-assigned call number of said call informing device;
• reminding the user of said incoming call by performing an informing operation for said first predetermined period of time when a second time period has elapsed after said first period of time and repeating said informing operation at said second time period interval;
• and
• increasing a duration of said second time period interval in accordance with a number of times said informing operation is performed.

A method for controlling a call informing operation of a call informing device, said method comprising the steps of:

• performing at least one informing operation for a predetermined period of time to inform a user of an incoming call;
• determining a number of informing operations performed;
• and
• controlling an interruption interval between sequential informing operations, wherein said interruption interval is increased in said controlling step in accordance with said number of said informing operations determined in said determining step.
