and safety, having read this guide should attempt to
change the batteries.
Disconnect the instrument from all external power sources.
Remove the four (4) hex bolts from the sides of the
instrument housing (2 on each side).
NOTE:
Proper anti-static precautions should be used when
opening the instrument, such as a grounding strap.
Note the position and location of all ribbon cables.
Disconnect ribbon cables as necessary to securely rest the
instrument cover face down. Cut the tie-wraps holding the
batteries in and remove all of the old batteries. NOTE: All
three batteries should be replaced at the same time. Make
sure disposal of the used batteries is in accordance with
the local country regulations. Make sure the batteries are
first charged and fully discharged two or three times to
help extend battery life. Then finally fully charge the new
batteries before using the instrument.
