Measures to Prevent Accidental Flooding
The Z-240 is waterprool due to a rubber O-ring that seals the internal circuitry,
enabling underwater
us e.
Th is O-ring must be in spected each time belore using strobe to ensure waterprool
integrity. Equally important are O-ring contaci surfaces.
Al _ways check the
contaci surfaces lor contaminants or scratches.
O-Ring inspection locations
The lo cation ol user serviceable location is indicateci as lollows. Be sure to
check condition ol each O-ring including dust/loreign substances and condition ol
O-ring alter closing the battery box outer cap [the battery box O-ring must be
compressed unilormly]. Reler

O-ring Maintenance Method
Periodically re-grease the 0-rings fil1l.y using the supplied /NON Grease, to
protect O-ring and increase water resistance .
/NON yellow 0-rings are compounded with a special type of oil which naturally
migrates to the O-ring surface, but which is not compatible with a li grease types.
Do not use anv other qrease or other oil/fat containinq materiai, which may
cause the 0-rings to swell or deform, causing poor sea/ and water /eakage.
Use of non-INON grease will void warranty.
e . Svnch Connector Cap O-ring, Svnch Cord O- ring
Apply a little amount of grease on protuberant part of O-ring as it is seated in
th e groove. Be careful not to apply any grease on the electrical connector
or terminals of the Synch Cord.
e Battery Box O-ring
13
The battery box O-ring may be cui or damaged by friction, so add a little
extra grease lo the O-ring as it is seated in the groove , and a little on
Battery Box Cap O-ring contaci surface.
Also, slow/y rotate the battery box cap
whenever opening/closing Battery
Box ,
making sure you don't
feel any
excessive resistance, which could
mean the O-ring is binding or bearing
too much friction.
Be sure to complete inspection of O-ring de sc ribed in previous section
before greasing and confirm there is no contaminants andlor no damage
on O-ring .
O-ring itself could degrade in result of deformation, wear or aging . Periodica!
overhaul.al INON service facility is recommended also lor checking other parts
not serv1ceable by user. Please see 1 3. Alter Talking lmages -- Overhaul

lnstalling and removing O-ring
Your Z-240 strobe has been pressure tested, inspected and passed before
sh ipping. Il is now your responsibility lo prevent any water leakage by
properly maintaining the O-ring. lt may be necessary to remove the O-ring,
for cleaning or replacement. Accordingly, p/ease follow the next steps
carefully .
To remove, lightly squeeze from the sides
so it bulges out from one side, grasp and
pull off, as in figure at righi.
Clean any residuai grease or debris from
the O-ring groove and contaci surface, and
check the condition of both surfaces. Wipe
off O-ring to see if it
is sti li useable or noi.
Using your fingertips, apply a thin uniform
film of INON grease on the O-ring. Use a
new O-ring if the old one shows any cracks,
cuts or other degradation.
Gently install the O-ring in the O-ring groove,
not stretching it too much, and making
su re
it
is seated uniformly and not twisted. lf
you see any twists, take off and re-install.

Since Z-240 has higher power , it is likely to have overexposed image when
using a digitai camera equipping ordinary metering performance on its
built-in strobe (does noi allow lo make small flash) under particular
shooting situation below ;
e correct exposure can be obtained with ambient natural light
e macro shooting with open aperture
The overexposing can be prevented in most case by attaching r -0 .5 Whte
Diffuser 2 (TTL/Manual)J which also helps to widen flash beam angle from
1oo· lo 11 o· and soften light quality. So generally we recommend to
attachr-o .5 Diffuser 2 Jon Z-240 except you encounter insufficient flash light .
Please refer lo P. 42 of separate manual [ [Advanced Operation] 1. About

lor detail of supplied " diffuser ".
The r Red Filler · LEJ and rLight Filter Sticker · RedJ has two main funclions.
[Function 1] Helps noi lo scare away shy subjects.
[Function 2) Enables more accurate ~ S-TTL n Auto Exposure by minimizing
influence of Focus Light on camera 's automatic exposure
calculation in ultra macro shooting.
Roughly , ultra macro shooting with shooting distance less than
5cm/2in.(less than 10cm/4in. belween strobe and subject) in [ S-TTL n auto
mode without using rRed Filter · LEJ I rught Filter Sticker · RedJ may result
underexposure .
For strobe control modes other than [ S-TTU , il does noi matter il the rRed
Filter · LEJ I rFilter Sticker · RedJ is attached or noi. So first take a shot
without the filter/sticker and attach it if you need benefits of the
filter/sticker described above.

