Symptom
Possible cause
Possible solution
No power
Not powered up
Turn on the ON/OFF switch, located on the right side of the unit.
Verify the internal battery life indicator on the left side of the unit.
Battery empty
Verify the internal battery life indicator on the left side of the unit.
Connect the EasyTest II power supply to the EasyTest II for at least 3h.
Battery not recharging
When connected to charge, the most significant segment of the
battery life indicator will blink. Try another main outlet for the
power supply.
Power supply
Verify the power supply connection. If possible, try another power
supply (with the same power requirements). If the power supply is
faulty, call FISO to get a replacement.
Bad diagnostic values
Dirty connectors
Clean the connectors using the EasyClean (if they are oily, use optic
wipe and 99% Isopropyl alcohol)
Sharp bend along the fiber
Correct the installation, respecting the long term minimum bending
radius of 17mm
Sensor Pitted connector
Replace the sensor
CFO-ET worn-out
Validate your CFO-ET, by connecting the EasyCheck to the Port Saver
optical connector, if the Light is higher than 10% or the signal lower
than 90% you should probably change your CFO-ET.
