This is exactly what I needed This was a hard one to find and I had already downloaded several for other Panasonic radios but none matched my radio.
Although my radio is the LBE model the LBS is the same.
A very good quality manual with every thing you should get in it
muy buen manual con multiples graficos y formas de onda ademas de muy completo y bien presentado.
