1. A new battery typically lasts one year with logging intervals greater than one minute Deployments in extremely cold or hot temperatures or logging intervals faster than one minute may significantly reduce battery life Continuous logging at the fastest logging rate of one second will deplete the battery in as little as two weeks Replacing the Battery You will need a small Philips head screwdriver and silicone based O ring grease such as Parker Super O Lube to complete these steps no petroleum based lubricants The logger should be wiped clean and dried completely before opening it To replace the battery 1 Avoid electrostatic discharge while handling the logger and internal circuit board ground yourself by touching an unpainted metal surface Hold the circuit board by its edges and avoid touching electronics 2 Working on a clean dry surface remove the two screws that secure the end cap to the case and remove the cap 3 Examine the desiccant pack that is tucked into the cap If the desiccant is not bright blue put the desiccant pack ina warm dry place until the blue color is restored Or for faster drying the desiccant can be dried for two hours ina 70 C 160 F oven 4 Gently tap the case to loosen the circuit board and remove it from the case Batter O88 O ring on end cap with Circuit board Logger case desiccant tucked inside BS 5 Carefully push the battery out of the holder with a small2. nonmetallic blunt instrument 6 Insert a new battery positive side facing up www onsetcomp com 7 Return the circuit board and label to the case carefully aligning the circuit board with the grooves in the case so that the battery faces the ridged side of the case 8 Remove the O ring from the end cap Use the thumb and finger of one hand to hold the cap from the top and bottom and use the thumb and fingers on your other hand to slide the O ring to form a loop as shown Use this loop to roll the O ring off the cap 9 Inspect the O ring for cracks or cuts and replace it if any are detected the O ring is included in the Pendant replacement parts kit UA PARTSKIT 10 Using your fingers not cloth or paper spread a small dot of silicone based grease on the O ring just enough to moisten it all the way around and making sure that the entire O ring surface is completely coated with grease As you work the grease into the O ring make sure there is no grit or debris on the O ring 11 Place the O ring back on the end cap making sure it is fully seated and level in the groove Make sure the O ring is not pinched or twisted and that no dirt lint hair or any debris is trapped on the O ring This is necessary to maintain a waterproof seal 12 Very slightly grease the inside rim of the case especially around the screw holes with the silicone grease just enough to moisten the inside edges without touching any circuitry M
