6.1.7. DISABLE RF POWER
Use this box to check when you do
not want to use the RF power
amplifier. It is commonly used for
dealers to make a demonstration of
the radio features without
interfering to any other existing
user in the frequency or for
operation without antenna
connected to the radio.
To disable the RF power amplifier,
check the box:
Press [OK] to store it in the file.
The value will be updated after the
file is transferred to the radio.
