CHARGING THE HEADSET
The PRYMEBLU Muff Headset has an internal Lithium Ion rechargeable battery pack which must be
charged prior to operation. A fully charged battery will provide approximately 10 hours (or more) of
operation before needing to be recharged. However, operating time can vary depending on usage and
the condition of the battery pack. Recharge the battery regularly.
To charge the PRYMEBLU Headset:
1. Ensure the PRYMEBLU Headset is turned off using the Power Button.
2. Plug the supplied wall charger into a standard 120 volt AC outlet.
3. Plug the charge cable into the AC wall charger and then into the charge jack on the Headset. You
will need to remove the protective rubber cover that is inserted into the charge jack. (To prevent dust
and moisture from damaging your Headset, always ensure this cover is in place when you are not
charging the Headset.)
4. Once the charging process has begun, the LED indicator on the Headset will show a continuous red
light. When the battery is done charging, the LED light will turn off.
5. Typical charge time is approximately 4 hours. Actual charge time will vary depending on several
factors including the battery's charge state, condition, and age.
6. Disconnect the charger from the lapel mic when charging is completed.
Charging Cautions:
- Use only the wall charger supplied by the
manufacturer. Do not use any other charger.
- Do not use a wall charger that appears
to be damaged. (Example: frayed wires,
melted plastic, etc.) Contact PRYME to
get a new manufacturer-approved
replacement charger.
- Do not tamper with or modify the
Headset or charger.
- Always turn the power switch to the off position
when charging the Headset.

PAIRING THE HEADSET WITH A PRYMEBLU ADAPTER OR CELLULAR TELEPHONE
Before you can use the PRYMEBLU Muff Headset,
it must be paired with the PRYMEBLU BT
adapter and/or cellular telephone that you wish
to use.
To pair the Headset with a PRYMEBLU BT radio adapter:
1. Begin by first making sure that the Headset, PRYMEBLU radio adapter, and the two-way radio the
adapter is connected to are all powered off. You should also power off any nearby BT devices.
2. Place the PRYMEBLU radio adapter into pairing mode by following the instructions that were provided
with that device. On most PRYMEBLU adapters this is done by pressing and holding the PTT/Multifunction
button on the adapter while turning the two-way radio on. Continue to hold the button down until the LED
indicator on the adapter shows two blue flashes every second.
3. Press and hold down the Power Button on the PRYMEBLU Muff Headset for five seconds, until the LED on
the Headset flashes RED-BLUE-RED-BLUE continuously in sequence. The Headset is now in pairing mode.
4. After a few seconds, the two devices should synch to one another. Once the Headset and PRYMEBLU radio
adapter are paired with each other the status LED on the adapter will show a constant blue light for three
seconds. The LEDs on both the adapter and Headset will then show one blue flash every few seconds.
5. If the PRYMEBLU radio adapter does not detect the Headset within 60 seconds of being put into pairing mode,
the adapter will exit the pairing mode and resume normal operation without synching to the .
6. Once successfully paired, you will be able to operate your 2-way radio using the PRYMEBLU Muff Headset.
To pair the Muff Headset with a cellular telephone:
The PRYMEBLU headset is capable of working with a BT-enabled cellular telephone.
1. When pairing the Headset with a cellular phone, first make sure that the headset and all other nearby BT
devices are powered off before beginning.
2. Press and hold down the Power Button on the headset for five seconds, until the LED on the adapter flashes
RED-BLUE-RED-BLUE continuously in sequence. The headset Headset is now in pairing mode.
3. Activate the BT feature on your phone.
4. Activate the "scan/discover new BT 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 Headset from the list of BT devices shown on your phone. If the phone asks for a passcode,
enter "0000". The phone may also prompt you to confirm the connection.
6. After a few seconds, the two devices should synch to one another. Once the PRYMEBLU Headset and
phone are paired with each other, the status LED on the microphone will revert back to a single blue flash
every few seconds.
7. Once successfully paired, you will be able to make and receive telephone calls using the Headset.
