Batteries
The EM419 uses 8 AA cells for power. They can be Alkaline or NiMH/NiCad
rechargeable. The monitor will operate for ~14 hours on a fresh set of Alkaline cells,
and ~10 hours on fully charged NiMH/NiCad cells depending on the capacity.
To change the cells,
release the latches on
the either side of the
monitor and separate
the two halves where
you’ll find the batteries
readily accessible.
When closing the EM419
housing, perform a routine
inspection of the o-ring for
any foreign material or
damage. Replace if necessary
and clean the o-ring groove before
installing the new o-ring. Refer to the
Gates “Housing Care and Maintenance Guide”
for more information.
?
Caution
:
Verify the batteries are installed in the holder in the proper direction.
Reversed cells may leak acid and cause damage to the EM419.
?
Caution
:
Do not lubricate the large orange o-ring! It is a special silicone o-ring
and can be damaged by petroleum-based lubricants.
