Hi Ski, I have the exact same model and just figured out how to turn the auto shut off off. I’ve got the directions posted below (From their website). In addition to that feature, I love that it has the option to plug it in…I bought the adapter—love that. It’s also super compact, so it can fit in my narrow drawers. On the negative, the top plate comes off (some of the feet that secure it in place have broken), but now it’s easy to wash, so I suppose that is a positive. I don’t know that you would be able to put a 12 muffin tin on it and see the scale…actually I tried and it worked, but the back cups were not on the scale, so I just wouldn’t fill them 1st otherwise it would fall off the scale. Another negative is that if you do have it set to auto off, the scale resets, and my old one didn’t do this, so I accidentally lost some reads before I changed the auto shut off feature.
AUTO TURN OFF&AUTO; BACKLIGHT&BUZZER; CONTROL
Begin with the power OFF. Press and hold the MW center button and ON/OFF to turn on the scale, the display will show ?00000?, then it will show ?OFF 0?(disabled) or ?OFF 1?(automatic turn off after about 2 minutes) or ?OFF 2?(automatic turn off after about 5 minutes), select the auto turn off time by press UNIT. Now confirm your selection by pressing TARE. Now the display will show ?BL 0?(backlight turn off is disabled) or ?BL 1?(auto backlight will turn off after about 1 minute) or ? BL 2? (auto backlight-off after about 2 minutes), select auto backlight time by pressing UNIT , confirm it by pressing TARE . Now the display will show ?bb 0?(Beeper is disabled) or ?bb 1?(Beeper is enabled), choose your selection by pressing UNIT, confirm it by pressing TARE. The scale will return to active weighing.
