Important Information The ClockMINI (DF301) and ClockNAVI (DF311) combine a body fat monitor with a clock in a compact device that can be conveniently carried. The devices utilize the measurement of bioelectric impedance to estimate the body fat percent of the user. Because impedance is measured through the fingertips, the user does not need to remove his or her clothing.
WARNINGS ClockMINI (DF301) / ClockNAVI (DF311) utilizes a liquid crystal display which may leak a toxic fluid if the display is broken or cracked. This fluid may be harmful or fatal if swallowed. Use only the batteries specified in this manual and do not mix new and old batteries. Failure to do so could cause batteries to explode, or liquid leakage could occur resulting in damage to the device. Do not place device or batteries in an area where children have access.
CAUTIONS Do not disassemble ClockMINI (DF301) / ClockNAVI (DF311). This could result in damage to the device or malfunction. Do not place the ClockMINI (DF301) / ClockNAVI (DF311) at temperatures in excess of 60° C, or humidity in excess of 95% for extended periods of time, damage to the unit could result. Care for Your DF301 / DF311 Clean you ClockMINI (DF301) / ClockNAVI (DF311) with a damp cloth and household detergent. Do not use benzene, gasoline, or alcohol.
Body Fat Estimation What is Body Fat? Body fat, like protein, carbohydrates, vitamins and minerals, is an important nutrient. It stores energy for the body’s use, helps maintain body temperature and helps cushion and protect the internal organs. However, too much body fat can result in life-style related diseases. How Can You Detect Body Fat? People with a muscular build, such as athletes, can have a relatively high weight with little body fat.
Body Fat Estimation Body Fat Levels The ClockMINI (DF301) / ClockNAVI (DF311) uses the BIA method to calculate an estimate of your body fat percentage through a correlation formula that has been developed on the basis of scientific tests conducted by Yamato. Unfortunately, while several standards have been proposed, there is no consensus as to what ideal body weight, BMI or body fat percentage should be.
Features of the ClockMINI / ClockNAVI • The ClockMINI and Clock NAVI combine a body fat monitor with a fully functional clock. • The alarm function is useful for measuring at a certain time of day and can remind you to check your body fat percent at the same time of day, leading to more reliable results. • The compact size of the device makes it convenient for you to estimate your body fat at any time or place. • It is easy to handle, measures quickly, and display information in seconds.

Personal Data Storage There are four (DF301) or nine (DF311) memory registers for storage of your personal data (weight, height, age, gender, and formerly estimated body fat ratio and body fat level). There is also one register, 0, for temporary data. Temporary Data Memory register 0 will store personal data for one measurement.
Estimating Body Fat Percent CLOCK ALARM TIMER FAT % SET START Estimating without Stored Personal Data The DF301 / DF311 has a model set of data stored in it when it leaves the factory. You must enter your own personal data (weight, height, age and gender) before using the monitor. Button# 4 Press the FAT%/SET button. 2&3 Use the TIMER/T and ALARM/S buttons to select the desired register. If you do not want your data stored, use register 0. 4 Press the FAT%/SET button.
Correct Use of the Body Fat Monitor The correct posture when measuring. If not used with the correct posture, the DF301 / DF311 reading may not be accurate. Do not raise or drop your arms. Keep your arms straight. Keep a 90o angle between your arms and your body. Do not move your arms or body while measuring. Do not use while sitting or lying down. Hold each electrode firmly with your thumb and index finger. Keep your index and middle fingers apart. Do not let them touch each other.
Troubleshooting & Error Messages Problem The display is blank. The DF301 / DF311 does not function or display properly. The displayed body fat ratio is unusually higher or lower than previously estimated values. The estimated body fat ratios vary significantly. Possible Cause Are the batteries exhausted? Are the batteries installed with the correct polarity? The DF 301 / 311 may need to be reset. Are you using the correct posture and hand positions? Cannot get a steady reading.
Changing the Batteries If the display is blinking or if the display indicates “Lo”, then the batteries need to be changed. Press down on the T mark on the battery cover in the back of the monitor. Remove the two old batteries and replace with two new AA alkaline batteries observing the polarity indications in the battery case. Slide the battery case cover back into position. NOTE: Usually the stored personal data will not be erased when the batteries are replaced, though the clock will need to be reset.
