Somehow my tanita ultimate scale has been switched from pounds to stones. How can I get it back to pounds?

Q: Why does "st-lb" or "kg" appear when taking a measurement?
A: The unit's "Weight Mode" has been set to measure your weight in units of stone-pounds (st-lb) or kilograms (kg). Tanita's Body Fat Monitors and the UltimateScales can measure weight in three different modes: lb (pounds), kg (kilograms) or st-lb (British stone-pounds). To change the setting, first find out which model you have (it should be written just above or below the display screen of the unit).
Method 1
Body Fat Monitor/Scales: TBF-611, TBF-612, TBF-621, TBF-622, BF-541, TBF-560, TBF-572. UltimateScales: 2000, 2001, 2001T. BF-662, BF-555, BF-556, BF-558, BF-559, BF-625, BF-626.
Press the Set and Up Arrow buttons at the same time. Release the buttons, the display will flash. Press the Arrow button to cycle through each weight mode until just the mode that you require is displayed. Then press Set. The display screen will flash to confirm your selection and store in memory.
Note: If weight mode is set to pounds or stone-pounds, the height programming mode will be automatically set to feet and inches. Similarly, if kilograms is selected, height will be automatically set to centimeters.
Method 2
Body Fat Monitor/Scales: BF-542, TBF-551, TBF-521, TBF-531, BF-681, BF-682, BF-679, BF-680, BF-578, all Ironman products, and all InnerScan products.
Select the preferred weight mode by using switch on the back of the measuring platform.
Note: If weight mode is set to pounds or stone-pounds, the height programming mode will be automatically set to feet and inches. Similarly, if kilograms is selected, height will be automatically set to centimeters.

Change display from pounds to stones and pounds

I turned my scaled\s over and just above where the battery is located there is a little button...push it and it changes the lbs. to metric.
