3.2 Fitting the Ear Muffs

1. Extend the headband to its maximum length.
2. Place the ear cups over your ears, ensuring they fully cover your outer ears.
3. Adjust the headband by sliding the ear cups up or down until a comfortable and secure seal is achieved around your ears. The headband should rest on top of your head.
4. Ensure no hair or clothing interferes with the seal between the ear cups and your head, as this can compromise hearing protection.

4. Operating Instructions

To power on the Sordin Pro-X ear muffs, press and hold the central button on the keypad (refer to Figure 4.1) for approximately 2 seconds until you hear an audible confirmation tone. To power off, press and hold the same central button for approximately 2 seconds until you hear a different confirmation tone.

4.2 Volume Control

Adjust the amplification level of ambient sounds using the '+' and '-' buttons located on the keypad (refer to Figure 4.1). Press the '+' button to increase volume and the '-' button to decrease volume. Adjust to a comfortable listening level that allows for clear situational awareness without discomfort.

4.3 Sound Modes

The Sordin Pro-X features four selectable sound modes designed for specific environments:

• Hunting Mode: Optimized for detecting subtle sounds in natural environments.
• Focus Mode: Enhances speech clarity and reduces background distractions.
• Shooting Mode: Provides maximum impulse noise protection while maintaining awareness of commands.
• Communication Mode: Balances ambient sound amplification with clear two-way communication (requires external communication device, not included).

To switch between modes, briefly press the central button on the keypad. Each press will cycle through the available modes, indicated by an audible cue.

4.4 External Audio Input

The ear muffs are equipped with a 3.5mm audio input jack (visible in Figure 4.1) for connecting external audio devices, such as communication radios or media players. Connect a standard 3.5mm audio cable (not included) from your device to the input jack on the ear muff. The audio will be heard through the ear muffs.
