5.0 CHANGING THE BATTERIES

Batteries should be changed by service personnel.
» Use only brand name batteries.
» Replace with two AA batteries and insert per orientation marked on the device.
Should the batteries require changing, the device will indicate this in one of two ways:
» The battery icon on the bottom of the display will begin to flash. This icon will
continue to flash until the batteries are changed. The unit will continue to function
normally for approximately 200 hours.
» If the device detects a very low battery level, an error code of "E04" will be present on
the display, and the unit will not function until the batteries are changed.
To change the batteries, begin by removing the three screws from the back of
the device. A #1 Phillips screwdriver is required to remove these screws.
Once the screws are removed, gently separate the two halves of the device.
The batteries can now be replaced from
the back half of the case.
Be sure to orient the new batteries as
indicated in the embossed polarity on the
a back case.
NOTE: If the batteries are installed incorrectly the
batteries will not make contact and the device
will not operate.
Carefully, bring the two halves of the case together
while positioning the wires so they are not pinched
between the two case halves.
The gasket separating the halves will be captured
on the back case half. Reinsert the three screws
and tighten until the screws are snug. (FIGURE 3).
