With both the internal battery and the RE fully charged, the TCU shows the charge level as overlaying light bars, the
internal battery charge level is displayed with 10 blue light bars and the RE charge level is displayed with 5 green
light bars (Fig. 12.10 A).
The RE green light bars will overlay on the first 5 blue light bars of the internal battery light bars (Fig. 12.10 B) and
will hide some or all the blue bars depending on their state of charge. When the charge levels of both blue and green
bars are equal the green bars will show on top, as the charge levels drop, the color for the device with the lowest
charge level will show on top.
