Pairing with a PRYMEBLU Radio Adapter, 2-Way Radio, or Phone
The BTH-600-MAX speaker microphone is designed to work
with PRYMEBLU wireless adapters, and two-way radios with
internal BT made by BK, Icom, and Kenwood/EF Johnson,
as well as smartphone and tablets running either the
Android orApple iOS operating systems. Prior to normal
operation, the handset and speaker microphone must
be paired together using the following process:
• Hold down the Multifunction Button on the PRYMEBLU Speaker Microphone. Continue to hold the
button down for approximately 3 seconds, until you see the LED on the Speaker Microphone begin to
quickly flash RED-BLUE-RED-BLUE in sequence. The PRYMEBLU Speaker Microphone is now in pairing
mode.
• If you are pairing the microphone to a PRYMEBLU adapter, place the adapter into pairing mode
following the instructions in the user's manual for that device. Typically, this is done by holding down
the PTT button on the adapter while powering the adapter or attached two-way radio on and then
continuing to hold the PTT button down until the LED on the adapter flashes two times per second.
• If you are pairing the microphone with an Icom or Kenwood/EF Johnson two-way radio, follow the
manufacturer's instructions to have the radio scan for nearby headset devices. Once it finishes scanning,
select the PRYMEBLU microphone from the list of nearby devices.
* If you are pairing the microphone with a smartphone, make sure that the smartphone's BT slider is
turned on and then use the phone's BT menu to scan for nearby devices. Select the device named
"BTH-PTT" to pair with the phone.
• After a few seconds, the two devices should sync to one another. Once the PRYMEBLU Speaker
Microphone and Adapter, Radio, or Phone are paired with each other the status LED on the Speaker
Microphone will then show one FLASH every few seconds.
• Once successfully paired, you will be able to operate your 2-way radio using the PRYMEBLU Speaker Mic.
Reconnecting a Previously Paired Speaker Microphone and Two-Way Radio or Phone
Once the PRYMEBLU Speaker Microphone and adapter, radio or phone have been successfully paired
together, both devices will remember that connection. The adapter/radio and Speaker Mic will attempt
to re-establish their link whenever the adapter, radio or phone and Microphone handset are both
powered on and in within range of each other. Re-establishing this connection can take 10-60 seconds.
