The Philips Norelco MG7790 is a versatile grooming tool designed for various trimming and shaving needs, offering a comprehensive solution for hair, beard, and body grooming. Its primary function is to provide precise and efficient hair removal and styling for different parts of the body, including the face, head, and body.
The device serves as a multi-groomer, capable of trimming hair to various lengths and achieving different styles. It features a full-size hair trimmer for general hair cutting, an extra-wide hair trimmer for larger areas, a precision trimmer for detailing and fine lines, a nose trimmer for unwanted nose and ear hair, and a precision shaver for clean edges and detailing beard styles. The wide array of attachments allows for a broad range of grooming tasks, from maintaining stubble and beards to full haircuts and body hair trimming.
The MG7790 is designed for cordless operation, providing flexibility and ease of use without being tethered to a power outlet. It can also be used directly from the power outlet if needed. The device is equipped with a battery status indicator that clearly communicates the battery's charge level: orange when almost empty, slowly flashing white during charging, and continuously white when fully charged. A quick charge feature allows for a single cordless trimming session after only 5 minutes of charging, while a full charge provides up to 6 hours of cordless operating time.
For different hair lengths and styles, the device comes with a comprehensive set of guards. These include stubble guards (1mm, 2mm), beard guards (3mm, 5mm, 7mm), an eyebrow guard (6mm), hair guards (4mm, 9mm, 12mm, 16mm), fading hair guards (4-9mm), and body guards (3mm, 5mm). These guards are easily attached and detached from the full-size or extra-wide hair trimmer, allowing users to achieve desired hair lengths and styles with precision.
When trimming beards, the guards are moved against the direction of hair growth, ensuring the guard's surface remains in contact with the skin for effective trimming. For body hair, it is recommended to use the green body guards, especially for sensitive areas, and to stretch the skin with a free hand while moving the guard against hair growth. The device is suitable for use on dry skin and hair, as wet hair can stick to the body.
For head hair, the extra-wide hair trimmer can be used without a guard for very close cuts or to contour necklines and areas around the ears. When shaping contours, only one edge of the cutter blades should touch the hair ends. Fading hair guards are specifically designed for trimming hair around the ears with a faded result, with instructions to hold the side of the guard with the short teeth closest to the ear.
The precision trimmer is ideal for creating fine lines and contours, used by holding the trimming head perpendicular to the skin and moving it with gentle pressure. The nose trimmer is designed for safe and effective removal of nose and ear hair, with a caution not to insert the tip more than 5mm. The precision shaver is used after trimming to remove remaining unwanted hairs and detail beard styles, by gently pressing it onto the skin and shaving along contoured edges.
A travel lock function is integrated to prevent accidental activation during storage or travel. This feature is activated by pressing the on/off button for 3 seconds, indicated by a flashing orange battery status light, and deactivated by pressing the button again for 3 seconds. The device also automatically unlocks when connected to an electrical outlet.
Maintaining the device is straightforward to ensure optimal performance and longevity. After each use, the product should be turned off and disconnected from the power outlet. All guards and cutting elements should be removed and rinsed under warm running tap water. The hair chamber can also be rinsed, and excess water should be shaken off before allowing all parts to air dry completely.
For a more thorough cleaning, the product handle can be wiped with a dry cloth. Any accumulated hairs in the hair chamber, cutting elements, and guards should be removed using the supplied cleaning brush. The nose trimmer head can be rinsed under hot water, and for stubborn hair/debris, it can be immersed in warm water for a few minutes before turning the product on to rinse it again.
The precision shaver requires specific cleaning steps: the top part is pulled off the bottom part, and any accumulated hair is blown or shaken out. The top part is then cleaned under warm tap water, excess water is shaken off, and it is reattached to the bottom part.
It is crucial to avoid using scouring pads, abrasive cleaning agents, or aggressive liquids like gasoline or acetone, as these can damage the product. Similarly, drying the trimmer teeth with a towel or tissue is discouraged to prevent damage. The product should be stored in the supplied pouch, ensuring it is dry and switched off, and the power cord should be removed before storage. The power cord and accessories should be stored in a safe location, away from potential damage.
