HARGING THE
Charging the 276C Plus
Before using the unit, you may need to charge the battery in the
276C Plus. Simply plug the unit into an external power source to
charge. You can use the unit while it is charging.
To charge the unit's battery:
1. Lift the rubber weather cap to expose the power connector
on the back of the unit. Refer to the image on page 1 for
connector location.
2. Align the notches and push the plug into the connector until
fully seated.
3. Plug the 12 Volt adapter into an available AC outlet, or
cigarette lighter receptacle if you have a Cigarette Lighter
Adapter. Use care when routing the cable; be certain that it
does not interfere with vehicle operation.
The unit begins charging as soon as external power is applied.
Placing the unit in Charge mode, as discussed below, charges the
unit more quickly than when the unit is turned on and reduces draw
on the vessel/vehicle battery.
Information about Charge Mode
Applying external power to the 276C Plus automatically turns on
the unit for full operation. If the battery is present and needs to be
charged, the external power source charges the battery while the unit
is in use.

If you do not want to use the unit, but you would like to charge the
battery, you can put the unit into Charge mode. Connect the unit
to an external power supply. Press and hold the red POWER key.
Instead of completely turning off, the unit now goes into Charge
mode, as shown below.
Charge Mode
NOTE: While in Charge mode, the unit draws a small amount of
current from the vessel/vehicle battery. To avoid discharging the
vehicle's battery, disconnect the external power cable from the
276C Plus when not in use for several days.
After using the unit extensively, you may notice that the lithium-
ion battery is not holding a charge any more. This is common for
lithium-ion batteries. Contact Garmin or your Garmin Dealer to
order a Battery Pack replacement if you are experiencing charging
issues with your battery.
