1.00 Safety Precaution:

User Manual Model:PS-7 DigitalPostalScale

ENGLISH Page: 3/8

Caution! Do overload the scale with a weight much heavier 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 over 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, get medical help immediately.

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

disassemble, taken apart, thrown into a fire or short-circuited.

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 like stove and heating radiators.

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

give list). When device cease function, please first check the batteries and replace if

necessary.

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

see if foreign substance is stuck in between the platform and main housing.

All scales comply with EC Directive 89/336 + supplements in Europe; in USA, the device is

FCC compatible.

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.

User Manual Model:PS-7 DigitalPostalScale

ENGLISH Page: 8/8

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

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

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, fully discharged 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 expect to be operated for several months or longer, users

should withdraw the batteries from the compartment, because battery leakage will

contaminate the contact causing the device loosing function.

Note: You will find these markings on

batteries containing harmful substances:

Pb = battery containing lead, Cd = battery

containing cadmium, Hg = battery containing

mercury.
