Introduction

To achieve maximum battery capacity, BlueSet should
be fully charged before its first use. While this battery
will normally charge in about 2 1/2 hours, please allow
4-5 hours for this first charge. Connect the power
supply cable to the mini USB connector on the BlueSet
to charge the battery. The red LED will illuminate to
indicate when the battery is charging. Please see page
9 for more information. This device can be used with
the power cable connected if desired.

BlueSet connects directly to the headset jack on your
Party-Line belt pack unit, replacing the dynamic or
electret headset. Before you turn the BlueSet on, be
sure to set the Headset/Phone switch to the correct
position. If you change that switch while the unit is on,
you will need to power the unit off, then power the unit
on before the change takes effect.

Mode Switch

In the Bluetooth world, a device is either a Master (like
a cell phone, sound card or music player) or a Slave
(like a headset or car hands-free kit).

Select Headset if you will be using BlueSet with a
Bluetooth enabled headset or any device that emulates
a headset.

Select Phone if you will be using BlueSet with a cell
phone or other master device.

Bluetooth Wireless Technology

BlueSet will be activated when you press the Connect
button. The blue LED on the side of the unit will flash in
different sequences to indicate the current connection
status as described in the following sections.

Connecting to a Bluetooth Cell Phone

Set the Handset / Phone switch to the Phone position.
Establishing a Bluetooth connection varies with different

cell phones. On your phone, find and select the option to
set up a connection. Press and hold the brown Connect
button on BlueSet for at least 5 full seconds. After you
release the Connect button, the blue LED should flash
rapidly if BlueSet is in Pairing Mode.

Now go to your phone and search for Bluetooth devices.
If this is the first time you have paired with this device,
select the option to add an audio device. When the cell
phone has found the new device, select from the list the
device ID of "JKBSETgpxxxx" where:
g = XLR gender
p = XLR pin count
xxxx = last four digits of serial number

Bluetooth Wireless Technology

Enter “Yes” when asked to Bond with this device. Enter
the pin number as "0000".

When bonding is complete, the blue LED will flash at a
rate of 1 sec on, 2 sec off. Once BlueSet has been
added to your cell phone, subsequent connections can
be made more quickly from Idle Mode.

Tech Notes: There is a difference between “Pairing

Mode” and “Idle Mode”. The first time you connect
to a new device you must be in Pairing Mode.
When you hold the Bluetooth Connect button in for
about 2 seconds, the blue LED will begin to flash at
a rate of 200 ms on and 200 ms off. This first stage
is Idle Mode. Continue to hold the Connect button in
for another three seconds. After releasing the
Connect button, the LED flashes more rapidly,
about every 100 ms. This is Pairing Mode. You
must hold the Connect button in for a full 5 seconds
to reach Pairing Mode. Once in pairing mode, any
Bluetooth enabled device within range can pair with
BlueSet. After pairing is complete, the connection to
that device is secure.

The belt pack Mic/Talk button controls audio from the cell
phone into the intercom system.

Connecting to a Bluetooth Headset
Set the Handset / Phone switch to the Headset position.

The first time you connect to a new headset, you should
be in a “quiet” environment with no other Bluetooth
enabled devices within range that might also be in
Pairing Mode. Following manufacturer’s instructions, set
your headset to Pairing Mode. Hold the Connect button
on BlueSet in for at least 5 full seconds to activate
Pairing Mode. BlueSet will automatically pair to the first
device it finds that is in Pairing Mode. The next time you
pair to the same headset, you can connect from Idle
Mode instead of pairing mode. Please see “Tech Notes”
on page 5 for more information about these modes.

Connection History

BlueSet retains the most recent 16 headset and 16
phone devices in memory. To clear either connection
history and return to factory reset, from the power-off
state set the switch to the Headset or Phone position,
then hold the Connect button in for at least 20 seconds.
After resetting, BlueSet will return to pairing mode.

Power

Power On/Off

Pressing the Connect button will turn the BlueSet on.
To turn the power off, press and hold the Connect
button for a full five seconds. If left unused in Idle Mode
or if a live call is disconnected, BlueSet will automati­cally disconnect Bluetooth in two minutes and power
will be turned off.

Power Up Sequence

When reconnecting to a device that is still in BlueSet’s
pairing history, the device that will be in Slave mode
should be powered up first. Then when the Master
device is turned on, it will find the Slave device during
its power up cycle.

When reconnecting to your cell phone, the switch on
BlueSet should be set to Phone and the BlueSet should
be turned on first.

When reconnecting to your Bluetooth headset, the
switch on BlueSet should be set to Headset and the
headset should be turned on first.

Disconnecting from a Bluetooth Device
To disconnect from any Bluetooth device, simply press
the Connect button and hold for 5 seconds. If left
unused in Idle Mode or if a live call is disconnected, the
BlueSet will automatically disconnect Bluetooth in two
minutes and power will be turned off.

Power

Connect the supplied cable to the mini USB Power jack
on the side of the unit to recharge the internal battery.

If the battery is almost fully discharged when the power
cable is connected the red LED on the side of the unit
will light steady to indicate the unit is receiving a slow
charge. Then the red LED will blink while the unit
receives a full charge before it resumes a steady light to
indicate a slow charge to complete the charge cycle.

If the power cable is connected when the unit is shut
down, the blue LED will remain on steady. If the power
cable is connected while the unit is in use, the blue LED
will flash to indicate the current connect mode as
described on pages 4-7.

BlueSet contains a rechargeable Lithium-Ion battery.
These batteries do not have a “charging memory” and
can be recharged at any time without changing their life
expectancy. All rechargeable batteries have a limited life
and will gradually lose their capacity to hold a charge.
This loss of capacity is irreversible. To get the most from
your BlueSet, the battery should not be allowed to fully
discharge. If this unit is not in use, the battery should be
recharged at least every 90 days. The Lithium-Ion
battery in this device is not user replaceable. Please
contact JK Audio or a factory authorized service center
for battery replacement.

Other Features

A 3.5 mm stereo output jack contains a mic level signal
suitable for recording, with the beltpack headphone
signal on the left channel and the Bluetooth return audio
on the right.

A small flat blade screwdriver can be used to adjust the
Mic Trim pot on the back of the unit. This adjusts the
level of the audio coming from the Bluetooth device as it
is sent into the Belt Pack headset connector.

The XLR pinout on these devices is as follows:
Pin 1: Headset mic (low)

Pin 2: Headset mic (high)
Pin 3: Headphone (low)
Pin 4: Headphone (high)

Pin 5: Headphone (high) - for BlueSet-F5/M5
Note: Pins 4 and 5 are mixed together on the BlueSet-

F5/M5 to accommodate dual-sided headsets.

FAQs

? What is the range of the Bluetooth transmitter/

receiver?

! BlueSet will transmit and receive audio signals up

to 33 feet from your Bluetooth device. Maximum
range of the paired device also determines the
usable distance. Many cell phones and headsets
have a maximum range of 10 feet.

? Why can’t I get the BlueSet to accept a

password and pair with my new phone?

! If this is the first time you have bonded to this cell

phone, you might be in Idle Mode instead of Pair­ing Mode and your BlueSet is not being
recognized. You need to hold the Connect button
in for a full 5 seconds
first time. Please check pages 4-5 for more
information about Pairing Modes.
