Note (1) The voltage of the lithium battery is checked when the power supply is turned ON, when
the battery voltage check signal (CHK) is turned ON for 1 ms or longer, or when the bat-
tery voltage check switch is pressed.
(2) If the battery voltage check signal (CHK) remains ON or if the battery voltage check
switch is pressed continuously, the POWER indicator will remain unlit and the PON out-
put signal will remain OFF. Use a pulse signal for the battery voltage check signal (CHK)
and do not press the battery voltage check switch continuously.
