Charging the Gauge
The gauge is equipped with a rechargeable nickel-metal hydride
(NiMH) battery pack containing five C batteries. Before turning
on the gauge, charge the battery for about 3 hours.
To charge the NiMH batteries:
1. Plug the AC charger or DC adapter into the charger
connector under the gauge’s Port Cover (see Figure 3 on
page 3–3). The battery charge indictor icon ( ) appears on
the top-right of the display.
If using the AC charger, plug the other end of the charger
into a standard 100–240 V AC outlet.
If using the DC adapter, connect the other end to any 12-14
V DC source (such as a vehicle's power receptacle).
2. After the gauge is fully charged (approximately 3 hours),
unplug the AC charger or DC adapter and store for later use.
