When the batteries on your Salter food scale run low, the screen will display a "LOW BATTERY" message. To keep your Salter food scale running smoothly, replace all of the batteries every time the batteries are low. If you will not be using the scale for an extended period, remove the batteries from the compartment and store them elsewhere. This will prevent corrosion from developing inside the battery compartment.
Turn your Salter scale off.
Turn the scale over on its back to reveal the battery compartment.
Open the compartment. Insert a fingernail in the depression in the compartment's edge and pull up, or simply slide the compartment forward, depending on your Salter food scale model.
Remove the batteries.
Insert new batteries into the compartment, orienting them correctly. Match the positive side of each battery with the positive symbol on the compartment and the negative side to the negative symbol.
Replace the compartment and turn on the scale.
Different Salter scale models take different batteries. Read your instruction manual for information on battery type. You can also remove the old battery and take it with you when you purchase a replacement.
