Before You Start

  1. Accessing the Battery Compartment: Remove the thumb screw to detach the belt clip and access the battery compartment.
  2. Inserting the Batteries: The IEM-One Rechargeable comes with 2x rechargeable AAA batteries pre-installed. Ensure they are properly seated inside the compartment with correct polarity as indicated. The battery indicator LED will emit a red light when there is approximately 1 hour of use remaining.
  3. Recharging via USB-C: To recharge, connect a USB-C cable to the IEM-One Rechargeable unit and plug it into any standard USB power source. The built-in charging circuit will automatically begin charging the internal batteries (Batteries must be rechargeable!). A full charge typically takes about 3–4 hours, and yields up to 10 hours of usage time.
  4. Reattaching the Belt Clip: After checking the batteries or charging, reattach the belt clip and secure it with the thumb screw. Adjust the clip's tension by tightening or slightly loosening the thumb screw.