To ensure Z-240 proper performance il is important to properly aim Z-240 at a
subject. Be sure to confirm strobe aiming.
Also " Focus Light " assists and quickens camera's auto focusin Q so you can
obtain better images. With Focus Light set lo " Continuou s Mode " the light
will automatically shut off in sync with camera's preflash , and then
automatically turn on again 0.5 seconds later . Therefore , far shutter speed
longer than 0.5 seconds, light of Focus Light may be exposed in the image. In
this case, set Focus Light to " Single Mode " .
When using ~ Wireless ConnectionB , "Mirror Unii (strobe)" musi be adjusted
according
to the strobe position. For detail, reler to IWireless Connection KitJ

Adjusting Strobe Output in S-TTL Auto
37
Specific camera's flash characteristic and [specific shooting conditionsB or
depending on[ subject reflectivityD [personal preference tor type
of exposureB
etc. in some cases it may be preferable to ad ju st the flash output. Although
WS-TTU is an "auto exposure mode" i! is possible to fine !une flash output.
Adjust S-TTL settings according
!o Wcamera modelB , Wshooting conditionsB
etc. with Wactual adjustment methodsB as follows.
Shooting Conditions: Macro imaging less !han 30-40cm from a subject, with
Macro mode
on , and zoom a! telephoto end resulting
overexposing image (too brighi) ..
Adjustment Method: Change mode !o WL ow B (S-TTL "Low" mode) from WSTTU
(S-TTL mode). Then ad
ju st strobe output with "EV
Control Switch" as necessary.
Cause:
Shooting Conditions:
Adjustment Method:
Cause:
In these shooting conditions with specific camera carrying
ordinary underwater flash control, the camera.wi
ll
automatically stop down to f/14 - f/ 16 and automatica ll y
make the buil!-in strobe emit a full power flash, controlling
exposure by adjusting sensitivity of image sensor.
However, the Z-240 synchronizes with the camera's internal
strobe's full flash, which causes the overexposure.
Because the strobes
of th ese cameras w ill only emit a full
power flash when at full zoom in macro mode, the Z-240 w ill
try !o match thai intensity, so setto WS-TTL "Low"B mode.
Zoom at full wide position, much ambient light shoot from
lower angle (hard to meter subject reflectivity) resulting
underexposing image (too dark).
In WS-TTL ModeB if exposure cannot be effectively
adjusted with "EV èontrol Switch ", try changing the
came
ra 's built-in flash output by reducing tlìe proportion of
ambient light as follows.
· Adjust your position so more
of th e subject (less
surrounding ambient light) fills the frame and more
strobe light reflecting from the subject comes back to
the lens.
· Move the zoom a
Jittle towards telephoto makinq the
camera stop down its open aperture a little.
In these conditions,even if setto torce flash, specific camera
carrying poor underwater flash control accuracy,
wìll only lire
their flash weakly, no! enough to properly expose the image.
In WS-TTU and WS-TTL "Low"B modes, since the Z-240 is
dup li cating the same flash intensity as the camera's flash,the
flash
is too weak, making proportion ofambient light higher,
and resulting
in underexposed, dark images.
Despite such inadequate performance from such cameras
in these conditions,
i! is possible to adjust according to the Wsubject conditionsBand your Wpersonal
exposure preferencesB . Summary of adjustment methods in next page.

the ye ll ow line)
Rotating left towards WAB (plus) will increase flash output, making image
lighter.
(Plus compensati

yellow line)
e Adjust with two "S-TTL" modes ( [ S-TTU and [ S-TTL-"L ow "D l
WS-TTU mode operates until full fl ash under normai conditions.
WS-TTL-"Low"Bmode suppresses maximum flash output no! to make fu ll
flash even when used with a camera having ordinary light adjustment
accuracy
of built-in flash or poor underwater flash control capability.
When using with point and shoot compact camera, default position
of
[S-TTL-"Low "n mode will make overexposure less li kely to occur in the
situation mentioned above.
However, when insufficient light is expected (especially when the amount
of light close to full flash is necessary), WS-TTU mode should be used to
avoid underexposure.
With high-end cameras, you may set either the WS-TTL-"L
ow "BorWS-TTU
mode as the default. Settinq [S-TTU mode helps prevent
underexposure in the case mentioned below.
lf flash ou tput is expected too low like 1)-3), switch to [ S-TTU mode.
1) lf output stili too low after adjusting IEV Contro! SwitchJ to plus (+) side.
2) Attach 1-1 .5 DiffuserJ etc
3) Stop down camera's aperture setting
4) Subject is far away
e Adjust camera's rexposure compensation I , or ltlash compensa ti onJ
lf possible, use camera'sl Exposu re CompensationJfunction, or camera's
!Flash CompensationJ function.
Sometimes the effects of the camera's I Exposure CompensationJ and
I Flash CompensationJ function may be different. Or depending on the
Wcamera modelB or Wshooting conditionsB , th e effect may be different.
WBRposition of f EV Control SwitchJ is rough standard position tor ordinary
camera/shooting condition. You need to change to other position depending
on camera , condition of Optical Cable (wear of the cable etc.), optional parts
or shooting conditions. For example, WCRposition is preferable tor Olympus
C40Zoom.
Il is possible lo go directly lo set appropriate setting of f EV
Control SwitchJ and fMain Mode SwitchJ if you already know those setting
