The values noted above are approximate values until power fails at normal tem- perature (25° C)(page 26). The above does not guarantee that you will be able to achieve this level of operation. Low temperatures shorten battery life. Voice re- cording times are based on continuous recording, while audio playback times are based on continuous output (through headphones).
