Setting Auto Release
Choose this option to set the Function Auto Release to On or Off.
Turning the Auto-Release on lets you press any key to exit the Function mode.
Turning the Auto-Release off (the default setting) means you can only press the Function key to exit Function mode. No other key has any effect.

Volume Settings - For Handy Scanner
While it is possible to configure the UBC-RH96 rotary FUNC control as your VOL control, we suggest not doing so. The VOL control still functions as a volume control. If the FUNC control is configured as volume, it is possible to have a situation that a very slight movement of the VOL control results in a sudden and loud increase in your audio. It is best to configure the VOL control as volume in all cases.
