Teardown and reassembly of BTN-1

Disassembly

You'll remove the lid, lift out the green PCB, and disconnect the battery.

If you have a BTN-1 with a battery you should flip the power switch to off

The BTN-1 ships with a lithium ion battery, however, this means it needs a master shutoff switch, which is on the left side of your BTN-1

1. Flip the battery switch towards you to the off position. Users with no battery skip to step 2.
