Turning on the power
Remove the battery cover located on the bottom
of the PX4B by sliding it in the direction of the
arrow. Insert four AAA
alkaline batteries as
shown in the illustration.
Be sure to insert the bat-
teries observing the cor-
rect polarity.
Battery Low display
When the battery begins to run down, the Low
Battery icon
will light. When this icon lights, re-
place the batteries as soon as possible.
Programs and other data (except for the data
being edited) will not be lost even if the battery is
removed and changed.
Batteries that have run down must be removed
from the PX4B. If you leave dead batteries in
the unit, malfunctions (battery leakage, etc.) may
occur. You should also remove the batteries
when you do not expect to use the PX4B for an
extended period of time.
