Maximum Temperature: Under extreme environmental and operating conditions, specific maximum surface temperatures are listed below. Each of these specific surfaces also lists an expected user contact limit as follows:
The Key panel can reach up to 140°F (60°C). This surface is intended to be touched for less than one minute at a time. The clear plastic window on the carrying case can reach up to 118.4°F (48°C). This surface is intended to be touched for less than ten minutes at a time. The remainder of the carrying case can reach up to 109.4°F (43°C). This surface has no time limitation on user contact.
