Function Description
The Kunft portable radio is a compact device designed for receiving radio broadcasts. It supports both AM and FM bands, allowing users to tune into a wide range of radio stations. The radio is equipped with a telescopic aerial for FM reception and a built-in aerial for AM reception, ensuring optimal signal quality. It features a carrying handle for easy portability, making it suitable for use in various locations.

Additionally, it includes a headphone jack, allowing for private listening without disturbing others.
Important Technical Specifications
- Speaker: 3 inches, 8 ohm dynamic speaker, providing clear audio output.
- Power Output: 0.8W, indicating a modest power output suitable for personal listening.
- Battery Operation: DC 4.5V, requiring three "UM-2 / C" type batteries. This provides portability and allows the radio to be used in locations without access to mains power.

Usage Features
The radio is designed for straightforward operation with several user-friendly features:
- Power Supply Flexibility: Users can choose between AC power for continuous use at home or battery power for portability. The device automatically switches off battery supply when connected to the mains.
- Band Selection: A dedicated radio band selector allows easy switching between AM and FM bands.
- Tuning Control: A radio tuning control knob enables precise tuning to desired radio stations. The frequency scale provides a visual indicator of the tuned frequency.

- Headphone Jack: The 3.5mm headphone jack automatically mutes the loudspeakers when headphones are connected, facilitating private listening.
- Reception Improvement:
- For FM reception, the telescopic aerial can be pulled out, inclined, and turned to optimize signal strength. Its length can be reduced if the FM signal is too strong (e.g., near a transmitter).
- For AM reception, the built-in aerial means no external aerial is needed. Users can rotate the entire unit to find the best reception position.
- Portability: The integrated carrying handle makes it easy to transport the radio.
Maintenance Features
The manual emphasizes several key aspects of maintenance to ensure the longevity and safe operation of the device:
- Cleaning: Before cleaning, the appliance must be switched off, and the plug removed from the main power supply. The unit should be allowed to cool down. Only a dry, soft cloth should be used to clean the exterior of the product. The appliance should never be submerged in water.
- Battery Management: Batteries should be removed from the unit if it will not be in operation for extended periods to prevent leakage and damage.
- Cable Care: The power cord should not be tangled or pulled to disconnect the appliance. It should be kept away from warm surfaces. A damaged cable or socket should never be used; instead, it should be taken to a Technical Support Service for replacement.
- Environmental Protection: The manufacturer strives to reduce packaging volume, using easily sorted materials like cardboard, paper, and plastic. The appliance itself is made from recyclable materials and should be disassembled by a specialized company at the end of its life. Users are encouraged to comply with local regulations for material recycling.
- Professional Repair: In case of malfunction or damage, users are explicitly warned not to attempt repairs themselves due to the risk of electric shock. All repairs and maintenance operations must be carried out by authorized professionals or qualified engineers. Any manual modifications to the product or attempts at self-repair will void the warranty.
- Storage Conditions: The unit should not be exposed to extreme temperatures or high humidity to ensure normal functioning and a long lifespan. It should not be placed in bathing areas or near stoves or radiators.
- Water and Humidity: The appliance should not be used in humid places and must not be allowed to get wet under any circumstances to avoid fire hazards or electric shock. It should not be exposed to water or humidity.
The manual also highlights that the appliance can be used by children aged 8 and above, and by individuals with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, provided they receive instructions on safe use and understand the associated hazards. Children should not play with the appliance, and cleaning and maintenance should not be performed by children without supervision. The instructions are also available online at www.suporteworten.pt.
