*1These functions are determined by the corresponding EEPROM / Register setting. Therefore the operations  
of ““ depend on the user’s setting.  
*2In Burst mode setting (RE_BURST_SET“1”, RE_SFP_SET”1”), it is assumed that only APC_FF  
function is used and no APC_FB function is used (Monitor PD, CURRALM and OPTALM are not used).  
[*3] Setting of RE_SFP_SET“0” and R_PWR_LVL1_SET“1“ is prohibited.
