6. Wait for about 10 seconds until on/off pattern of LEDs CR11 to CR18 becomes
steady.
7. Change the sending data pattern switch setting, S8 to S15.

Sending Data Pattern
If the on/off pattern of the LEDs CR11 to CR18 changes according to the
sending data pattern switch setting, the HSD works normal. The sending data
pattern switches S15 to S8 do not correspond to the LEDs CR11 to CR18
respectively. The synchronization of both patterns depends on the timing.
