Communication error warning with the SB-R200
In the Commander mode
Using cords indicator
Incompatible camera warning
Incompatible lens warning
If, due to a weak battery etc., data communication fails
with either group A or B when using a camera not
compatible with CLS, even though the SU-800 and the
SB-R200 are properly connected, the corresponding
group (A or B) indicator blinks. The "Using cords"
indicator does not blink.
• If data communication fails with both groups A and B, the
"Err" indicator is displayed, and the "Using cords" indicator
blinks.
If the SU-800 is mounted on cameras not compatible
with CLS, the Commander function does not work.
Warning indicators appear if the Commander mode
is set.
• When the SU-800 is mounted on CLS-compatible cameras,
the SU-800 and SB-R200 will not work if these units are
connected using cords. Warning indicators will appear.
The SU-800 cannot be used with COOLPIX 8400 and
COOLPIX 8800 digital cameras, the Wireless flash
indicator blinks as a warning.
When used in combination with a non-CPU lens, if the
flash mode is set to AA, the AA mode indicator blinks
to warn you that the flash units in that group will
not fire.
