Using The Apo Function - Yaesu FTM-400DR Operating Manual

Using the APO function
When the APO (Automatic Power-off) function is set to ON, the power supply to the
radio will be automatically switched off when there has been no operation for a preset
period of time. A notification beep will sound one minute before the power is turned off.
This helps to prevent the battery from being used up when you forget to switch the radio
off when connected to a car battery.
