Charging The Gpsmap 276C; Information About The Charge Mode - Garmin GPSMAP 276C Owner's Manual

Charging the GPSMAP 276C

Before using the unit, you may fi nd that you need to charge the unit. Simply plug the unit into an
external power source to charge. You can use the unit while it is charging.
To charge the unit:
1. Lift the 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 adapter cable being certain that it does not
interfere with vehicle operation.
4. The unit begins charging as soon as external power is applied. You can use the unit while it is
charging. 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 vehicle/boat battery.

Information about the Charge Mode

Applying external power to the GPSMAP 276C automatically starts the unit for full operation. If the
battery is present and needs to be charged, the external power source charges the unit while it 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
the 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 the "Charge Mode" as shown to the right.
NOTE: While in Charge Mode, the unit does draw a small amount of current from the vehicle/
boat battery. To avoid discharging the vehicle's battery, disconnect the external power cable
from the GPSMAP 276C unit when not in use for several days.
After much use, the lithium-ion battery in the unit may seem like it is not holding a charge any
longer. This is common for lithium-ion batteries. Please contact Garmin or your Garmin Dealer to order
a Battery Pack replacement if you are experiencing charging issues.
