Connecting the Adapter to Radio
STEP ONE: Connecting to a 2-way Radio
To connect your PRYMEBLU Adapter to a 2-way radio, follow these steps:
•
Always turn off your two-way radio before connecting the PRYMEBLU Adapter.
•
Plug the PRYMEBLU adapter into the speaker-microphone / audio accessory jack of your two-way radio.
•
Turn on your two-way radio and verify that the LED indicator on the PRYMEBLU Adapter flashes periodically.
If it does not, verify that the radio you are attempting to use the adapter with is a supported Kenwood model.
Some Kenwood radios do not supply power to the accessory connector. For these radios, you will need to use
the model PRYMEBLU BT-501 (which has its own internal battery pack) instead.
* NOTE: While the PRYMEBLU Adapter is attached to the radio and no Bluetooth headset is paired to the adapter,
the radio's internal speaker will be muted and you will be unable to hear incoming calls through the radio's speaker.
* NOTE: While the PRYMEBLU Adapter is attached to the radio and no Bluetooth headset is paired to the adapter,
you will be able to cause the radio to transmit by pressing either the PTT button on the side of the radio or the
Talk button on the PRYMEBLU Adapter. However, you will not have any transmit audio because the microphone
inside the radio is muted.
Pairing With an Audio Accessory
STEP TWO: Pairing with an Audio Accessory
• Turn off the radio that the PRYMEBLU Adapter is connected to. Wait at least three seconds.
• Turn the radio on while holding down the Talk button on the PRYMEBLU Adapter.
• Continue to hold the Talk button down for approximately three seconds. Release the Talk button
when the status LED begins to ash two times per second.
• The PRYMEBLU Adapter is now in audio accessory pairing mode. Activate the pairing mode on your
compatible wireless audio accessory.
• Once the wireless audio accessory and PRYMEBLU Adapter are paired with each other, the status LED
on the adapter will show a constant blue light for three seconds.
• If the PRYMEBLU Adapter does not detect a compatible wireless accessory within 60 seconds of being
put into pairing mode, the adapter will exit the pairing mode and resume normal operation.
• Once successfully paired, you will be able to operate your two-way radio using your compatible
wireless accessory.
Reconnecting to a Previously Paired Headset
Once the PRYMEBLU Adapter has been successfully paired to a Bluetooth headset it will remember that
connection. If the headset is powered off or loses connection, the adapter will attempt to reestablish the
connection. The adapter and headset will attempt to reestablish their link whenever when the radio/adapter
and headset are both turned on and in within range of each other. Re-establishing this connection can take
10-60 seconds.
