Use of Antennas

• FM, SW, VHF, UHF, AIR, UBD, CB: Extend the seven-section telescopic antenna or use an external antenna (3.5mm jack) for best reception. Shorten or set ATT to LOCAL if interference is strong.
• MW: Uses a built-in magnetic receiving antenna. Rotate the fuselage to find the best receiving position due to its directionality.
• External Antenna Input: Supports external input mode for MW band (54kHz to 1710kHz). Performance not guaranteed by manufacturer.

Electrical and Electronic Equipment Information for Private Households

This section provides information regarding the handling of electrical and electronic equipment, in line with regulations:

• Separate Collection of Old Devices: Electrical and electronic equipment that has become waste (old devices) must be collected separately from unsorted municipal waste. They do not belong in household trash but in special collection and return systems.
• Batteries, Accumulators, and Lamps: Users of old devices should generally separate batteries, accumulators, and lamps that can be removed without damaging the old device before handing them over to a collection point.
• Return Options for Old Devices: Owners of old devices from private households can return them free of charge to collection points of public waste disposal authorities or to return facilities established by manufacturers or distributors. Businesses with a sales area of at least 400 m² for electrical and electronic equipment, and food businesses with a total sales area of at least 800 m² that offer such equipment, are obligated to take them back. This applies even for distance selling if storage and shipping areas meet certain thresholds. Retailers must ensure convenient return options. A free return is generally possible when a new, equivalent device is purchased. For new devices delivered to private households, the old device can be collected free of charge. This applies to certain categories of devices (e.g., large appliances) when sold via distance selling. Consumers are asked about their intent to return when purchasing. Free returns are also possible at retailer collection points for small old devices (no external dimension larger than 25 cm), limited to three items per device type, regardless of new purchase.
• Data Protection Notice: Old devices often contain sensitive personal data (especially IT equipment). Users are responsible for deleting data on devices before disposal.
• Meaning of the "Crossed-out Wheeled Bin" Symbol: This symbol indicates that the device must be collected separately from unsorted municipal waste at the end of its lifespan.
