DImage Sensor Cleaning
Using camera controls during startup interrupts image sensor 
cleaning.
 Image sensor cleaning may not be performed at startup if 
the flash is charging.
If dust can not be fully removed using the options in the  Clean image 
sensor  menu, clean the image sensor manually ( 0448) or consult a 
Nikon-authorized service representative.
If image sensor cleaning is perf ormed several times in succession, 
image sensor cleaning may be temp orarily disabled to protect the 
camera’s internal circuitry.
 Cleaning can be performed again after a 
short wait.

7Clean the sensor.
Remove any dust and lint from the 
sensor with a blower.
 Do not use a 
blower-brush, as the bristles could 
damage the sensor.
 Dirt that can not 
be removed with a blower can only 
be removed by Nikon-authorized 
service personnel.
 Under no circumstances should you touch 
or wipe the sensor.
8Turn the camera off.
The mirror will return to the down position and the shutter 
curtain will close.
 Replace the lens or body cap.
DUse a Reliable Power Source
The shutter curtain is delicate and easily damaged. If the camera 
powers off while the mirror is raised, the curtain will close 
automatically.
 To prevent damage to the curtain, observe the 
following precautions:
• Do not turn the camera off or remo ve or disconnect the power source 
while the mirror is raised.
• If the battery runs low while the mi rror is raised, a beep will sound 
and the self-timer lamp will flash to warn that the shutter curtain will 
close and the mirror will be  lowered after about two minutes.
 End 
cleaning or inspection immediately.

DForeign Matter on the Image Sensor
Nikon takes every possible precaution to prevent foreign matter from 
coming into contact with the image sensor during production and 
shipping.
 The D810, however, is designed to be used with 
interchangeable lenses, and foreign matter may enter the camera 
when lenses are removed or exchanged.
 Once inside the camera, this 
foreign matter may adhere to the image sensor, where it may appear in 
photographs taken under certain conditions.
 To protect the camera 
when no lens is in place, be sure to replace the body cap provided with 
the camera, being careful to first remove all dust and other foreign 
matter that may be adhering to the body cap.
 Avoid exchanging 
lenses in dusty environments.
Should foreign matter find its way onto the image sensor, clean the 
sensor as described above, or have  the sensor cleaned by authorized 
Nikon service personnel.
 Photographs affected by the presence of 
foreign matter on the sensor can be retouched using the clean image 
options available in some imaging applications.
DServicing the Camera and Accessories
The camera is a precision device  and requires regular servicing. Nikon 
recommends that the camera be inspec ted by the original retailer or 
Nikon-authorized service representative once every one to two years, 
and that it be serviced once every three to five years (note that fees 
apply to these services).
 Frequent inspection and servicing are 
particularly recommended if the camera is used professionally. Any 
accessories regularly used with the ca mera, such as lenses or optional 
flash units, should be included when the camera is inspected or 
serviced.

Do not drop: The product may malfunction if subjected to strong shocks or 
vibration.
Keep dry : This product is not waterproof, and may malfunction if 
immersed in water or exposed to high levels of humidity.
 Rusting of the 
internal mechanism can cause irreparable damage.
Avoid sudden changes in temperature : Sudden changes in temperature, such 
as those that occur when entering or  leaving a heated building on a cold 
day, can cause condensation inside the device.
 To prevent 
condensation, place the device in a ca rrying case or plastic bag before 
exposing it to sudden changes in temperature.
Keep away from strong magnetic fields : Do not use or store this device in the 
vicinity of equipment that generates strong electromagnetic radiation 
or magnetic fields.
 Strong static charges or the magnetic fields 
produced by equipment such as radio transmitters could interfere with 
the monitor, damage data stored on the memory card, or affect the 
product’s internal circuitry.
Do not leave the lens pointed at the sun : Do not leave the lens pointed at the 
sun or other strong light source for an extended period.
 Intense light 
may cause the image sensor to deteriorate or produce a white blur effect 
in photographs.
Caring for the Camera and Battery: 
Cautions 
						

							453
Cleaning: When cleaning the camera body, use a blower to gently remove 
dust and lint, then wipe gently with a soft, dry cloth. After using the 
camera at the beach or seaside, wipe  off any sand or salt using a cloth 
lightly dampened in pure water and then dry the camera thoroughly.
 In 
rare instances, static electricity may cause the LCD displays to light up or 
go dark.
 This does not indicate a malfunct ion, and the display will soon 
return to normal.
The lens and mirror  are easily damaged.
 Dust and lint should be gently 
removed with a blower. When using an aerosol blower, keep the can 
vertical to prevent discharge of liquid. To remove fingerprints and other 
stains from the lens, apply a small amount of lens cleaner to a soft cloth 
and wipe the lens carefully.
See “Image Sensor Cleaning” ( 0445) for information on cleaning the 
image sensor.
Lens contacts : Keep the lens contacts clean.
Do not touch the shutter curtain : The shutter curtain is extremely thin and 
easily damaged.
 Under no circumstances should you exert pressure on 
the curtain, poke it with cleaning tools, or subject it to powerful air 
currents from a blower.
 These actions could scratch, deform, or tear the 
curtain.
The shutter curtain may appear to be unevenly colored, but this has no 
affect on pictures and does not indicate a malfunction. 
						

