This document provides operating instructions for the Panasonic RB-HF520B and RB-HF420B digital wireless stereo headphones.
These headphones are designed for wireless audio playback and phone calls via Bluetooth® technology. They support "A2DP" (Advanced Audio Distribution Profile) for transmitting audio and "AVRCP" (Audio/Video Remote Control Profile) for remote control of the connected device. For phone calls, the headphones utilize the "HFP" (Hands-Free Profile), allowing users to answer and end calls using the unit's buttons. The headphones also feature voice functions, enabling activation of Siri or other voice assistants on the connected device.
Powering On/Off: To turn the headphones on, press and hold the [◎] button for approximately 3 seconds until the blue LED blinks. A beep will sound, and the blue LED will blink slowly. To turn them off, press and hold the [◎] button for about 3 seconds; an English guidance message will be heard, and the power will turn off. If not connected to a Bluetooth® device, the unit will automatically turn off after approximately 5 minutes of disuse.

Useful Functions:
Charging: The internal rechargeable battery is not initially charged.
Restoring to Factory Settings: To delete all pairing information and restore default settings:
Cleaning: Clean the unit with a dry and soft cloth. Avoid using solvents like benzine, thinner, alcohol, kitchen detergent, or chemical wipers, as these can deform the exterior case or remove the coating.
Keeping Battery Performance: For long periods of disuse, fully charge the unit once every 6 months to maintain battery performance.
Folding the Unit: The headphones can be folded for storage. Ensure the USB charging cord is disconnected before folding to prevent malfunction.
Resetting the Unit: If all operations are rejected, the unit can be reset by connecting it to a computer using the USB charging cord. This action will not delete pairing device information.
Battery Removal for Disposal: The manual provides detailed instructions for safely removing the battery when disposing of the unit. This process involves disassembling the right ear pad, removing screws and a plate, cutting cords, and carefully pushing the battery out with a non-pointy object. This is for disposal purposes only, as the unit is not restorable once disassembled. Always insulate battery terminals and dispose of batteries according to local regulations.
