Confirm that no foreign matter is attached, apply a thin coat of the

accessory grease to the O-ring, and fit the O-ring into the groove. At this

time, confirm that the O-ring does not stick out from the groove.

1

Apply the specified 
grease.

Make sure there is no dirt on your fingers 
or on the O-ring; then squeeze about 
10 mm of grease onto your fingertip.

2

Spread the grease over 
the O-ring.

Using two fingers and a thumb, spread 
the grease over the O-ring while rubbing it 
in. Use caution not to squeeze or pull the 
O-ring too hard.

3

Check that there is no 
damage or irregularities 
on the O-ring.

Once the grease has permeated 
throughout the O-ring, check it for 
damage or irregularities (both visually and 
by touch). If you notice any abnormalities, 
replace the O-ring with a new one.

4

Apply the grease to the 
O-ring contact surface.

Use any residual grease on your 
fingertips to clean and lubricate the O-ring 
contact surface on the flash.

• Always perform maintenance of the waterproof function even when the

battery cap has been opened to exchange the battery. Neglecting this

maintenance may result in water leakage.

• When the flash is not to be used for a long time, remove the O-ring from

the groove to prevent deformation of the O-ring, apply a thin coat of silicone

grease, and store it in a clean plastic bag.

• When drying is done with salt attached, it is likely that a function

impairment will be caused. After use, always wash off any salt.

Examples of foreign matter sticking to the O-ring

Hair

Fibers

Grains of sand
