Item # XTDF4500
PLEASE READ BEFORE YOU USE THE FLASH
IMPORTANT NOTES FOR FLASH PHOTOGRAPHY
1. After each picture, wait for at least 4 -5 seconds for the
flash to be fully charged before taking the next shot even
though the ready light is on. This will help to prolong the
lifespan of the flash tube as well as to attain the full
charging capacity of the flash capacitor for precise flash
2. For precise flash output, it is best to wait till an
intermittent humming sound is heard before depressing
3. Maintain at least 6.6 ft. away from your subject.
4. In the event that the flash exposure is incorrect (over or
under exposed or green auto check light does not light
up), you may take either one or more of the corrective
action: (1) move closer to the object (2) re-adjust your
bounce angle (3) Increase ISO setting.
5. Bounce should only be used on lighter color ceiling.
Note that when using this feature, 2-3 f/stop of light will be
lost due to reflection.
6. Always use a fresh set of 4 batteries of the same brand
and type when old batteries are depleted. Mix and match
batteries of different types/brands will greatly deteriorate
7. When flash is not being used for extended period of
time (>2 weeks), remove all batteries to prevent battery
leakage. After batteries removal, do not expose the flash
unit and batteries to excessive heat such as fire or sun.
8. Charge up and test fire the flash unit at least once per
month to maintain the optimal performance of the flash
tube and charging capacitor.
Ensure the ON/OFF is in the OFF position. Insert 4 new
AA size batteries according to the battery polarity
indicated inside the battery chamber.
Note: This flash unit may halt and not function when the
battery power is not sufficient or when user operates this
unit inappropriately. Please switch it off by its main switch.
Wait for a few seconds and replace the battery if
necessary before switching it on again. This flash unit
should then work again as normal.
