KIT 3 SHOWN
CHARGING THE BLUE-MIC2-KU LAPEL MICROPHONE
The COBALT AV BLUE-MIC2-KU lapel microphone 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.

ACCESSORY
COBALT AV
ERBD
shown. Other

accessories are
listed below.
CLOTHING CLIP
The alligator-type clip secures
the COBALT AV BLUE-MIC2-KU
lapel microphone to the
user’s clothing during use.
The clip can be rotated to
allow the mic to be better
positioned.
PUSH-TO-TALK
BUTTON
This button is used
to activate
the push-to-talk
feature of the
AT&T EPTT app.
PHONE BUTTON
When the BLUE-MIC2-KU
is paired with a cellular
phone, this button can
be used to manage
phone functions such as
answering
or hanging up a call.
STATUS LED
The status LED
fl
ashes
messages that let the
user know the current
status of the device.
For a complete list of
the LED messages, see
page 7.
USB CHARGE JACK
This micro-USB jack is used to connect the supplied charge
cable to the BLUE-MIC2-KU in order to recharge the device’s
internal lithium-ion battery pack.
VOLUME UP/DOWN BUTTONS
These buttons can be used to set the volume level of the
earphone connected to the BLUE-MIC2-KU’s Earphone/Accessory
Jack.
BUILT-IN MICROPHONE
When the BLUE-MIC2-KU is
used with a listen-only
earphone, this microphone
picks up the user’s voice audio
to send over- the-air. When
an accessory containing a
microphone is used, the
internal microphone is muted.
EARPHONE/ACCESSORY JACK
Any standard 3.5 mm mono or stereo listen-only earphone can
be plugged into this jack. Received calls will be heard over the
earphone. This jack can also be used with a 3.5 mm 4-conductor
(Apple iPhone compatible) audio accessory that contains both
an earphone and a microphone such as Apple part numbers
ME186LL/A, or MD827LL/A. (Not included.) When used with such
an accessory, received calls can be heard over the accessory
earphones and transmit audio will be taken from the accessory
microphone.
POWER BUTTON
Pressing this button for one second turns the COBALT AV
BLUE-MIC2-KU lapel microphone on or o
ff
. This button is
also used to place the lapel microphone in pairing mode
so that it can be connected wirelessly to a cellular phone.
To charge the PRYMEBLU BTH-300-KU lapel microphone:
1. Ensure the BLUE-MIC2-KU Lapel Microphone is turned o
ff
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 side of the lapel
microphone. You will need to remove the protective rubber cover that is inserted into the charge jack.
(To prevent dust and moisture from damaging your lapel microphone, always ensure this cover is in
place when you are not charging the lapel mic.)
4. Once the charging process has begun, the LED indicator on the back of the BLUE-MIC2-KU Lapel
Microphone will show a continuous red light. When the battery is done charging, the LED light will
turn o
ff
.
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 COBALT AV
to get a new manufacturer-approved
replacement charger.
- Do not tamper with or modify the
BLUE-MIC2-KU lapel microphone or charger.
- Always turn the power switch to the o
ff
position
when charging the BLUE-MIC2-KU Lapel Microphone.
P-CBL-BT-USB charger cable and P-CHA-BT-USB

CONNECTING AN AUDIO ACCESSORY TO THE BLUE-MIC2-KU
LAPEL MICROPHONE
The COBALT AV BLUE-MIC2-KU lapel microphone 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.
In order to be able to hear incoming signals
received by the two-way radio or cellular phone,
the COBALT AV BLUE-MIC2-KU lapel microphone must
be used with a wired audio accessory that includes
an earphone. A COBALT AV KLSH ear bud-style
earphone is included with the lapel microphone kit.
However, many di
ff
erent optional wired audio
To connect an audio accessory to the BLUE-MIC2-KU
lapel microphone:
1. Plug the audio accessory into the 3.5 mm audio jack located on the top of the COBALT AV
BLUE-MIC2-KU lapel microphone. Make sure that the connector on the audio accessory is pushed all
the way into the jack on the lapel microphone.
2. You can adjust the volume of received signals by using the Volume Up and Volume Down buttons on
the lapel microphone or by adjusting the volume setting on the radio or cellular phone.
Optional Audio Accessories:
Although the BLUE-MIC2-KU KIT 1 includes a COBALT AV ear bud-style earphone, it is possible to use a
di
ff
erent audio accessory, if you wish. The 3.5 mm audio jack on the lapel mic will accept any mono or
stereo earphone with a 3.5 mm audio plug. You can also use any 3.5 mm 4-conductor (Apple iPhone
compatible) audio accessory that includes both an earphone and a microphone, such as Apple part
numbers ME186LL/A, or MD827LL/A (not included). If the audio accessory has a built-in microphone,
transmit audio will be taken from the accessory microphone.
