BATTERY REPLACEMENTThe Minnow 2.0 logger runs from two standard coin cellbatteries. We recommend a CR2032 240mAH coin cellbattery. There are different manufacturers but a good
one is Panasonic CR-2032. You can find it easily on theweb from different places such as www.digikey.com,www2.mouser.com and probably in your local
supermarket. The key thing is to choose a CR2450
battery with high capacity since this will translate into alonger logger battery life.

6.

Figure 13: Language PreferenceFirst remove the Minnow cover by unscrewing the four
fastener screws (#1 Philips) at the rear of the logger.
Insert two new batteries as shown being careful not totouch any exposed electronics in the process. Be carefulalso to connect the batteries in the correct orientation.
Finally re-attach the cover and tighten the fastenerscrews again (be careful not to over tighten).
