1.4 Low Battery Warning, Battery Disposal and Replacement
1.4.1 Low Battery Warning
The PS25 is able to sense if the batteries installed have enough voltage to provide an
accurate measurement. When the battery voltage drops to or below 3.8, Lo will flash
on the display
Figure 1.1 Low Battery Indication
Replace the batteries immediately as low battery condition is likely to degrade the
weight measurement and giving a poor accuracy.
1.5 Maintenance
lPlace the scale on a firm level table/desk. A firm and level surface is
preferable for correct measurement.
lThe scale should be cleaned occasionally with a slightly damp cloth. Do not
use abrasive detergents and never immerse the scale in water.
lProtect the scale against hard knocks, moisture, dust and chemicals. Keep
away from heat sources such as cooking appliances and heating radiators.
lRepairs may only be performed by Brecknell customer service or authorized
dealers. When the device ceases to function, please first check the batteries
and replace if necessary.
lWhen 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.
lThe scale complies with CE in Europe; and FCC in USA
DANGER!
BE SURE TO DISPOSE OF BATTERIES IN A SPECIALLY LABELED
RECYCLING CONTAINER OR TOXIC WASTE COLLECTION SITE.
CAUTION!
When the scale is not expected to be operated for several months, remove the
batteries from the compartment. Failure to do so may cause battery leakage
which will contaminate the contact causing the device to loose function.
