Extender only has one button for both waking it up from sleep and recording. The table below outlines the behaviour.
Please note Extender will automatically sleep after 30 seconds if it is turned on but not connected with a headset or PC. Extender will automatically sleep if the battery is low and will blink the power LED before switching off.
