CHARGING THE HEADSET
The headset contains an internal lithium-ion rechargeable battery pack that must be charged before first
use and recharged regularly. A fully charged battery can provide up to 8 hours of continuous operation
before needing to be recharged. However, actual operating time may vary based on usage and the
condition of the battery. Recharge the battery regularly.
To Charge the Headset:
1. Ensure the device is powered off.
2. Connect the charging cable to any powered USB outlet, such as an AC wall charger, and plug the other
end into the charging port on the headset.
3. Once charging begins, the LED indicator on the headset will display a constant red light.
4. Typical charging time is approximately 2 hours, though it may vary depending on factors such as the
battery's current charge level, condition, and age.
5. When the battery is fully charged, the LED indicator will change to a constant blue light.
6. Disconnect the charger from the headset once charging is complete.
Charging Cautions:
- Ensure the charging port is free of water or debris before connecting the charger.
- Do not use a wall charger or charging cable that appears damaged (e.g., frayed wires, melted plastic,
etc.). Contact PRYME to obtain a manufacturer-approved replacement.
- Do not tamper with or modify the headset or charger.
- Make sure the rubber cover is securely in place over the charging port when not in use.
- Always turn the headset off while charging.
WEARING THE HEADSET
Wear the headset as shown in the image.
Position the ear hooks over your ears, ensuring
that the boom mic rests comfortably in front of
your mouth. The bone conduction transducers
should be placed directly in front of your ear,
flat against your skull, just below your temples.

PAIRING THE HEADSET
The headset can be paired with a PRYMEBLU
radio adapter, a two-way radio with built-in
BT functionality, a smartphone or tablet
running Android or iOS, or a Windows PC.
Before using the headset, it must be paired with your chosen device by following these steps:
• Power on the headset.
• After powering on, the headset will automatically enter pairing mode, and the LED will quickly flash in a
RED-BLUE-RED-BLUE sequence.
• If pairing with a PRYMEBLU adapter, put the adapter into pairing mode by following the instructions in the user manual.
• If pairing with a two-way radio, follow the radio manufacturer's instructions to scan for nearby BT devices.
Once scanning is complete, select the headset from the list.
• If pairing with a smartphone or tablet, ensure the device's BT is turned on, then access the BT menu and scan for
nearby devices. Select the headset from the list.
• If pairing with a Windows PC, go to "Start > BT & Devices > Devices" and then click "Add Device > BT" and select
the headset from the list of nearby devices.
• After a few seconds, the two devices should sync. Once paired, the headset's status LED will flash blue once every
ten seconds.
Reconnecting a Previously Paired Device
Once the headset has been successfully paired, both devices will remember the connection. They will attempt to
re-establish their link whenever they are both powered on and within range. This reconnection process may take
between 10 to 60 seconds.
MULTI-PAIRING
The headset can be connected to two devices simultaneously. To connect a second device, such as a phone
or tablet, in addition to a PRYMEBLU adapter, follow these steps:
1. Power off or disable BT on the first connected device.
2. Repeat the pairing process with the second device as described earlier.
3. Once the second device is paired and connected, simply power on or re-enable BT on the first device.
PRYMEBLU adapters and two-way radios may block some functions on the second device, such as
streaming audio and music.
POWER/VOLUME+ BUTTON
This button is used to power the headset
on and off, adjust the volume up, or advance
to the next song when listening to music.
VOLUME- BUTTON
This button is used to decrease the
volume or go back to the previous song.
CHARGE PORT
This USB-C port is used for recharging the
headset by connecting the BTH-M100V to
a USB charger or any USB power source.
BONE CONDUCTION TRANSDUCERS
These speakers transmit audio through
vibrations, allowing the user to hear both
the headset audio and ambient sounds
by keeping the ears open and uncovered.
NOISE REDUCTION BOOM MICROPHONE
Dual microphones are used to cancel out
surrounding background noise while
transmitting clear voice audio.
