Commentary
FM/AM program timer tuner with integrated program timer.
The tuner section is equipped with a preset mechanism that can store eight FM/AM stations at random. In addition, each station can store settings such as muting and FM mode, so that the desired station can be selected by one touch with the best reception condition.
We also use non-volatile memory ICs that do not require a backup power supply.
Equipped with a last station memory function that stores the station that was received just before the power is turned off or band switching.
The timer section can be set to ON/OFF three times a day for a total of 21 times in a week with an accuracy of ± 15 seconds per month. In addition, you can choose the day of the week you want to reserve.
In addition, it is equipped with a station program mechanism for up to three stations that call up the specified preset stations one after another in conjunction with ON/OFF commands.
In addition, it is equipped with 2 series timer linked outlet.
Equipped with a wake-up function that switches the volume between two levels in conjunction with the brightness of the timer display.
As a result, even if you use it as a sleep timer at a low volume at night, it will automatically return to its original volume in the next morning and become an alarm clock.
