HOW TO CHARGE THE INTERNAL BATTERY
1. Connect the charger (AC Adapter 12 VDC, 800mA) to the scale, and then plug the charger
into an AC outlet. Make sure that the AC voltage appearing at the wall outlet matches
the input voltage marked on the AC adapter.
2. After the charging period expires, unplug the charger from the AC outlet, then from the
scale. The scale is now ready for use under its own battery power.
NOTE: The charger may be left connected to the scale indefinitely without damage to the in-
ternal battery.
HOW LONG TO CHARGE THE INTERNAL BATTERY
In general, the battery should be allowed to charge a minimum of 1.5 hours for every hour of
use. If you discharge the battery below 50% and do not allow the proper time for charging, you
may start to notice a decline in the usage period. This is normal and eventually the battery must
be replaced.
REPLACING THE BATTERY
The recommended practice when removing the battery is to disconnect the ground connection
(black) first, then the red terminal. This ensures that a short circuit will not occur from a battery
lead or fuse lead touching the grounded housing while disconnecting the other terminal. Similar-
ly, the ground should be connected last when installing a new battery.
The US government has classified the internal battery as hazardous waste. Do not
place battery
into landfill. An automotive store or a local waste agency may accept the batteries for recycling.
Contact the manufacturer for more information.
Operation – weigh beams
Each beam contains two buttons and one LED.
The BLUE button is used to power up the beams
The RED button is used to power down the beams
The beams have several operating modes to save battery life and also to alert the user when its
time to replace the batteries. You can determine the operating mode by observing the blinking
behavior of the blue LED contained within each beam:
LED Functionality – Blinking interval
During Power-up (Initialization)
ON for 5 seconds
FULL BATTERY

Working Mode
1.5 seconds
Sleep Mode (power savings)
4 seconds
LOW BATTERY

Please replace the batteries when the blink interval is 10 seconds!
NOTE 1: Beams will shut down completely after two hours of inactivity.
NOTE: 2: Beams will only enter sleep mode when the indicator (display) is OFF.
