Communication apparatus, memory medium and method

A memory medium that stores machine readable instructions for controlling a communication apparatus having a transmitter-receiver and a display, the memory medium comprising:

• instructions for gradually changing at least one of an input level of the transmitter-receiver and an output level of the transmitter-receiver to assist in detecting a caller identity of a second external apparatus, if an interrupt signal is received from the second external apparatus during a communication with a first external apparatus.

A method of controlling a communication device having a transmitter-receiver and a display, comprising:

• receiving an interrupt signal from a second external apparatus while the communication device is communicating with a first external apparatus;
• and
• gradually changing at least one of an input level of the transmitter-receiver and an output level of the transmitter-receiver to assist in detecting a caller identity of the second external apparatus, in response to receiving the interrupt signal.

A communication apparatus, comprising:

• a transmitter-receiver;
• and
• an input/output level control device that initially increases at least one of an input level of the transmitter-receiver and an output level of the transmitter-receiver concerning a communication with a first external apparatus, if an interrupt signal is received from a second external apparatus during the communication with the first external apparatus to assist in detecting a caller identity of the second external apparatus.
