General Information

Thank you for purchasing the Model 405 scale. Please read all operating 

instructions carefully before using and note the following points:

• Avoid lengthy exposure to extreme heat or cold. The scale works 

best when operated at normal room temperature. Always allow the 

scale to acclimate to a normal room temperature before use. 

• Allow sufficient warm up time. Turn the scale on and wait a few 

minutes to allow the internal components to stabilize before 

calibrating or weighing. 

• The cleaner the environment the better. Dust, dirt, moisture, 

vibration, air currents and proximity to other electronic equipment can 

cause an adverse effect on the reliability and accuracy of your scale. 

Only use on a stable, vibration free surface. 

• Handle with care. Gently apply all items to be weighed onto the 

weighing platform. Although this scale is designed to be quite 

durable, try to avoid rough treatment as this may permanently 

damage the internal sensor.

• Place the item to be weighed on the platform and after the stable 

weight is displayed, remove the item immediately. This will aid in the 

longevity and accuracy of this weighing instrument.

• Do not operate near an in-use cell phone, radio, computer or other 

electronic device as these devices emit radio frequency (RF) and 

may cause unstable scale readings. 

• Level the scale by looking at the bubble level under the display and 

adjusting the feet on the bottom of the scale.

• The scale may be powered by an AC adapter or a 6-volt 

rechargeable battery. When Lo.bAt is flashes on the display, the 

battery is low. Please recharge battery immediately.
