1. Remove AC power adapter and USB cable.

2. Remove battery compartment cover and remove batteries.

3. There are ribbon cables by the battery compartment, at the heel of the gauge. With a small

screwdriver, ensure that back cable connectors are properly seated (note that there are two

ribbon cables back to back).

4. Re-connect the AC power adapter.

5. DM-2 will power on.

6. Press [Exit] to display the main operating screen.

Note that there are two physically separate connectors that need to be connected together. The one

in the rear can be quite difficult to physically connect, and care should be taken to ensure that both of

these connectors are firmly depressed.
