2 POWER indicator (green)
This lights when the unit is powered on.
3 BUSY indicator (yellow)
This lights while the disk drive is being accessed.
4 WARM-UP indicator (yellow)
If the temperature inside the unit is below about 5°C
(41°F), the warm-up circuit operates. This indicator
lights when the warm-up circuit is operating (until the
internal temperature reaches 5°C (41°F)).
This indicator also lights for about 2 seconds
immediately after the unit is powered on (during
internal circuit initialization).
If the ALARM indicator is on or flashing, this
indicator may also light to distinguish the problem.
(See "5 ALARM indicator".)
