PAIRING THE BTH-300-ZU WITH A SMARTPHONE
The BTH-300-ZU lapel microphone is designed to work with

systems. Prior to normal operation, the phone and lapel
microphone must be paired together using the following process:
1. When pairing the lapel microphone with a cellular phone, rst make sure that the BTH-300-ZU and
all other nearby Bluetooth devices are powered o before beginning.
2. Press and hold down the Power Button on the BTH-300-ZU for ve seconds, until the LED on the lapel
microphone ashes RED-BLUE-RED-BLUE continuously in sequence. The BTH-300-ZU lapel microphone is
now in pairing mode.

4. Activate the “scan/discover new Bluetooth devices” feature on the phone. The exact steps needed
to do this will vary depending on the brand/model of phone you are using.
5. Select the PRYMEBLU BTH-300-ZU from the list of Bluetooth devices shown on your phone. If the
phone asks for a passcode, enter “0000”. The phone may also prompt you to conrm the connection.
6. After a few seconds, the two devices should synch to one another. Once the PRYMEBLU lapel
microphone and phone are paired with each other, the status LED on the microphone will revert back
to a single blue ash every few seconds.

BTH-300-ZU lapel microphone.
Reconnecting a Previously Paired Lapel Microphone and Cellular Phone
Once the PRYMEBLU BTH-300-ZU lapel microphone and cellular telephone have been successfully paired
together, both devices will remember that connection. The lapel microphone and phone will attempt to
reestablish their link whenever they are both powered on and in within range of each other. Re-establishing this connection can take 10-60 seconds.
USING THE BTH-300-ZU LAPEL MICROPHONE
Once your PRYMEBLU BTH-300-ZU lapel microphone and cellular phone have been paired together:
Received calls and phone audio will be heard through the earphone that is plugged into your BTH-300-ZU
lapel microphone. The volume of received calls can be adjusted using the Volume Up and Volume Down
buttons on the lapel microphone or the volume control on the cellular phone.
As long as you are using a listen-only earphone, when transmitting or on a phone call, the operator’s voice
is picked-up by the microphone in the PRYMEBLU lapel microphone. If you are using a wired accessory
with a built-in microphone, the accessory microphone will be used instead.
