Caution
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.
注意
電池の交換は,正しく行わないと破裂する恐れがあります。
電池を交換する場合には必ず同じ型名の電池又は同等品と
交換してください。
使用済み電池は,取扱指示に従って処分してください。
UNLEADED SOLDER
This unit uses unleaded solder.
Boards requiring use of unleaded solder are printed with the lead free 
mark (LF) indicating the solder contains no lead.
(Caution:  Some printed circuit boards may not come printed with the 
lead free mark due to their particular size.)
: LEAD FREE MARK
Be careful to the following points to solder or unsolder.
•   Set the soldering iron tip temperature to 350 °C approximately. 
If cannot control temperature, solder/unsolder at high temperature 
for a short time.
Caution:  The printed pattern (copper foil) may peel away if the 
heated tip is applied for too long, so be careful!  
Unleaded solder is more viscous (sticky, less prone to 
flow) than ordinary solder so use caution not to let solder 
bridges occur such as on IC pins, etc.
•   Be sure to control soldering iron tips used for unleaded solder and 
those for leaded solder so they are managed separately. Mixing un-
leaded solder and leaded solder will cause detachment phenomenon.
SAFETY  CHECK-OUT
After correcting the original service problem, perform the following 
safety checks before releasing the set to the customer.
1.  Check the area of your repair for unsoldered or poorly-soldered 
connections. Check the entire board surface for solder splashes and 
bridges.
2.  Check the interboard wiring to ensure that no wires are “pinched” 
or contact high-wattage resistors.
3.  Look for unauthorized replacement parts, particularly transistors, 
that were installed during a previous repair. Point them out to the 
customer and recommend their replacement.
4.  Look for parts which, through functioning, show obvious signs of 
deterioration. Point them out to the customer and recommend their 
replacement.
5.  Check the B+ voltage to see it is at the values specified.
6.  Flexible Circuit Board Repairing
 
•   Set the soldering iron tip temperature to 350 °C approximately.
 
•   Do not touch the soldering iron on the same conductor of the circuit 
board (within 3 times).
 
•   Be careful not to apply force on the conductor when soldering or 
unsoldering.
1.  注意事項をお守りください。
 
サービスのとき特に注意を要する個所については,キャビ
ネット,シャーシ,部品などにラベルや捺印で注意事項を
表示しています。これらの注意書き及び取扱説明書等の注
意事項を必ずお守り下さい。
2.  指定部品のご使用を
 
セットの部品は難燃性や耐電圧など安全上の特性を持った
ものとなっています。従って交換部品は,使用されていた
ものと同じ特性の部品を使用して下さい。特に回路図,部
品表に0印で指定されている安全上重要な部品は必ず指定
のものをご使用下さい。
3.  部品の取付けや配線の引きまわしはもとどおりに
 
安全上,チューブやテープなどの絶縁材料を使用したり,
プリント基板から浮かして取付けた部品があります。また

サービスのために取外したネジ,部品,配線がもとどおり
になっているか,またサービスした個所の周辺を劣化させ
てしまったところがないかなどを点検し,安全性が確保さ
れていることを確認して下さい。
5.  チップ部品交換時の注意
 
