PARTS 11 AND 12 WITH YOUR FINGERS. To reduce battery consump-
tion your Cobra 700AF will switch over to standby mode after five
minutes. Simply press the camera's shutter button or the test flash
button (6) to restore power. For longer periods of time switch the
flashgun off using the ON/OFF switch (8).
Warning : There are no user-serviceable parts in this flashgun. Ex-
tremely high voltages are generated inside the unit, so never attempt
to dismantle or tamper with it. Any attempts to open the flashgun will
invalidate the guarantee.
HOW TO USE COBRA 700AF
1. LOAD THE BATTERIES
Slide the battery cover (4) towards the
front of the flash and insert the batter-
ies according to the diagram inside the
compartment. Close the cover by slid-
ing it firmly back into place.
Ensure that the batteries are fitted prop-
erly, and remove them when storing
the gun for a long period of time. The
majority of flash faults are caused by
leaking or incorrectly fitted batteries.
This flashgun takes four 1.5V AA size
Alkaline batteries or Ni-Cad equivalent.
We strongly advise against the use of Make sure the batteries are fitted
zinc-carbon batteries due to their short correctly
life and tendency to leak.
2. MOUNT THE FLASH ON THE
CAMERA'S HOT-SHOE
First switch off the gun. Then ensure
that the flash shoe module (13) is locked
in place, as marked on the flashgun.
Next rotate the locking wheel (10) up-
wards and slide the flash shoe into the
camera's hot-shoe until it's fully home.
There should be no need to force it
into place. Rotate the locking wheel
(10) downwards to hold the flash on
the camera.
Note:With Dynax version slide catch
