PHONE

摘要

PROBLEM TO BE SOLVED: To provide a phone that can inform a user as to whether or not an incoming call comes from a desired opposite party depending on the number of the ringer tones. SOLUTION: When a caller number detection section 210 detects a caller telephone number at the arrival of an incoming call, the phone allows a speaker 150 to output a ringer tone by 1st number of times (e.g. 6 times) and when the caller number detection section 210 detects no caller telephone number at the arrival of the incoming call, the phone allows the speaker 150 to output a ringer tone by 2nd number of times (e.g. 2 times).
