4.8 Bluetooth Pairing with Mobile Devices
1. When you power up the CS108 reader, the Bluetooth LED will automatically flash blue,
meaning it is now discoverable by smart devices nearby. NOTE: the CS108 uses only the
Bluetooth Low Energy protocol, therefore smart devices must have Bluetooth 4.0/4.1/4.2 to
be able to connect to the CS108.
2. With the Bluetooth LED flashing, you can search, discover and connect the CS108 to the
CSL Demo App or customer written app. NOTE that you can only connect to the CS108
via the CSL Demo App or customer written application. You cannot connect the CS108
Bluetooth via the standard Bluetooth pairing function of the OS of the smart device.
4.9 Charging the CS108
4.9.1 Direct Charging CS108
The CS108 can be directly charged by inserting a USB cable with the following plugs:
1) USB Type C plug on one side
2) USB Type A plug on the other side
3) The above Type A plug connecting to a USB charger with the traditional Type A socket.
The charger can be 1A or 2A.
2 LEDs will light up:
1) “Ext. Power” LED: Green LED. Whenever the CS108 is connected to an external power
supply, this Green LED will light up.
2) “Charging” LED: Red LED. When the battery is heavily drained, this red LED will be
bright. When the battery is completely recharged, this red LED will be very dim. Do not be
alarmed if you connect the USB cable and this LED is very dim. It just means the battery is
fully charged
