When the inReach SE or inReach Explorer begins to overheat while charging the device will display an "!" icon near the battery indicator. This is caused by several possible factors:

• Leaving the inReach by a window on a sunny day
• Leaving the device near a heating element
• Leaving the device on a dashboard without the use of a mount
• Resting the inReach on other warm electronics

To resolve this issue remove the inReach from the charger and let it sit in a room temperature area for a few minutes so it can cool down.
