Set the correct Device on your gauge because it will calculate different results depending on which

Device is selected.

9.10 Keep the Keep Rechargeable Batteries in top shape

The DM-2 is designed to recharge NiMH batteries in the gauge, eliminating the need to purchase a

stand-alone battery charger. The charging cycle is designed to fully discharge batteries before

recharging them. This can cause problems if the DM-2 is connected to a power plug for only brief

periods of time.

If the gauge exhibits any of the following conditions, it may be a problem with the rechargeable

batteries:

 Short battery life

 Will not turn on

 Keys will not respond

 Loss of power during test

The solution is to reset gauge and charge the batteries, or switch to non-

rechargeable batteries (remember to change the setting to tell the gauge

about the switch in battery type using [Settings] to set the “Battery Type”.

To charge the batteries:

1. Connect the AC power supply if rechargeable NiMH batteries are already installed.
