Attention!

The FT-2500 uses non-volatile memory for parameter storage. The non-volatile memory has a limit on the number of write cycles, and the non-volatile memory used in this device is approximately 1 million cycles.
Under normal usage, it is unlikely to reach 1 million cycles, but if you frequently send numerical setting commands via RS-232C, it is expected to reach 1 million cycles. Please avoid this type of usage.
