Preliminary Preparations

1. Loading the Batteries

Use four, new, size-AA alkaline (LR6) or Nl-Cd batteries. Carbon-zinc batteries may also be used, but their life is shorter. Wipe the battery terminals with a clean, dry cloth to ensure proper contact.

1)Slide the battery chamber cover down In the direction of the arrow to open.

2)Load the batteries so that their terminals face In the directions indicated by the diagram inside the battery chamber.

3)Finally, push the cover completely down and slide it back to close.

• When the batteries become exhausted, replace all four at the same time with the same brand.

>Remove the batteries if you do not expect to use the flash unit for about three weeks or longer.

>Battery performance deteriorates in cold temperatures below 0'’C/32°F so please keep the batteries warm until just before use. For best results, use fully-charged Ni-Cd batteries in cold temperatures below 0°C/32°F

' When using Ni-Cd batteries, please note that various brands have different types of ter­ minals. Be sure to use a suitable type. Recharge Ni-Cd batteries according to the manufacturer's instructions.

2. Mounting the Flash on the Camer;

1) Loosen the lock nut and slide the flash unit into the camera's accessory shoe. To ensure correct electrical contact, make sure it is pushed in all the way.

2) Tighten the lock nut.

3. Ready Lamp and Test Firing

Turn the main switch ON (“I" mark) and wait for the ready lamp to light up To test func­ tioning, press the ready lamp after it has lit and if the flash fires it is in proper working order

If the camera is turned on, test firing does not function.

Flash charge is also confirmed by the mark in the viewfinder.

When the shutter button is pressed halfway, the flash head position automatically adjusts (see p9)

SE (Save-Energy) Function

O &M>

I_______ - i

Turn the main switch OFF (“O" mark) when flash photography is finished to prevent un­ necessary battery consumption. The Speediite 300EZ has a built-in SE (SaveEnergy) function that automaticaily turns off power when the flash is not used for approx­ imately five minutes (test firing, preflash, etc.). Press the shutter button halfway down to re-start the flash.

• For interval flash photography, attach the Technical Back E and set the mode to the inter­ val timer or self-timer. The flash charge starts automatically one minute before shutter release.
