4.5 CHARGING THE BATTERY
If your scale came equipped with the optional battery pack, follow this procedure to properly
charge your batteries.
NOTE: You should perform this procedure whenever the scale’s low battery annunciator
(BATT) turns on.
1. Push and hold the ON/OFF key for five seconds, then release or use the power switch to shut the
scale OFF.
2. Locate the battery charger switch on the rear panel of the scale.
NOTE: This may be hidden behind a metal plate held on by two drilled-head screws.
3. Position the switch as shown here:
4. Locate the AC adapter that shipped with the scale.
5. Connect the female end of the AC Adapter to the connector on the rear of scale, and then plug the
adapter into an AC outlet. Be sure to use the 24 VDC, 2A AC adapter that shipped with the
scale. Any other AC adapter may cause damage to the scale.
6. Allow at least three hours for the batteries to become fully charged. At the end of the charging
period, simply disconnect the AC adapter and resume normal use.
NOTE 1 : The batteries will be charged regardless of the setting of the power switch (ON or OFF). You
may continue to use the scale while the batteries are charging if you wish.
NOTE 2 : After charging the batteries, you may leave the battery charger switch in the position shown
above. If, however, you wish to store or ship the scale, you should position it the opposite way.