							454
Storage: To prevent mold or mildew, store the camera in a dry, well-
ventilated area. If you are using an AC adapter, unplug the adapter to 
prevent fire. If the product will not be used for an extended period, 
remove the battery to prevent leakage and store the camera in a plastic 
bag containing a desiccant.
 Do not, however, store the camera case in a 
plastic bag, as this may caus e the material to deteriorate. Note that 
desiccant gradually loses its capacity  to absorb moisture and should be 
replaced at regular intervals.
To prevent mold or mildew, take the camera out of storage at least once 
a month.
 Turn the camera on and release the shutter a few times before 
putting it away.
Store the battery in a cool, dry place.
 Replace the terminal cover before 
putting the battery away.
Turn the product off before removing or disconnecting the power source : Do not 
unplug the product or remove the ba ttery while the product is on or 
while images are being recorded or deleted.
 Forcibly cutting power in 
these circumstances could result in loss of data or in damage to product 
memory or internal circuitry.
 To prevent an accidental interruption of 
power, avoid carrying the product from one location to another while 
the AC adapter is connected. 
						

							455
Notes on the monitor: The monitor is constructed with extremely high 
p rec i s i o n ;  a t  l e a s t  9 9 .9 9 %  o f  p i xel s a re  e ffec t i ve,  w i t h  n o  m o re  t h a n  0 . 0 1 %  
being missing or defective.
 Hence while these displays may contain 
pixels that are always lit (white, red, blue, or green) or always off (black), 
this is not a malfunction and has no effect on images recorded with the 
device.
Images in the monitor may be difficult to see in a bright light.
Do not apply pressure to the monitor, as this could cause damage or 
malfunction.
 Dust or lint on the monitor can be removed with a blower. Stains can be removed by wiping lightly with a soft cloth or chamois 
leather. Should the monitor break, care should be taken to avoid injury 
from broken glass and to prevent  liquid crystal from the monitor 
touching the skin or entering the eyes and mouth.
Replace the monitor cover when transporting the camera or leaving it 
unattended.
The battery and charger : Batteries may leak or explode if improperly 
handled.
 Read and follow the warnings and cautions on pages xiii–xvi of 
this manual. Observe the following precautions when handling 
batteries:
• Use only batteries approved  for use in this equipment.
• Do not expose the battery to flame or excessive heat.
• Keep the battery terminals clean.
• Turn the product off before replacing the battery.
• Remove the battery from the camera or charger when not in use and 
replace the terminal cover.
 These devices draw minute amounts of 
charge even when off and could draw the battery down to the point 
that it will no longer function.
 If the battery will not be used for some 
time, insert it in the camera and run it flat before removing it from the 
camera for storage.
 The battery should be stored in a cool location 
with an ambient temperature of 15 °C to 25 °C (59 °F to 77 °F; avoid hot 
or extremely cold locations).
 Repeat this process at least once every six 
months.

•Turning the camera on or off repeatedly when the battery is fully 
discharged will shorten battery life. Batteries that have been fully 
discharged must be charged before use.
• The internal temperature of the battery may rise while the battery is in 
use.
 Attempting to charge the battery while the internal temperature 
is elevated will impair battery performance, and the battery may not 
charge or charge only partially.
 Wait for the battery to cool before 
charging.
• Charge the battery indoors at ambient temperatures of 5 °C–35 °C 
(41 °F–95 °F).
 Do not use the battery at ambient temperatures below 
0 °C (32 °F) or above 40 °C (104 °F); failure to observe this precaution 
could damage the battery or impair its performance.
 Capacity may be 
reduced and charging times increase  at battery temperatures from 0 °C 
(32 °F) to 15 °C (59 °F) and from 45 °C (113 °F) to 60 °C (140 °F).
 The 
battery will not charge if its temp erature is below 0 °C (32 °F) or above 
60 °C (140 °F).
• If the  CHARGE  lamp flashes quickly (about eight times a second) during 
charging, confirm that the temperature is in the correct range and then 
unplug the charger and remove and reinsert the battery.
 If the 
problem persists, cease use immediately and take battery and charger 
to your retailer or a Nikon-authorized service representative.
• Do not move the charger or touch the battery during charging.
 Failure 
to observe this precaution could in very rare instances result in the 
charger showing that charging is co mplete when the battery is only 
partially charged.
 Remove and reinsert the battery to begin charging 
again. Battery capacity may temporarily drop if the battery is charged 
at low temperatures or used at a temperature below the temperature 
at which it was charged.
 If the battery is charged at a temperature 
below 5 °C (41 °F), the battery life indicator in the  Battery info (0 374) 
display may show a temporary decrease.
