BASE INSTALLATION / REMOVAL Product Name：Electric shaker bottle Test Model(s)：VOLTRX Chillmix POWER DISPLAY 18/8 STAINLESS STEEL Charging Port front back Electric Shaker BottleBaseCharging Cable Proper installation: The body and the base are tightly fitted together. KAA USE STEPS BUTTON OPERATIONS Add liquid Click the ButtonDrink smooth milkshake Add protein powder and other powders CLICK DOUBLE CLICK CLICK DURING MIXING 30 sec mixing 3 min mixing stop LONG PRESS FOR 5 SEC display battery level 250-550ml(9-18oz) one click:work for 30 seconds,double click: work for 3 minutes CLEANING METHOD CLEANING METHOD Remove the base Dishwasher washing Put the cup and lid upside down in the dishwasher Add warm water and dish soap Pour off water and rinse Clean the lid Click the button to start Usage Safety Battery and Charging 1.To avoid damage and injury,please never pour water above 160 degrees Fahrenheit into the bottle.Too high temperature will cause pressure accumulation during operation, and may break the sealing, to gush from the top. 1.Battery life mainly depends on your usage frequency. The statement of charge once for 1 mouth is calculated base on using 3 times a week under 30 sec mixing mode. Battery performance will gradually decline with the time of use. 2.When charging, LED indicator light will flash at current battery level, and all indicator lights are off after full charging. 3.At the end if mixing,if LED indicator lights turn off one after another, and the last LED light flashes quickly for 3 times ,it means the battery should be charged. Unable to start mixing, one LED flashes for 3 times No battery,please charge Mixing power is weak or mixing stops suddenly, and all LEDs flash for 3 times Low battery Excessive protein powder Improper base installation The base and bottle cannot be assembled Foreign matter in the notch Incorrect notch position 2.Please never heat the bottle in high temperature environment such as microwave oven and sterilization cabinet.Please never freaze this product. 3.Do not add dry ice, carbonated beverage and other liquids prone to generate high pressure. Do not add strong acid or alkali so as to prevent inner wall of container from corrosion. 4.Do not store dairy product or baby food in bottle for a long time. 5.Do not entirely soak the base in liquid for a long time to avoid failures.