・  取外した部品は再使用しないで下さい。
 
・  タンタルコンデンサのマイナス側は熱に弱いため交換時
は注意して下さい。
6.  フレキシブルプリント基板の取扱いについて

1-1.  WATER-PROOF, DUST-PROOF, AND SHOCK-PROOF
1-1-1. Water-proof, Dust-proof, and Shock-proof Performance
About water-proof, dust-proof, and shock-proof 
performance of the camera
This camera is equipped to be water-proof, dust-proof and shock-proof.
Damage caused from misuse, abuse or failure to properly maintain the camera is not 
covered by the limited warranty.
•  This camera is water-proof/dust-proof equivalent to IEC60529 IP58. The camera is 
operable up to a water depth of 5 m for 60 minutes.
•   Do not subject the camera to pressurized water, such as from a tap.
•  Do not use in hot springs.
•   Use the camera in the recommended operating water temperature range of 
–10°C to +40°C (14°F to 104°F).
•   Conforming to MIL-STD 810F Method 516.5-Shock standards, this product has passed 
testing when dropped from a height of 1.5 m above a 5-cm thick plywood board*.
* Depending on use conditions and circumstances, no guarantee is made regarding 
damage to, malfunction of, or the water-proof performance of this camera.
•   As for dust-proof/shock-proof performance, there is no guarantee that the camera will 
not become scratched or dented.
•  Sometimes water-proof performance is lost if the camera is subjected to a strong 
shock such as from being dropped. We recommend the camera be inspected at an 
authorized repair shop for a fee.
•  Accessories supplied do not meet water-proof, dust-proof, and shock-proof 
specifications.
Notes before using the camera under/near water
•   Make sure that no foreign matter such as
sand, hair, or dirt gets inside the battery/
memory card cover or multi-connector
cover. Even a small amount of foreign
matter may lead to water entering the
camera.
•   Confirm that the sealing gasket and its
mating surfaces have not become scratched.
Even a small scratch may lead to water
entering the camera. If the sealing gasket or
its mating surfaces become scratched, take
the camera to an authorized repair shop to
have the sealing gasket replaced for a fee.
•   If dirt or sand gets on the sealing gasket or
its mating surfaces, wipe the area clean with
a soft cloth that will not leave behind any
fibers. Prevent the sealing gasket from 
becoming scratched by touching it while 
charging a battery or using a cable.
•   Do not open/close the battery/memory card cover or multi-connector cover with wet 
or sandy hands or near water. There is a risk this will lead to sand or water getting inside. 
Before opening the cover, perform the procedure described in “Cleaning after using the 
camera under/near water”.
•   Open the battery/memory card cover and multi-connector cover with the camera completely dry.
•  Always confirm that the battery/memory card cover and multi-connector cover have been 
securely locked.
Notes on using the camera under/near water
•   The touch panel may be activated by water splashes on the screen icons. When using 
the camera under/near water, it is recommended that you hide the icons by touching   
on the right side of the screen. Touch   for a few seconds to display the icons again.
•  The touch panel cannot be operated underwater. Use the buttons of the camera to perform 
shooting operations.
•   Do not subject the camera to shock such as from jumping into water.
•   Do not open and close the battery/memory card cover or multi-connector cover while 
under/near water.
•  Use a separately available housing (Marine Pack) if going more than 5 meters under water.
•  This camera sinks in water. Place your hand through the wrist strap to prevent the camera 
from sinking.
•  Faint, white, circular spots may appear in under-water flash photos due to reflections off 
of floating objects. This is not a malfunction.
• Select 
 (Underwater) in Scene Selection to shoot underwater with less distortion.
•   If water drops or other foreign matter is present on the lens, you will be unable to record 
clear images.
•  Do not open the lens cover where the sand is whirling.
Cleaning after using the camera under/near 
water
•  Always clean the camera with water after use
within 60 minutes, and do not open the battery/
memory card cover or multi-connector cover 
before cleaning is finished.
Sand or water may get inside places where it
cannot be seen. If not rinsed, water-proof
performance will be degraded.
•  Allow the camera to sit in pure water poured into a cleaning bowl for about 5 minutes. 
Then, gently shake the camera, press each button, slide the zoom lever or the lens cover 
inside the water, to clean away any salt, sand or other matter lodged around the buttons 
or the lens cover.
•  After rinsing, wipe away water drops with a soft cloth. Allow the camera to dry completely 
in a shady location with good ventilation. Do not blow dry with a hair dryer as there is a risk 
of deformation and/or degraded waterproof performance.
•  Wipe away water drops or dust on the memory card/battery cover or terminal cover with 
a soft dry cloth.
•  This camera is constructed to drain water. Water will drain from openings around the 
ON/OFF (Power) button, zoom lever, and other controls. After removing from water, 
place the camera on a dry cloth for a while to allow water to drain.
•   Bubbles may appear when the camera is placed under water. This is not a malfunction.
•  The camera body may become discolored if it comes in contact with sunscreen or suntan 
oil. If the camera does come in contact with sunscreen or suntan oil, quickly wipe it clean.
•   Do not allow the camera to sit with salt water inside or on the surface. This may lead to 
corrosion or discoloration, and degradation of water-proof performance.
•  To maintain the water-proof performance, we recommend that once a year you take the 
camera to your dealer, or to an authorized repair shop, to have the sealing gasket of the 
battery/memory card cover, or of the multiconnector cover replaced for a fee.
