1.HOW TO FIND A BLANK FREQUENCY:
Please find the “EMPTY” frequency of the car radio (87.5-108.0 MHz) which produces a slight regular noise if the frequency is not occupied.
Tip: “EMPTY” means a station without music or voice, only with background noise.
2.HOW TO AJUST FM FREQUENCY:
Long press the “MFB” button, when frequency is flashing; push up/right “MFB”button to increase frequency; push down/left “MFB” button to decrease frequency.
3.HOW TO PAIR FREQUENCY:
Find the “EMPTY” frequency on the car radio and set the FM transmitter to the same frequency. After synchronization, the sound will be very quiet (if static, please try the new “EMPTY” frequency on the car radio).
4.HOW TO ADJUST VOLUME:
Push the “MFB” button up to increase the volume and down to decrease it. When the volume is at maximum, a drip tone will sound.
5.IF YOU CAN’T CONNECT THE BLUETOOTH, TRY THESE STEPS:
Delete the Bluetooth pairing history stored on your phone, deactivate Bluetooth and unplug the transmitter. Reconnect it to the cigarette lighter socket, turn on Bluetooth and try to reconnect.
