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.

selected.
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.
