TK-260G/(N)/270G/(N)
Since the TK-260G cannot be tuned from the panel, the FPU (KPG-56D) should be used for adjustment.
Adjust the receive BPF waveform according to the appropriate adjustment item.
Note
Precision parts are used for the PTT, side1, and side2 switches.
In order to avoid damaging these switches, do not press them using your fingers. However, if it is necessary to press these
switches, be sure to press them at 90˚ angles, pressing them at other angles can easily damage the parts.
