4.0 MAINTENANCE
This section explains which maintenance tasks can be
performed by the user. It also provides information regarding
replacement and optional parts. If you have any questions
concerning probe maintenance, consult ETS-Lindgren Customer
Service.
BATTERY REPLACEMENT
When the battery symbol lights to indicate low battery voltage,
replace both batteries. Batteries are replaced by removing the
two Phillips flat-head screws and the nuts and lockwashers (on
the two fiber optic connectors) on the bottom end plate of the HI-
3603 readout module. The batteries are held in place by the end
plate and will slide out easily when the plate is removed. Replace
with 9 volt alkaline (NEDA 1604A, Duracell MN1604 or equal)
being careful to observe proper polarity of each battery (refer to
the label on the bottom of the readout module case for proper
orientation of the batteries). When viewing the back side of the
HI-3603, the batteries go in with the positive terminal facing to
the left. The batteries are inserted with the battery terminals
pointed into the case as the batteries are inserted. As with any
battery operated device, do not leave exhausted batteries in the
instrument and remove batteries if the instrument will not be
used for an extended period of time.
