Figure 2-4. LED Light Location
The AC adaptor, when not in use, plugs into the back housing of the indicator. Figure 2-4 shows that location.
The Digital Chair Scale is capable of running its internal sealed lead-acid rechargeable battery if no additional
power source is available. Battery life is approximately 75 hours. If the
LO Bat
indicator is showing on the
display, recharge the battery or connect the scale to an AC power source as soon as possible for accurate
weighing.
Battery Charging
When the AC adaptor is connected to a power source, the rechargeable battery goes into recharge mode.
NOTE:
To maintain battery longevity we recommend you charge it on a regular basis rather than waiting until it is fully
discharged.
The LED indicator light on the back of the scale housing will illuminate red during the charging period, and
change over to green when the battery becomes fully charged.
