Safety Precautions

Use Caution to Prevent Hearing Loss

Outerloop contains a headphone

amplier that is more powerful than

the typical consumer product.

JK Audio products are designed for the broadcast industry. The broadcast professional must be able to hear headphone signals over the ambient noise level. From the cheering crowd at a football game to trackside at a car race, the program material or cues must be heard at high volumes without distortion.

Road Safety

Never use headphones while driving or cycling, etc. It can be dangerous to turn up the volume even while walking. Doing so may hinder your hearing and can be hazardous on the roadways or at pedestrian crossings.

Note: While Outerloop was designed to be very rugged and durable, it is not waterproof and care should be taken to keep the unit dry.

Overview

Introducing Outerloop

Outerloop™ functions as a wireless link to your intercom system. This universal belt pack provides connections for your existing 4-pin or 5-pin intercom headset, routing audio through your mobile device over a Bluetooth wireless connection. Use your cell phone to call into your intercom phone bridge or station phone coupler for a global wireless link.

Model OTL-F features both 4-pin and 5-pin Female XLR headset jacks, while model OTL-M features both 4-pin and 5-pin Male XLR headset jacks. Easy-touse send and receive level controls, a push-on, push-off Talk button, as well as a recessed sidetone level control. All the comforts of a standard belt pack whether you are around the corner or around the world. Outerloop also features a switch that selects between pairing to a phone or to a headset. In Phone mode, Outerloop pairs to your cell phone, notepad, or computer just like any other Bluetooth headset. In Headset mode, you can pair to another Outerloop or to a standard Bluetooth headset, providing a short range secure wireless point-topoint intercom. Outerloop to Outerloop connections default to HD Voice (120 Hz to 7 kHz) bandwidth. Many new Bluetooth wireless cell phones and headsets also provide HD Voice bandwidth.

Getting Connected

Send Level Control

Most Intercom Belt Packs do not include front panel transmit level controls. However, Bluetooth devices encompass a wide range of sensitivities, and therefore require an

extra degree of exibility.

Sidetone Null

A screwdriver slot on the side of the unit adjusts the amount of Sidetone (your voice coming back to you in your headset). This adjustment is made while by speaking into the headset with the Talk button engaged. Simply

insert a small at blade screwdriver

and adjust the trim pot to set the desired sidetone level.

Bluetooth Status LED

The blue LED on the front of the unit ashes in different sequences to indicate the

current connection status. When attempting to put the unit into Pairing mode, you should power the unit off then back on before pressing the Pair button.

If you put the unit into the wrong state due to releasing the button at the wrong time, holding it again for "X" seconds will not put it into the desired mode.

Bluetooth Wireless Technology

Pairing Mode

In Pairing Mode, any Bluetooth wireless technlogy enabled device within range can pair with your Outerloop. The blue LED will ash rapidly at a rate of 100ms off, 100ms on. Once the pairing process is complete the unique device ID is stored in Connection History. Subsequent connections can be made from Idle Mode.

Idle Mode

When the power switch is turned on, Outerloop starts in Idle Mode. In Idle Mode, Outerloop searches for paired devices. The blue LED

will ash at a rate of 2 seconds off, 200ms on.

Connected Mode

After bonding is complete, the blue

LED will ash at a slower rate of

2 secs off, 1 second on ( 2 secs

off, 4 secs on for HD Voice). The connection to that device is secure. Outerloop returns to Idle Mode when a connection is dropped or terminated.

Bluetooth Wireless Technology

Pairing to a Cell Phone with Bluetooth Wireless Technology

When you're rst connecting to a

new device, you should be in an environment with no other Bluetooth wireless technology enabled devices within range that might also be in Pairing Mode.

1. Starting with the Power switch Off,

set the Phone/Headset switch to the Phone position.

2. Turn the Outerloop on, then hold the Pair Button for 5 full seconds. After you release the button, the

blue LED should ash rapidly if

Outerloop is in Pairing Mode.

