ISOtunes CALIBER Sport Hearing Earplug Instruction Manual

Location of Controls

No music volume control. Music/phone call volume is controlled by the device (ie. smartphone)

Tactical Sound Control™ Technology

This product includes TSC (Tactical Sound Control™) Technology. This is a microphone technology that allows the user to hear the world around them, but always at a safe listening level. When ambient noise breaches a safe listening level, the microphone technology immediately responds and attenuates to a safe level.

Adjusting the TSC Volume is easy. Simply tap the left earbud (2L) once for Aware Volume Up and tap the left earbud (2L) twice for Aware Volume Down.

Charging the Earbuds

There are three batteries to charge:

• Charging Case Battery
• Left Earbud Battery
• Right Earbud Battery

Place earbuds into the charging case. The earbuds’ LED Indicator Light (3) should be solid red, indicating that the earbuds are charging (if the LED Indicator Light (3)) doesn’t appear, refer to the troubleshooting section at the end of this manual).

Charging the Case

Insert USB C charging cable to charge the case. The Charging Case Battery Indicator Lights will start flashing to indicate the charge level.

Introduction
Thank you for purchasing ISOtunes® CALIBER True Wireless Noise-Isolating Earbuds. These earbuds have been specifically designed for use in noisy environments – allowing you to block out much of the surrounding noise so that you can listen to your music or talk on the phone with less interruption.

Power ON: Open charging case
Power OFF: Place earbuds into charging case and close the lid.

Method 2
Power ON: In OFF mode, press and hold MFB for 3 seconds.
Power OFF: In ON mode, press and hold MFB for 3 seconds.

Bluetooth Pairing
After powering on, the earbuds will automatically enter Bluetooth Pairing Mode. Look for quick red and blue flashes from the earbud as a confirmation. Open the Bluetooth settings on your device. Search for “ISOtunes CALIBER”. Pair and connect. You will
hear “Bluetooth Connected” once connected.

Charging
There are three batteries to charge:

1. Charging Case Battery
2. Left Earbud Battery
3. Right Earbud Battery

Charging the Case
Insert USB type C charging cable to charge the case. The charging case battery indicator light will start flashing to indicate charge level

Charging the Earbuds
Place earbuds into the charging case. The earbuds’ red indicator light should be solid red, indicating that the earbuds are charging.

Only charge your ISOtunes CALIBER with a Maximum 5 Volt charger. Using a charger higher than 5 Volts could be dangerous and may damage your ISOtunes product. Be especially careful with “quick charge” or “turbo charge” chargers, which often supply 9, 12, or 15 Volts. Your ISOtunes CALIBER cannot be charged at voltage levels above 5 volts.

Battery Capacity
ISOtunes® CALIBER supports Bluetooth® battery level indicator. This means that when connected to iOS devices, the battery power status can be seen in the upper right corner of the screen. Please use this as guideline – there are many factors to battery level accuracy that influence this measurement. (For example – although the battery power status may show 30% battery power remaining, this may actually only be 5-10% on your ISOtunes®.)

Noise Attenuation
This product has been tested to the European Safety Standard
EN352-2:2020 and the ANSI S3.19-1974 standard for a hearing protector, with a Single Number Rating (SNR) of 32 dB and a Noise Reduction Rating (NRR) of 25 dB. Full testing details are available in the Noise Attenuation section of this booklet.

ANSI S3.19-1974
The level of noise entering a person’s ear, when ISOtunes® CALIBER headphones are worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the Noise Reduction Rating (NRR). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fitting.

A1: Frequency (Hz)
A2: Mean Attenuation (dB)
A3: Standard Deviation (dB)

Example:

1. The surrounding noise level measured at the ear is 100 dB.
2. The NRR of ISOtunes® CALIBER is 26 dB.
3. The noise level entering the ear is approximately equal to 74dB.

Please note that the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise, such as gunfire.

EN 352
B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB)
B5:

H = Hearing protection estimation for high frequency sounds (f ≥ 2000Hz)
M = Hearing protection estimation for medium frequency sounds (500 Hz < f < 2000Hz)
L = Hearing protection estimation for low frequency sounds (f ≤ 500Hz)
