BASIC OPERATION

Inserting batteries

Usable batteries - Alkaline batteries, Lithium batteries, NiMH batteries.

1. Remove the battery magazine and insert 4 x size AA batteries as shown in the picture.

1. The battery magazine is specially designed so that every battery is placed in the same direction to avoid the confusion in poor light condition.

2. +/- symbol is clearly marked at the battery compartment.

1. Place the battery magazine back into the body.

When the recycle time becomes longer than 20 seconds, replace the batteries with fresh ones or recharge the batteries (rechargeable batteries).

NOTE

It is recommended to use all 4 batteries in same brand and type, and replace them all at the same time.

Wrong insertion of each cell would not make electric contact.

Mounting MF18 on the Camera

1. Turn off the power switch of both MF18 and the camera

2. Loosen the lock ring of MF18 so the hotshoe mounts easily.

1. Slide the mounting foot of MF18 into the hotshoe of the camera from the back.

2. Turn the lock ring to opposite direction and tighten it.

1. Screw the adapter ring that is the same size as the lens onto the front thread of the lens.

1. Attach the flash head to the adapter. Press the release buttons on top and bottom of the flash head to insert the four mounting tabs on the inside of the flash head correctly into the groove on the adapter ring.

1. After the flash head is attached, pull it lightly to make sure the tabs are inserted into the groove correctly.

Expansion of the Flash Head

After the flash head has been attached, should you experience vignetting due to the flash covering a part of the lens, it is recommended that the flash ring be expanded to its wide position. This should eliminate the dark corners on the image. (It is also depending on the angle of view).

Remark: This Macro flash is preferable to apply on macro lens. For zoom lens, please adjust the suitable position to prevent the dark corners.

1. Press the expansion buttons on the sides of flash head.

2. The flash head is expanded. It is possible to expand one side if necessary.

1. To close the expansion, push it lightly back to the original position.

Removing MF18 from the Camera

- Loosen the lock ring and slide the mounting foot of MF18 off the hotshoe of the camera. Make sure to turn the lock ring all the way to completely clear the lock pin off the hooking slot on the hotshoe. Press the release button on the flash head and remove. Screw the adapter ring off the front thread of the lens.

Modeling LED lamps function

The modeling LED lamps with light ratio control, makes it easy to focus on the shooting subject. The brightness reflects flash power ratio setting of side A and B; therefore, the desired effect can be previewed.

1. To switch on the modeling LED lamps, press set Set for 2 seconds.
2. The LED lamps switch off temporarily when the flash fires, then switch on again for the next shoot. The icon (💡) is indicated on the screen.
3. To switch off the modeling LED lamps, press set Set for 2 seconds.

MF 18 has energy saving double power off function.

1. The power is automatically turned off (to stand-by mode), in about 30 seconds of idle use on the camera or after the last setting is made. To save the battery energy, you can select the display-off setting from the custom setting. In this case, the display screen turns off in about 8 seconds of idle use.

While MF18 is in the stand-by mode, display screen turns off and the pilot lamp blinks every 2 seconds showing the flash unit is in stand-by mode.

To turn on MF18 again, press the camera's shutter button halfway or press any button of the flash unit.

1. In case the MF18 is not in use over 30 minutes, the unit is completely turned off. To turn on MF18 again, take the first step of turning the flash unit on.

Remarks: Please be aware that calculating the f-number by dividing the guide number by the distance will not result in correct f-numbers when the distance is shorter than approx. 1 meter.

This calculation requires that the size of the light source is very small compared with the distance. This condition is not met at short distances. Therefore we recommend to use the TTL mode at short distances instead of manual mode with calculation of the f-number.

TROUBLE SHOOTING

The flash unit does not start charging.

● Batteries are not correctly installed

Re-install batteries to correct problem.
● Batteries are exhausted Replace the batteries if the recycle time is beyond 20 seconds

The flash unit does not flash.

• The flash unit is not firmly clipped on the camera

  Mount the flash unit firmly on the camera's hot shoe.
