New feature for units that can be powered or charged from USB (Recorder fm/v2, Ondios): USB power mode, based on patch #1110332 by Pieter Bos. This way you can save battery power or even charge the battery (fm/v2) while using your unit near a PC. Hold MODE (Ondio) or F1 (fm/v2) while plugging USB to enter that mode. A tiny USB plug icon will be displayed is the status bar (overridden by the regular power plug icon in case of fm/v2 when the charger is connected).
