Four power levels are available on the FT-817ND: 5 Watts, 2.5 Watts, 1 Watt, and
0.5 Watt. When using Alkaline batteries or the supplied FNB-85 Ni-MH Battery
Pack, the microprocessor, detecting internal battery use, automatically sets the power
level to 2.5 Watts, which appears on the display as “**”. If you set the power to five
watts, the power level icon is the same as for 2.5 Watt operation, but at 5 Watts the
icon is blinking. For 0.5 Watt, there is one “bar” to the right of the “L” in the power
icon, and for 1 Watt there are two “bars” displayed.
