CHARGING THE HEADSET
The PRYMEMAX 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.
PUSH-TO-TALK BUTTON
Pressing and holding this button
down activates the Push-to-Talk
feature of the two-way radio or
PoC app.
The PTT button on the
BTH-900-MAX is different than the
BTH-700-MAX and BTH-800-MAX.
PHONE BUTTON
If the Headset is paired with a cellular
telephone, this button can be used to
manage telephone functions such as
answering or hanging up a call.
USB CHARGE JACK
This micro-USB jack is used to connect
the supplied charge cable to the Headset
to recharge the device’s internal
lithium-ion battery pack.
MUFF EARPHONES
Received calls are heard through
these Headset speakers.
HEADBAND / HELMET MOUNTING CLIPS
Depending on the model, the headset may
be furnished with mounting clips for
attaching to a hard hat
(SPM-700-HMx-MAX), an over-the-head
band (SPM-800-OHx-MAX) or a
behind-the-head band
(SPM-900-EMx-MAX).
VOLUME UP/DOWN BUTTONS
These buttons are used to adjust
the volume level of received calls
heard through the Headset.
POWER BUTTON / STATUS LED
Pressing and holding this button for
one second turns the PRYMEMAX
Muff Headset on or off. This button
is also used to place the Headset in
pairing mode so that it can be
connected wirelessly to a
PRYMEBLU adapter, two-way radio,
or a cellular telephone. The status
LED behind the button flashes
messages that let the user know the
status of the device. For a complete
list of LED messages, see page 6.
To charge the PRYMEMAX 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.
P-CBL-USB-MICRO charger cable and P-CHA-BT-USB
wall charger included with the Headset.
PAIRING WITH A SMARTPHONE OR TWO-WAY RADIO
The PRYMEMAX headset is designed to work with PRYMEBLU wireless adapters, two-way radios with
internal BT made by BK, Icom, and Kenwood as well as smartphone and tablets running either the Android
or Apple iOS operating systems. Prior to normal operation, the handset and headset must be paired
together using the following process:
1. With the headset powered off, activate the pairing mode by pressing and holding the Power button
until the status LED flashes BLUE-RED-BLUE-RED continuously in sequence.
2. If pairing with a PRYMEBLU adapter, place the adapter into pairing mode following the instructions in
the device's manual. Then proceed to step 5.
3. If you are pairing the microphone with a two-way radio, follow the manufacturer's instructions to have
the radio scan for nearby headset devices. Once it finishes scanning, select the device named "BTH-PTT"
from the list of nearby devices. Then proceed to step 5.
4. 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 then proceed to step 5.
5. Keep the radio or handset and headset near each other and wait a few seconds. The devices will pair to
each other.
NOTE that on some Kenwood radios you may hear a ring tone. If so, press the Phone Answer button on the
headset to confirm that pairing.
Reconnecting a Previously Paired Headset and Phone
Once the headset and handset have been successfully paired together, both devices will remember that
connection. They will reestablish their link whenever the headset and handset are both powered on and
within range of each other, as long as the BT radio is enabled in the handset. Re-establishing this
connection can take 10-60 seconds.
If the handset and headset to not automatically reestablish their link, simply press the handset button on
the PRYMEMAX headset to restore the connection.
