Safety Information

Always read and understand all safety instructions before using the Peltor Alert M2RX7A. Failure to follow these instructions may result in hearing damage or other injuries.

• Ensure the hearing protector is properly fitted to achieve optimal noise attenuation.
• The level-dependent function is designed to amplify low-level sounds and attenuate high-level sounds. Do not rely solely on this function for protection in extremely high noise environments without additional precautions.
• Replace ear cushions and foam inserts regularly as per maintenance instructions to maintain hygiene and acoustic performance.
• Do not modify the hearing protector. Any modifications may compromise its protective capabilities.
• Store the device in a clean, dry place away from extreme temperatures.

The Peltor Alert M2RX7A requires two (2) AA batteries for operation. These are typically included with the product.

1. Locate the battery compartment on one of the earcups.
2. Open the battery compartment cover.
3. Insert two AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Close the battery compartment cover securely.

Adjusting the Headband

For optimal comfort and protection, adjust the headband to fit snugly over your head, ensuring the earcups fully enclose your ears.

• Slide the earcups up or down along the headband wires until the headband rests comfortably on the top of your head.
• Ensure the sealing cushions form a tight seal around your ears without excessive pressure.

Operating Instructions

Power On/Off and Volume Control

The main control knob on the earcup manages both power and volume for the radio and level-dependent function.

• AM/FM Toggle: A switch is provided to select between AM and FM bands.
• Reception: For optimal reception, ensure the antenna is extended. Reception quality may vary based on location and movement.

Level-Dependent Function (Tactical Function)

This feature allows for natural, spatial hearing by amplifying low-level ambient sounds and automatically attenuating impulse noise above 82 dB.

• Activate this function using the designated switch, typically located on the earcup.
• This allows you to hear conversations, warning signals, and machine sounds at a safe level, preventing a feeling of isolation.
