Philips dictionary pen

I have a Philips dictionary pen that does voice translation and text translation. It is capable of Bluetooth connection but I’m not able to connect it to my iPhone! It says it is Mac OS compatible. But my phone will search, hit pair but then it will stop and ask to forget device and try again. I’m sure my phone may be blocking it but how to I get my pen to connect to my iPhone?? Please help!
