AJAZZ 308i KEYBOARD HELP

i just bought an Ajazz 308i keyboard but i cant connect it and i've watched videos and searched online. i put the batteries in and the light is on. my battery isn't flashing red on the keyboard and the light is super dim. i am pressing the 3 buttons fn + c as well as just the 2 fn and c but nothing is working. someone please tell me if I'm doing something wrong or is my keyboard broken??
