To install batteries for the first time

1. Using a small Phillips screwdriver, open the lower back

panel of the DM-2.

2. Install the four AA rechargeable NiMH batteries,

making sure to align them correctly, and ensuring that

the contacts are secure against both the positive and

negative ends of each battery.

3. Replace the battery compartment panel and securely

tighten the screw.

4. Plug the AC power adapter into a wall outlet and into

the DM-2 DC power receptacle.

5. Turn the gauge on.

6. Allow the batteries to charge until the charging is

complete (according to the battery status indicator).

This may take up to 24 hours.

Caution: Do not open the panel labeled “No User Serviceable Parts Inside. Do Not Open.” Doing so will

void the calibration and warranty.

Rechargeable or non-rechargeable (alkaline) batteries

The standard NiMH batteries that are included with the DM-2 should last for two years of constant

use. Every six months, it is worthwhile to remove the batteries and place them in a quality charger.

This reconditions them and extends their life. Non-rechargeable batteries can also be used, but the

charging circuit should be disabled to prevent accidental charging. Charging an alkaline battery may

cause it to explode or leak.

To replace the current batteries

1. Using a small Phillips screwdriver, open the lower back panel of the DM-2.

2. Remove the four old AA batteries and recycle them at a participating collection center.

3. Install four new AA batteries, making sure to align them correctly, and ensuring that the

contacts are secure against both the positive and negative ends of each battery. The DM-2

can use either rechargeable NiMH batteries, or standard alkaline batteries.

4. Replace the battery compartment panel and securely tighten the screw.

If a different type of battery is used (i.e. change from rechargeable to non-rechargeable), make sure to

change the battery type in the Setup Menu of the DM-2. When "Not Rechargeable" is selected, the

batteries, regardless of type, will not be charged. Attempting to charge non-rechargeable batteries can

cause the batteries to leak, permanently damaging the DM-2.

To select proper battery type

1. Press [Setup].

2. Scroll to "Battery Type" and select "Rechargeable" or "Not Rechargeable" as needed.

3. Press [Exit].
