To reduce the risk of fire or electric shock do not expose this apparatus to
rain or moisture. Do not expose the batteries to excessive heat for a long
period of time.
BATTERY INSTALLATION
- Take the earmuff cup (side with no electronics/buttons) and gently pull the cushioned ear muff ring.
- Remove foam cushioning
- Place batteries in the 3 slots as indicated. Insert the 3 AAA Alkaline batteries ensuring the polarity is correct according to the diagram inside the battery compartment. Incorrectly installed batteries could damage the unit.
- To close the battery compartment, replace foam cushioning and snap the earmuff ring securely in place.
ADJUST THE FIT
- Don the earmuffs with the controls over your right or left ear.
- Brush hair from beneath the cushions with your hand as much as possible.
- With the headband over the crown of your head, position the muffs to completely enclose your ears.
- Slide the muffs up or down to adjust for a firm, comfortable fit.
CAUTION! Foreign objects (such as pencils) between the ear cup and your head reduce the efficiency of the earmuff. Make sure the cushions seal tightly against your head. Do not reform or reshape the headband.

The factory has advised that without obstructions, the Bluetooth could reach
300 meters, which Is close to 900 feet. This seems like an awfully strong
claim. Not sure that we would leave it at that.

AUXILIARY JACK OPERATION
Connect external audio devices (such as an mp3 player) through the auxiliary
jack using a 3.5mm auxiliary jack cord (not included.) Once an external audio
device is connected, you can adjust the volume accordingly.
PLEASE NOTE:
- Speaker volume is limited to comply with OSHA regulations.
- Radio reception quality may be slightly distorted depending on the surroundings. To prevent damage to the radio, do not use it in a high-temperature or high-humidity environment for prolonged periods of time. To prevent damage to the hearing protector and radio within, do not subject it to rough handling.
PRECAUTIONS
- These headphones contain a noise-canceling feature. Noise-canceling senses the outside noise with a built-in microphone and sends an equal but opposite canceling signal to the headphones. The noise-canceling effect may not be as pronounced in a very quiet environment, or some noise may not be heard.
- The noise-canceling effect may vary depending on how the earmuffs are worn and work best for noise in a low-frequency band primarily.
MAINTENANCE
- Inspect the hearing protector regularly for cracks and signs of leakage. Earmuffs, in particular cushions, may deteriorate with use and age. Clean the outside of the muffs and cushions with soap and a damp cloth. Do not use abrasives or solvents.
STORAGE
- Ensure that the muffs are clean and dry before storage. Store the muffs at room temperature, away from dust. Do not store in direct sunlight. Exposure to direct sunlight in places such as car interiors, which may reach temperatures of up to 14of (6oc), may warp the product, affect the performance of the electronics, or lead to malfunctioning. Do not store where the temperature could drop below freezing. Do not extend the headband. To avoid uneven compression of the earcup cushion, ensure that the cushion lies flat against each other and that there are no creases in them. To prevent damage, remove the batteries.
TROUBLESHOOTING
- If the radio stops working: check for correct battery installation. Make sure the battery plates are clean and contact the batteries. Ensure the hearing protector is dry. If necessary, install new batteries.
