Commentary
A digital synthesizer tuner with quick tuning and memory speed per second.
It uses an auto-scan that stops automatically at the tuning point. If you press Down, it will select a lower frequency. If you press Up, it will select a higher frequency. In addition, since it is a turning scan method, it will return automatically even if it reaches the highest frequency with Up. (The same operation is performed when Down.)
In addition, manual operation is possible.
Memory of 6 AM/FM stations is available.
The FOMA terminal also has a built-in last One Call function that allows you to receive the station that you had received before turning off the power.
The FM section employs a 4-train front end, a 2-element ceramic filter, and a dedicated system IC group.
Equipped with a Rec level check function convenient for FM air check.
It is equipped with FL display reception frequency indicator and LED display 5-point signal meter.
