Note 1. <6> and <7> of 15-1 indicate RAM initialization. Set the contents to be displayed in the beginning. For
items not to be displayed (RAM Clear), use the following steps:
• DD RAM - write 20H (character code).
• CG RAM - write 00H (data ‘0’).
• Symbol register - write 00H (data ‘0’).
The RAM data is unspecified at the time of reset input (after power is turned on). If the data ‘0’ is not
written at this stage, unexpected display may occur to the unset position.
Note 2. Defined by the rising characteristics of the power circuit, time setting varies according to the external
capacity. So be sure to make confirmation by external capacity, and set this time.
Note 3. The dynamic drive system display lamp is lit up by the display on/off command when it is on. The static
icon lamp is lit by the static icon control command. So to light up the lamp simultaneously with start of
display, execute the display on/off control command and static icon control within one frame.
