EN · Instruction manual UNI BLACK KS1B-T2 4 EN INSTRUCTION MANUAL · UNI BLACK IMPORTANT SAFETY INSTRUCTIONS •Read this manual thoroughly before using and save it for future reference. •This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. •Children shall not play with the appliance. •Cleaning and user maintenance shall not be made by children without supervision. •This product is intended for indoor, non-industrial, non-commercial, household use only •Always place the object to be weighed at the centre of the kitchen scale. •Do not place any object on top of the scale before switching the appliance on. 5 EN PRECISION SCALE · KS1B-T2 • Clean the scale with a slightly damp cloth. Do not use chemical/abrasive cleaning agents. • Switch off the power button on the side of the scale if the scale is not being used for a long period. • Never immerse the appliance into water or any other liquid. • Keep the scale in a cool dry area. •Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. •Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in 6 EN INSTRUCTION MANUAL · UNI BLACK accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. •To maintain compliance with FCC's RF exposure guidelines, the distance must be at least 20cm between the radiator and your body, and fully supported by the operating and installation configurations of the transmitter and its antenna(s). 6 EN INSTRUCTION MANUAL · UNI BLACK PRODUCT OVERVIEW 1.Scale Included: Heat resistant silicon pad USB-C cable 1 FUNCTION DESCRIPTION HEAT RESISTANT SILICON PAD Sudden rise in temperature might affect the accuracy of the scale. We therefore recommend using the heat resistant silicon pad for optimum accuracy during brewing and measurements of hot liquid. The pad is also intended to be used to protect the scale during measurements and as a support when measuring directly into a portafilter. 7 EN PRECISION SCALE · KS1B-T2 FULL DISPLAY LAYOUT TURN ON SCALE • Make sure the power switch on the back is set to on position. • Then short press the power button on the display to turn the scale on. • The timer and scale button fades in, and the scale is ready to use. TARE FUNCTION • The scale tares automatically when it starts. • Place the coffee container on top of the scale, press the scale button to tare the weight of the container, and the scale will show 0.0g/oz. The scale is now ready to measure any additional weight. • Remember to use the heat resistant silicon pad if you are brewing or weighing any hot liquids. CHANGE WEIGHT UNIT Long press the scale button for 3 seconds to switch between grams (g) and ounces (oz). TIMER • The timer does not show when starting the scale. Short press the clock- button to show the timer. • Short press the clock-button again to start the timer. To pause the timer, short press the clock-button and the time will freeze. • To reset the timer long press the button for 1 second. AUTO OFF If you stop adding weight to the scale, it will automatically shut off after 10 minutes. 8 EN INSTRUCTION MANUAL · UNI BLACK TROUBLESHOOTING OVERLOAD WARNING The scale is overloaded, remove weight from the scale (maximum weight is 2000g). UNSTABLE WARNING Unable to activate the scale because the scale is unstable. Place the scale on a flat and level surface. BATTERY STATUS • If the battery is 10% or lower when the user is turning on the scale this warning shows on the display. The warning is visible for 2 seconds before the scale turns on. • To show battery status, long press the on/off button for three seconds, and the battery percent will show before the scale turns on/off. 9 EN PRECISION SCALE · KS1B-T2 CHARGING To charge the scale, plug the USB cable into the USB port located at the back of the scale. Make sure the power switch on the back is set to on position before charging the device. When charging, the display only shows the battery percent. CLEANING Clean the scale with a soft slightly damp cloth. Never use hot water or any harsh chemicals. STORAGE • Turn the power switch off. • Ensure that there is nothing on the scale when it is not being used. • The scale should not be stored standing on its side • Never attempt to open the scale and tamper with its mechanism or circuitry BLUETOOTH The scale comes with a built in Bluetooth® device. This feature gives the user the possibil- ity to read and control the scale from a smartphone device (iOS or Android). If a Bluetooth connection is made, the B lights up on the display. Follow these steps to connect your smartphone to the scale. 1. Download the “Wilfa SVART” app from App Store® or Google Play™. 2. Turn on the scale by pressing the power button 3. Open the app on your …
