You can operate the autopilot with the status before the DODGE mode.
Note: In the AUTO mode, the [PORT] and [STBD] keys can be used to change
the course degree by 5°, 10° or 20° steps depending on the installation
setting. It is useful when you need to affect a large course change rapidly.
However, the DODGE mode becomes inoperative when this function is
activated. For details, ask your serviceman.
