Nikon SB-50DX - Manual (Page 33)

65 64
Nikon cannot be held responsible for any malfunction resulting from the use of
the camera other than as specified in this manual.
• Use two CR123A or DL123A type lithium batteries
Use two fresh CR123A or DL123A type lithium batteries. Do not mix different
types of batteries.
• Change the batteries well before the end of their life and prepare spare batteries
before important photographic occasions.
• Turn the SB-50DX’s power off when changing batteries
Turn the SB-50DX’s power off before changing batteries and insert the batteries
with ´ and ‰ ends positioned correctly.
• Stains on the battery poles may cause lack of contact. Wipe the batteries well
with a dry cloth before installing.
• Use fresh batteries at low temperatures
Battery power diminishes at extremely low temperatures and the SB-50DX may
not function properly with old batteries. Use a fresh set of batteries at low
temperatures, keep spare batteries warm, and use them alternately.
• Flash recycling time slows down and number of firings per set of batteries
becomes less at low temperatures. However, battery power usually recovers
when the temperature returns to normal.
• Do not throw batteries into a fire or short circuit batteries
Do not throw batteries into a fire. Do not short, disassemble, heat or charge
batteries.
WARNING
Do not leave
Keep batteries out of children’s
reach.
If someone accidentally swallows batteries,
call a doctor immediately.
Notes on Batteries
Miscellaneous
• Cleaning Speedlight
Use a blower brush to remove dirt and dust from the SB-50DX and clean it with a
soft, clean cloth. After using the SB-50DX near seawater, wipe the SB-50DX with
a soft, clean cloth slightly moistened with pure water to remove salt, and then dry
it with a dry cloth. NEVER use organic solvents like thinner or benzene. They
may damage the SB-50DX.
On rare occasions, the LCD may turn on or turn dark due to static electricity. This
is not a malfunction. The display soon returns to normal.
• Do not subject the SB-50DX to strong vibration or shock
Do not drop the SB-50DX or hit it against a hard surface as this may damage its
precision mechanism.
• Avoid strong electric or magnetic fields
The SB-50DX may not function properly in strong electric or magnetic fields such
as near a transmitter tower. Avoid using the SB-50DX in such locations.
• Store the SB-50DX in a cool, dry place
Store the SB-50DX in a cool, dry place to prevent mold and mildew.
Keep it away from naphthalene or camphor (moth repellent), electrical appliances
that generate magnetic fields or an excessively hot place such as inside a vehicle
during the summer or near a heater.
• Avoid extreme temperature change
An extreme temperature change can cause condensation inside the SB-50DX.
When taking the SB-50DX to a very hot place from a very cold place or vice
versa, place it inside an airtight container such as a plastic bag and leave it inside
a while to expose the SB-50DX gradually to the temperature change.
• Avoid water or moisture
Keep the SB-50DX away from water or moisture. When using the SB-50DX near
water, guard against splashes, especially salt water spray.
• Remove the batteries and store the SB-50DX with a desiccant
If you do not intend to use the SB-50DX for a long time, remove the batteries to
protect the SB-50DX from battery leakage.
• In a humid environment, store the SB-50DX inside a plastic bag with a
desiccant to keep out dust, moisture and salt. Note, however, that storing
leather cases in vinyl bags may cause the leather to deteriorate. Keep the
batteries in a cool, dry place away from heat or humidity.
• Change the desiccant occasionally since it does not absorb moisture effectively
after a while.
• Leaving the SB-50DX unused for a long period of time may cause mold to grow
and result in malfunction. To maintain the Speedlight in peak condition, fire it a
few times every month. This will enable you to use the flash for many years.
