For the old MedEasy kit(blue), you can just open it directly and change inside situation.For the new MedEasy kit(black), you need to detach the fan wire from GPIO of Raspberry Pi 3, then open the box.

Check the wiring by Figure 1&2 first, then plug the fan wire to GPIO pin on Raspberry Pi 3

You may plug it wrongly, check again if you connect wire to the right pin. Or you connect the Vcc and ground

There may be 2 reasons, (1)if your smartphone still can receive WiFi from the kit, it means the LED wire may be haven’t connect to the Raspberry Pi 3 or connect wrongly, you can just fix it after you back to the headquarter, (2)if your smartphone cannot receive the WiFi from the kit, it means the Raspberry Pi 3 is not working->Q5

There may be few reasons,(1)the power bank is out of power, open the box and press the button on the power bank and check the led light on the power bank(1 LED light=around 25%,2 LED light=around 50%, 3 LED light=around 75%,4 LED light=around 99%)

(2) the wire connect to switch is loosed, just connect it again and can solve the problem
-
(3) the Raspberry Pi is overheat, open the box(Q1) and let it breath for few minutes
-
(4) sd card problem->Q6
-
(5) the raspberry pi is broken and you need to replace it with a new one

There are 2 LED light on the Raspberry Pi 3, one is red(PWR) which is power indicator, one is green(ACT) which show card status.(1 Flash: Make sure you are using the provided SD card, or another with a capacity larger than 4Gb; a 2Gb card won't work. 2 Flashes: The SD Card cannot be read.)
