2.1 Power Supply
Supply power to the main unit.
There are two ways to supply power; using power cord or battery.
-- Power Cord --
Plug the power cord into the connecting port located under the main power switch on the
rear of the unit.
AC100V~240V power supply line shall be used.
-- Battery --
Charge the battery in advance. You cannot charge the battery when it is installed in the
instrument. (Refer to 7. Battery Charge for charging the battery.)
Open the battery compartment cover on the rear of the instrument. To open the cover turn
the knob around 90 degrees. (Use a coin or something similar to turn it easily.)
Connect the battery to the connecter for rechargeable battery inside the battery
compartment.
When installing the battery, align the notch of the battery
socket with the notch on the instrument’s battery
connector cable.
Insert the battery as shown on the right picture (the connecter end should go to the rear
of the compartment), and turn the knob back to the original location to close the cover.
After supplying power using the power cord, switch ON the main power located on the
rear of the instrument. When using battery, turn this switch OFF.
When both the power cord is connected and the battery is installed, the instrument will
utilize AC power and will not discharge the battery.