3. On your device, nd and select

the option to set up a connection. When the cell phone has found the new device, select from the list the device ID. Depending on the gender of model, the device ID is "JKOTLFxxxx" or "JKOTLMxxxx" where: xxxx = last four digits of the serial number.

4. If asked for a pin, enter "0000".

5. When bonding is complete, the blue LED will ash at a rate of 2 secs

off, 1 sec on. (2 secs off, 4 secs on for HD Voice) Once Outerloop

has been added to your cell phone, subsequent connections can be made more quickly from Idle Mode.

Bluetooth Wireless Technology

Pairing to a Headset with Bluetooth Wireless Technology

When you're rst connecting to a

new device, you should be in an environment with no other Bluetooth wireless technology enabled devices within range that might also be in Pairing Mode.

set the Phone/Headset switch to the Headset position.

2. Following manufacturer’s

instructions, set your Headset to Pairing Mode.

3. Turn the Outerloop on, then hold the Pair Button for 5 full seconds. After you release the Pair button,

the blue LED should ash rapidly if

Outerloop is in Pairing Mode.

Pairing Mode. The next time you pair to the same headset, you can connect from Idle Mode instead of Pairing Mode.

Bluetooth Wireless Technology

Connection History

Outerloop retains a history of the 16 most recent devices. To clear the connection history and return to factory reset, hold the Pair button in for at least 20 seconds. After resetting, Outerloop will return to Pairing Mode.

Outerloop Wireless Intercom Beltpack

Disconnecting from a device with Bluetooth Wireless Technology

Since Outerloop has no other function when Bluetooth is powered down, you may simply turn off the Power switch to disconnect from the Bluetooth device.

If you wish to leave Outerloop powered up while Bluetooth is powered down, simply press and hold the Pair button for 5 seconds.

When a Bluetooth connection is dropped or terminated, Outerloop returns to Idle Mode. If the unit is in Idle Mode for >2 minutes without a connection, Bluetooth will automatically shut off. You may restart Bluetooth by either turning the power switch off and on again, or pressing the Pair button for 2 seconds.

Bluetooth Wireless Technology

Reconnecting to a Device

When reconnecting to a device that is still in Outerloop’s pairing history, the device that will be in Headset mode

should be powered up rst and both

devices should be in Idle Mode. When the Master device is turned on, it will

nd the Headset device during its

power up cycle.

When reconnecting to your cell phone, the switch on Outerloop

should be set to Phone and the

Outerloop should be turned on rst.

When reconnecting to your Bluetooth headset, the switch on

Outerloop should be set to Headset and the headset should be turned

on rst.

Switching Between Phone and Headset

The Role Select switch is only monitored during the power-up sequence. You must power-down, select the desired function, then power-up for the change to take effect.

FAQs

What is the range of the Bluetooth transmitter/ receiver?

Outerloop will transmit and receive audio signals up to 40 feet (12 meters) from your Bluetooth device. The actual range is limited to the device with the shortest range. Transmitting signals over longer distances will require more power, therefore you should keep Outerloop as close as possible to your Bluetooth device to conserve battery power.

Can I pair my Outerloop to two cell phones and send my audio to two locations simultaneously?

No, your Outerloop can only connect to one Bluetooth enabled device at a time. Paired devices remain in the

Outerloop Wireless Intercom Beltpack

history for easy connection later.

How long will the battery last?

Based on our tests using a standard alkaline battery, the battery should last for >10 hours under backup power

. Lithium batteries can signicantly

increase the battery life, but at a higher cost. As an indicator of low battery, the red power LED will grow dim and then extinguish a short while before the battery is completely

exhausted and the unit shuts down.

FAQs

Can I use my Bluetooth headset with my cell phone while I have my phone connected to the Outerloop?

No, your cell phone can only be connected to one Bluetooth enabled device at a time.

My Outerloop won’t pair with my cell phone. Why won’t it accept the PIN?

If this is the rst time you have paired

the Outerloop with this cell phone, make certain you are in Pairing Mode and not Idle Mode. You must press and hold the Pair button on the Outerloop while turning the Power switch On. Hold for 5 seconds then

release to reach pairing mode the rst

time you connect.
