7.11 The keys on the DM-2 Keypad are not working

If the DM-2 will power on, but one or more keys do not work, the cables may have come dislodged. To

rectify the cable problem, follow these steps:

To reconnect the keypad cable

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 heal 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.
