overloaded. A weight more than 9 divisions over capacity is
an overload condition.

2.0 General Scale Information
Read this user manual before using the scale so you understand the
operating features.
Do not overload the scale or throw heavy things on the scale. Damage
from overloading and abuse is not covered by the guarantee.
Keep the scale clean with a damp cloth and mild cleaning solution.
1. Set the scale on a level, solid surface and screw the base feet in or
out to bring the bubble to the center of the level.
2. Turn the unit on by pressing the ZERO key.
The beeper will sound, the display will show the version number
and the battery voltage level (dc-x.xx), then goes into the display
self-check ends with the ZERO annunciator lighting. The scale is
now ready to use.
3. To turn the scale off, press the OFF key. The scale will turn off
automatically after 10 minutes if the scale display is at zero and
there is no keypad operation. You can set the auto-off time in the
Configuration menu. See A-oFF on page 9. There is also a power
saving feature. After 40 seconds of scale inactivity the scale goes
into auto power saving mode and the display shows a small o. To
wake the scale up, place a weight on the scale platform.
4. If the battery voltage drops below 5.6V, the scale will turn off
automatically. There is a battery level annunciator on the left side of
the display. If three of the lights are lit, the voltage is 6.3V or higher.
If two lights are lit, the voltage is between 6.0V and 6.3V. If only one
light is lit, the voltage is lower than 6.0V and the unit should be
recharged.
5. Battery charging: Power is supplied by a built-in rechargeable lead
acid battery (6V/4.5Ah). It shows -bAtLo- when the voltage is low
and the scale is at zero. The scale can be used for a while, but the
battery should be charged as soon as possible.
To charge the battery, plug the AC power cord into an appropriate,
grounded outlet and charge for 12 hours.
If the scale is unused for a long period of time, charge the battery at
least every 3 months.
If after charging the battery life is very short, install a new battery.
6. If there is no active tare, you can zero the displayed weight if it is
lower than 4% of full capacity. To zero the scale, press the ZERO
key. The ZERO annunciator will light.
