Howard Leight Impact Sport Bluetooth Earmuffs (Model R-02545) Instruction Manual

Introduction

The Howard Leight Impact Sport Bluetooth Earmuffs, Model R-02545, are designed to provide hearing protection with integrated Bluetooth connectivity. These earmuffs feature a 21 dB Noise Reduction Rating (NRR) and digital compression circuitry with 5X sound amplification. The sound-activated compression has a rapid 0.5 millisecond reaction time. Bluetooth technology allows wireless device synchronization. The headset includes separate volume controls for Bluetooth audio and external environment amplification, utilizing two high-gain directional microphones. An AIR FLOW CONTROL design ensures a slim, low-profile ear cup for firearm stock clearance. The adjustable headband provides a secure fit, and the compact folding design allows for convenient storage. An automatic shut-off function engages after 4 hours to conserve battery life. The unit includes a rechargeable lithium-ion battery and a USB-C recharging cable.

Operating Instructions

1. Power On/Off

• To power on, press and hold the power button (usually located on one of the ear cups) until you hear an audible indication or see an indicator light.
• To power off, press and hold the power button again until the device shuts down.

2. Volume Control (Ambient Sound)

• Use the dedicated volume control dial or buttons for external environment amplification to adjust the level of ambient sounds.
• The two high-gain directional microphones will pick up sounds, which are then amplified up to 5X, allowing you to hear conversations and range commands clearly while protecting against loud impulses.

3. Bluetooth Pairing and Volume Control

1. With the earmuffs powered on, activate Bluetooth pairing mode (refer to specific button press sequence if indicated on the device, typically a long press of the Bluetooth button).
2. On your wireless device (smartphone, tablet), go to Bluetooth settings and select "Howard Leight Impact Sport" or similar from the list of available devices.
3. Once paired, you can stream audio or make hands-free calls.
4. Use the separate volume controls for Bluetooth audio to adjust the listening level without affecting the ambient sound amplification.

The earmuffs are equipped with an automatic shut-off feature that activates after 4 hours of inactivity to conserve battery life. Remember to manually power off the device if you finish using it sooner to prevent battery drain, especially for Bluetooth functions.

Maintenance

• Cleaning: Wipe the ear cups and headband with a damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure no moisture enters the electronic components.
• Ear Cushions: Periodically inspect ear cushions for wear and tear. Replace if damaged to maintain optimal noise reduction and comfort.
