⑶Custom Function : LCD display when power is switched on
With the C.Fn-11-1 set to [Retain power OFF status] (Fig.
021), the camera settings will not be displayed. This will
increase the number of possible shots to the same level
as the EOS KISS DIGITAL N.
＊ In the Full Auto mode, since you need not worry about the shutter
speed and aperture settings, using both C.Fn-11-1 and 〈DISP.〉 to
display the camera settings only when necessary will further save
battery power.
1.8 Built-in flash
The same flash unit (Guide No. 13) as the EOS KISS
DIGITAL N's is used. To prevent the built-in flash's
cover and fresnel from overheating and getting heat
damage, the flash firing is restricted (as shown in Table
008) after you take 20 consecutive flash shots at an
interval shorter than 10 sec. The degree of heating
is the same as with the EOS KISS DIGITAL N and EOS
30D, and this anti-overheating feature has been incorporated for product safety.
If this safety feature prevents a flash picture from being taken, the " buSY" icon appears in
the viewfinder and the "BUSY " icon appears on the LCD monitor.
＊ The EOS KISS DIGITAL N and EOS 30D also have a safety feature to prevent overheating after 20 continuous flash
shots. However, the cameras still immediately allows continuous flash shooting up to 20 shots if you let go of the
shutter button and press it again to shoot. Since the safety feature was not really effective in these two cameras, the
EOS D REBEL XTI / EOS 400D D now incorporates the above flash restrictions in both the single and continuous
shooting modes.
