PURPOSE:To quicken the adjustment and inspection by presetting an N value to receive a broadcast channel for tuner adjustment and check into a memory when the memory to which the value N of the frequency division ratio 1/N of a programmable counter is preset is initialized. CONSTITUTION:The titled tuner is provided with a 1st memory 18 to which the N value of the frequency division ratio 1/N of the programmable counter 3 is preset, a 2nd memory 17 storing the N value to select the reception frequency for the adjustment, measurement and check in advance, and a means writing the N value from the 2nd memory 17 to the 1st memory 18 when the 1st memory 18 is initialized. The N value for reception frequency selection such as adjustment is written automatically in the 1st memory 18. Thus, the adjustment is executed by using a channel selection button so as to select the N value stored in the 1st memory 18 and the tuning for each adjustment/ measurement is not required.
