Cautions After Use
(Management Of The Balance)
Avoid mechanical shock to your balance.
Do not disassemble the balance. Contact your local A&D dealer if your balance needs service
or repair.
Do not use solvents to clean the balance. For best cleaning, wipe with a dry lint free cloth or a
lint free cloth that is moistened with warm water and a mild detergent.
Avoid foreign matter (dust, liquid or metal fragments) that could get inside the balance.

Cautions For Power Supply
Do not remove the AC adapter while the internal mass is in motion, for example, right after the
AC adapter is connected, or during calibration using the internal mass.
If the AC adapter is removed under the conditions described above, the internal mass will be
left unsecured, that may cause mechanical damage when the balance is moved.
Before removing the AC adapter, confirm that zero is displayed in the weighing mode, then
press the
ON:OFF key.
When the AC adapter is connected, the balance is in the standby mode if the standby indicator
is on. This is a normal state and does not harm the balance. For accurate weighing, we
recommend that you always plug in your balance so it can warm up.
Connect the AC adapter for
BM-22 and BM-20 normally.
