INSTALLATION, Cont.
Low Battery Indicator
When the batteries are near the point they need to be replaced (Alkalines) or recharged
(NiCad or NiMH), the low battery annunciator on the display will turn on (see Figure No. 5) If
the battery voltage drops too low for accurate weighing, the scale will automatically shut off
and you will be unable to turn it back on.
If using Alkaline batteries when the low battery annunciator turns on, turn the scale off, remove
the old batteries and replace with new ones. Follow the same procedure for installing batteries
when battery replacement becomes necessary.
If using NiCad or NiMH (and the QL&$G setup option is enabled, set to 1 or 2), plug the power
supply into the scale and then into the proper electrical wall outlet. The scale will begin
charging the batteries.
Battery Status
If batteries are used, the scale will show the battery status on power up. The display will show
E$WWU\ then change to ò << ò, where YY indicates the remaining battery voltage expressed
as a percentage (%) of the total battery voltage.
Battery Charging
To recharge the Ni-Cad or NiMH batteries, the power supply must be connected to a AC power
outlet and plugged into the scale. It will take approximately 15 hours to fully recharge the
batteries in the scale. While the batteries are charging the scale can still be operated. Note
that charging the batteries for more than 15 hours will not damage them.
When the scale is to be turned off, pressing the OFF key once will display “dashes" scrolling
across the display indicating the batteries are being charged. Pressing the OFF key again, will
display 2)) and turn the scale off. If the power supply is disconnected before the 15 hours,
the scale will continue to charge the batteries when the power supply is plugged back in. Note
that the auto-shutdown feature (if enabled during setup and calibration) will be disabled when
the scale is charging the batteries.
NOTE! When the scale is turned off, it is NOT charging the batteries.
Placing the Scale
After the batteries have been installed, the scale may be prepared for use. Place the scale on
a stable, vibration-free level surface away from direct sunlight and from any rapidly moving air
source (heating/cooling vents, fans, etc.). Make certain the power cord and peripheral cables
are routed out of the way of normal traffic. If the scale is unstable, adjust the front legs up or
down as necessary until the scale is stable.
CAUTION! Make certain that the structure beneath the scale is of sufficient
strength to hold both the scale AND the maximum load to be placed on the
scale. Failure of the supporting structure can result in an injury to the baby in
the baby tray, as well as damage to the scale.
Installation of the scale is now complete. Please read the operating instructions contained in
this manual before attempting to operate your scale.
