Problem Possible Cause Solution
My unit does not start. The battery is
completely discharged
(if the battery level
allows it, the unit’s LED
will blink quickly to
indicate the low battery
status).
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 with a new one
(see Replacing the Battery on
page 52).
My unit is not
responding.
The system has
encountered a problem.
Restart the unit.
The battery is not
recharging.
Ambient temperature is
too high or too low.
Make sure that the temperature in
the location where you recharge
the battery is within the
specifications.
The USB power adapter
is not connected
properly.
Make sure that the USB power
adapter is connected to the unit and
the AC outlet.
If the USB power adapter is
connected properly and the
problem persists, it could mean that
the USB power adapter is defective.
In this case, try replacing the
adapter. You can purchase new
USB power adapters from EXFO.
I have just replaced the
battery and the battery
gauge is not accurate
on-screen
The recharge cycle must
be reset for this new
battery.
Perform a full charge of the unit.
