Connecting the Dongle to Radio
STEP ONE: Connecting to Two-Way Radio
To connect your Bluetooth dongle to a two-way radio, follow these steps:
* Always turn off your two-way radio before connecting the Bluetooth dongle.
* Plug the Bluetooth Dongle BT-Dongle into the speaker-microphone / audio
accessory jack of your two-way radio.
* On some models of two-way radio, you may need to tighten a retaining screw to
ensure that the Bluetooth dongle remains attached to the radio
* Turn on your two-way radio and verify that the radio transmits and receives with
the dongle attached.
* Because no wireless audio accessory will yet be paired to the Bluetooth dongle,
received signals should be heard over the radio’s internal speaker and transmitted
signals will be sent using the radio’s internal microphone.
* The Talk button on the Bluetooth dongle will not function as a Push-to-Talk
button for your two-way radio until a wireless audio accessory is successfully
paired to the dongle.
