104 Mesa Rugged Notepad Owner’s Manual
LED Indicators
Each baery compartment has a green and red LED. The LED
states indicate the following:
LED State Indicates
Red LED On Baery pack charging
Green LED On Baery pack fully charged
Red Flashing LED Baery pack or charging fault
Battery Pack or Charging Faults and Remedies
Possible causes for a ashing red LED:
Over-discharged baery: The baery pack is severely
depleted. The red LED ashes a few seconds aer the baery
is inserted. If the red LED continues to ash for a couple
of minutes, remove the baery pack. It might be faulty,
requiring replacement.
Pre-charge time out: A low baery pack is inserted and
the voltage does not reach an acceptable charge level. The
red LED ashes 30 minutes into the charge. The baery
pack might be at the end of its life or faulty, requiring
replacement. Note: Do not confuse this with the out-of-
temperature fault (next case).
Out-of-temperature range for safe charging: The charger
senses the baery pack is too cold (< 0˚ C, 32˚ F) or too hot
(> 40˚ C, 104˚ F) for safe charging. This can occur at any
time in the charge cycle. The red LED continues to ash,
even aer the baery pack is removed. Reset the charger by
inserting a baery pack with an acceptable temperature or
remove and reapply the external power to the charger. Bring
the temperature of the baery pack into the safe charging
range. If the problem persists, the baery pack might be
faulty, requiring replacement.
Charge cycle time out: The baery pack does not reach full
charge within eight hours. The baery pack might be at the
end of its life or faulty, requiring replacement.
