You should choose the browning settings according to the type of bread you have:
• For dry, thin or stale bread, select a lower setting. This type of bread has less moisture and it will go brown quicker than moist, thick or fresh bread.
• For fruit bread like raisin bread, select a lower setting.
• For higher sugar content bread, select a lower setting.
• For heavier textured bread like rye bread or whole wheat bread, select a higher setting.
