- Cuidado de la batería: For optimal battery life, avoid fully discharging the transceivers frequently. Recharge them regularly, especially if they will be stored for an extended period.
- Silicone Skins: The silicone skins can be removed and cleaned with mild soap and water if necessary. Ensure they are completely dry before reattaching them to the transceivers.
