IMPORTANT! (for 65 W transmission):
The IC-2300H has a built-in current detector circuit
which protects the power amplifier from excessive cur-
rent flow. When excessive current flow is detected, the
circuit automatically reduces the transmit output power
to approximately 25 watts.
The IC-2300H has a thermal detector circuit too, which
protects the power amplifier from excessive heat. As
the temperature increases, the circuit automatically re-
duces the transmit output power to approximately 10 to
20 watts.
