Solving Common Problems
The battery is not
recharging.
Ambient temperature is
too high or too low.
In this case, the unit’s LED is blue
and blinks slowly.
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.
In this case, the unit’s LED is not
blinking at all, but there is a battery
icon with a flash symbol displayed
on screen.
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 unit’s
LED turns to red when I
turn on the unit.
The unit may take a little
time to detect the level
of a new battery.
Connect the unit to a power outlet
with the provided USB power
adapter and let the battery charge
for a few minutes. After a short
while, the unit should turn on.
However, it could take a few
charge/discharge cycles before the
unit’s LED indicator and the
on-screen battery status icon reflect
the actual power level of the new
battery.
