Disconnect the old battery by gently pulling on the battery leads.

desiccant if not bright blue. To refresh desiccant,

at 100 C (210 F) for 20-30 minutes.

The logger must completely power down for a
clean restart. Wait at least 3 minutes between
disconnecting the old battery and reconnecting the
new battery for the on-board capacitors to
discharge.
9.
Connect the new battery by gently pushing the
polarized connector into the battery socket. Verify that the green and red LED’s flash three
times. If not, disconnect the battery, wait 3 minutes and repeat.
10.
Carefully slide the battery, circuit board holder, desiccant and circuit board back into the logger
housing. It may take a couple of attempts to get the hang of it. Do not use force. Gently push
the board all the way into the housing using the Circuit Board Holding Tool.

Use the hex driver to tighten the hex screws. Alternate sides and do not over torque. (Use four
fingers, not your whole arm!)
