I have a Healthometer digital scale Model 845KL when you step on it, it will weigh you the first time, then you have to pull the battery out and they it will work one time again and you have to keep pulling the battery each time to get your weight.

SOURCE: can't find instructions for Homedics digital scales SC-390

EACH BUTTON IS FOR FOUR INDIVIDUAL USER. BUTTON ALLOWS YOU TO INPUT IDEAL WEIGHT (FOUR GOAL WEIGHTS FOR FOUR INDIVIDUAL USERS). AND CALCULATE AGAINST ONE OF THE FOUR INDIVIDUAL ACTUAL WEGHTS. i AM USER 1 IN MY FAMILY. I HIT THE 1 BUTTON, WEIGHT AND MY GOAL WEIGHT COMES UP BEFORE MY ACTUAL.

SOURCE: Err 1 message on Taylor Lithium Elec Scale model 7346

This is a reply I received from Taylor customer support. I have followed this procedure enough times to wear out the original battery and still get the Err 1 message. You may have better luck.

Thank you for your e-mail. The reboot below may clear the error from
your scale. You may need to do this several times to completely reboot
the system. Please let us know if you have any questions or continue to
display the Error.


1. Remove the battery from the scale
2. Set the scale on the floor without the battery in place.
3. Stand on the scale for 10 seconds (still without the battery)
4. Carefully replace the battery without turning the scale on.
5. Using only one foot, tap the scale or apply just enough pressure to
turn on the display. (It should show dashes or zero's) IMMEDIATELY
REMOVE YOUR FOOT.
6. Let the scale turn off
7. Step on the scale for a weight reading

Welcome to FixYa!

1. The Platform on which you stand may be hitting the base of the scale. The corner that your heels are on is adjustable from the bottom of the base. Turn the scale over on its side and remove the round plastic foot. Insert an Allen wrench into the now exposed hole and turn the screw to raise that corner of the platform.

Note: If you adjust one corner, be sure to adjust the opposite corner to keep the platform levelor.

2. Look under the base of the scale and make sure no foreign item is lodged into the base and that no parts have come out of the base.

Thank you for using FixYa!
