Multipoint GPS Pairing
If you use GPS only for turn-by-turn voice instructions, not for Bluetooth
stereo music streaming, multipoint pairing is recommended for the GPS
connection. Multipoint Bluetooth pairing allows the SMH3 to connect two
HFP devices at the same time: mobile phone and GPS navigation. Follow
the steps below to pair the GPS using the multipoint pairing.
1. Turn on the headset and press and hold the (-) Button for 5 seconds
until the red LED is rapidly flashing and you hear multiple beeps.
2. Within 2 seconds, press and hold the (+) Button for 1 second, then
the LED turns to blue flashing and the beeps turn to high tone double
beeps. You will hear a voice prompt saying "Multipoint pairing".
3. Search for Bluetooth devices on the GPS navigation screen. Select
the Sena SMH3 in the list of the devices detected on the GPS.
4. Enter 0000 for the PIN.
5. The GPS confirms that pairing has completed and the SMH3 is ready
to use. You will hear a voice prompt from the SMH3 saying "Your
headset is paired".
6. If the pairing process is not completed within three minutes, the
SMH3 will return to stand-by mode.
The pairing diagram for multipoint GPS pairing is shown in the figure
