There are two auto power off settings for the SimplFiber Pro source:
- Enabled, the source turns off after 30 minutes if no keys are pressed. (Default factory setting)
- Disabled, the source remains on until the battery dies. (40 Hrs for Multimode and 30 Hrs for Singlemode)
- If auto power-off is enabled, all LEDs turn on for 3 seconds.
- If auto power-off is disabled, all LEDs blink for 3 seconds and the LOW BATTERY LED blinks occasionally.
