1.00 Safety Precaution:

Caution! Do not overload the scale with a weight significantly greater than the maximum

capacity list in this booklet. Normally a load over 200% of the maximum capacity is likely to

damage the scale.

Do not keep weight/loading on the platform continuously, clean up / clear the platform when

you finish weight measurement.

Batteries are highly dangerous if swallowed. Keep batteries and scale out of reach of small

children. If batteries are swallowed, seek medical help immediately.

Batteries enclosed (if any) must not be recharged or reactivated by any means. Do not

disassemble, dismantle, throw into a fire or short-circuited batteries.

Keep children away from packing materials (danger of suffocation).

2.00 General notes for maintenance and troubleshooting:

The device is for personal/domestic use only and is not intended for medical or commercial

applications.

Place the scale on a firm level table/desk; a firm and level surface is preferable for correct

measurement.

The scale should be cleaned occasionally with a slightly damp cloth. Do not use abrasive

detergents and never immerse the scale in water.

Protect the scale against hard knocks, moisture, dust and chemicals. Keep away from heat

sources such as cooking appliances and heating radiators.

Repairs may only be carried out by Brecknell customer service or authorized dealers (per

attached list). When the device ceases to function, please first check the batteries and

replace if necessary.

When the scale gives an unsteady readout, please check alongside the weighing platform

to ensure that no foreign object is stuck between the platform and main housing.

All scales comply with Directive 2004/108/EC (EMC) + supplements in Europe; in USA, the

device is FCC compatible.

4.20 Weight measurement and Readout in different units

After the scale is turned on and unit type has been selected, users can place objects on

the platform for weight measurement. For example when the object is 5LB 12.5oz, then

the display will show in LB-oz mode:

If users require the result in metric or decimal LB units, press the selection key once and

the readout will toggle to metric 2622 gram

and next is 5.780 LB

4.30 Tare function

In case users need a basket / tray to measure the weight of several objects, they can

firstly place the tray on the platform and press the ON/OFF/TARE switch once. The scale

will clear the weight of the tray and reset zero in less than a second.

The scale can accept a maximum tare off weight of 2LB, if the tare off weight is higher

than this, the measurement capacity will be reduced by the difference.

4.40 Over Load Display

When loading is at or over the maximum capacity (7lb : 4.4oz ; 3299 gram ; 7.272lb), the

LCD display will show “-- - ” telling users that the measurement is out of range. Please

see below:

5.00 Low Battery Warning, Battery Disposal and replacement

5.10 Low battery warning

The device is able to sense if the batteries installed are in good condition for an accurate

measurement. 2 battery levels are assigned in the device: Good or Low.

When the battery voltage drops to or below 2.4V, a flashing sign will show:

In this case, the user will also see the empty battery icon blinking and once it

appears, the user should immediately replace the battery as the low battery

condition is likely to degrade the weight measurement and giving a poor

accuracy.

5.20 Battery Disposal and Replacement

Used batteries must be disposed of in a specially labeled collection container, at toxic

waste collection points or through an electrical retailer. You are under legal obligation to

dispose of batteries correctly.

When the scale is not expected to be operated for several months or longer, users

should withdraw the batteries from the compartment, as battery leakage may

contaminate the contacts and result in device malfunction.
