I have a BK 05 which is successfully paired with my android phone.  now i would also like to pair it with my ios device.  when i open it up, the power light is green for about 3 seconds, the state light is blue for about 1 second, then both lights go off.  When I go through the key sequences that are supposed to allow me to pair to a second device, the status light never tturns blue or flashing, it just stays unlit.  I have tried:

1.  choosing a different channel by pressing fn QWER

2. holding down the fn C key to enter pairing mode

3. pressing fn D for ios

I have also tried resetting the KB with Fn + Left Shift + Backspace.

I have tried both with my android device connected and disconnected and with BT on or off on the android device.

But none of these have worked.  The state light never flashes and none of my other devices, including my iOS devices can see the KB.

Any ideas?
