We all enjoy the sun and the heat to some extent and most golf is played in the summer. The Terminal can handle a lot of heat, but in some cases, it can be too much. There is no danger to the Terminal. It has a built-in thermal sensor that will detect if it is getting too hot. First, it will slow down to prevent too much heat generated from its internal power use, and eventually, it will stop all processes from running to protect it from damage.
If this happens, simply turn it off, let it cool down and it should be ready for use again.

To avoid too elevated temperatures, do not place the Terminal in direct sunlight in a non-cooled environment. It is not something we see very often, but it has happened.

An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context and ranges from 0 degrees Celsius/32 degrees Fahrenheit to 70 degrees Celsius/158 degrees Fahrenheit. Outside this range of safe operating temperatures, the device may fail.
