What to do if my EXFO Measuring Instruments unit does not start?
- AAndrew ChavezAug 1, 2025
If your EXFO Measuring Instruments unit isn't starting, it could be due to several reasons. First, the battery might be completely discharged. If the battery level allows, the battery LED will remain red for about 5 seconds when you try to turn it on; in this case, connect the unit to an external power source to recharge the battery. If the battery is no longer charging properly, you may need to replace it. Alternatively, the system might have encountered a problem, or some essential files may be corrupted. For both of these issues, press the on/off button for at least ten seconds to force a hardware reset on the unit. If the problem persists after a hardware reset, try reverting the unit to its factory settings.
