Q: How do I connect my LG bluetooth device to my Mac Pro-retina display?

from the LG manual:

Pairing

- Before using the headset for the first time, you must pair it with a Bluetooth-enabled

device.

- There are 2 pairing mode methods with the HBS-750.

 

1) Easy Pairing

a) Slide the power switch to the "ON" position.

b) If it is your first time pairing the device it will automatically enter pairing mode.

If it has been paired but no paired device is in range it will enter pairing mode

after 10 seconds.

• The LED indicator will be solid blue.

c) On the device you wish to pair, find the Bluetooth menu and "search for" or

"add" new devices.

d) Select "LG HBS750" from the list of devices.

e) If asked for a Pass/Pin Code enter 0000 (4 Zeros).

f) Once the devices are paired, you will hear "Your headset paired.".

• The HBS-750 will automatically turn off if not paired within 3 minutes.

 

2) Manual Pairing (pairing with another phone or re-pairing)

a) With the power off, press the CALL button and slide the power switch to the

'ON' position at the same time for 2 seconds.

b) When the headset enters Pairing Mode, the LED indicator will show a solid

blue light. After the procedure repeat Easy Pairing steps "c)" through "f)".
