WARNING AND CAUTION
Read This Section Before Use!
WARNING
Never see the sun through the telescope. Doing so may cause
the loss of your eyesight.
The DTM-350/330 does not feature explosion-protected
construction. Do not use in coal mines, in areas contaminated
with coal dust, or near other flammable substances.
Never disassemble, modify or repair the instrument. Doing so
may cause fire, electric shock or burn.
Use only the specified charger Q-75U/E for charging the battery
pack BC-65. Charging by the other types of chargers than
specified may cause fire or rupture. (BC-65 can not be charged
by using the charger Q-7U/E or Q7C.)
While recharging the battery pack, do not cover the charger with
any blanket or clothing which can cause overheating. Make sure
the charger is able to dissipate heat adequately. Especially, do not
block its air holes while recharging. If so, the gas will remain in the
battery pack and may cause rupture.
Avoid recharging in humid or dusty places, in direct sunlight, and
near heaters. Do not recharge when wet. Doing so may cause
electric shock, overheating or fire.
Although the battery pack BC-65 is equipped with an auto-reset
circuit breaker, care should be taken not to short the contacts.
Shorting may cause fire or burn.
Never burn or heat the battery. Doing so may cause rupture or
injury.
When storing the battery pack or charger, guard against a short
circuit by putting the insulating tape on the contact point or by
doing some other methods. Failure to do so may result in a short
circuit, causing a fire, burn or instrument damage.
The battery BC-65 is not designed to be waterproof by itself. Do
not wet the battery with removed from the instrument. Doing so
may cause fire or burn.

WARNING AND CAUTION
Read This Section Before Use!
CAUTION
The top of the tripod ferrule is very sharp and may injure your
body. Be careful in handling or carrying the tripod.
Check the shoulder strap and its clasp before carrying the tripod
or the instrument encased in the carrying case. Damaged strap or
imperfect clasping may cause an accident of falling.
Before setting up the tripod, check below to make sure no one’s
hands or feet are in the way. Failure to do so may result in injury if
hands or feet should be pierced by the legs of the tripod.
Fasten firmly the thumb screws of the tripod legs after mounting
the instrument on the tripod. If not, the tripod may collapse,
resulting in injury or instrument damage.
Be sure to fasten the clamp screw on the tripod securely after
installing the instrument on the tripod. Failure to do this may
cause the instrument to fall, resulting in injury or instrument
damage.
Fasten securely the leveling base clamp knob. If the knob is not
securely fastened, the leveling base may fall when you grasp the
carrying handle, resulting in injury or instrument damage.
Do not stack up the plastic carrying case and do not use it as a
stool. Plastic carrying case is slippery and unstable. Doing things
like this may cause an accident and result in personal injury or
instrument damage.
Do not swing or throw the plumb bob. It may hit and injure the
other person.
Be sure to read the instructions of Quick Charger Q-75U/E before
starting charging operation.

MAINTENANCE
Read This Section Before Use!
Avoid prolonged exposure to the sun or the heat of a closed
vehicle. Efficiency could be adversely affected.
If the instrument has been used in wet conditions, incline the
instrument so as to remove the water drops out of the concave
parts on the instrument. Wipe off any moisture on the instrument
and dry it completely before replacing it in its carrying case. The
instrument contains many sensitive electronic assemblies which
have been well protected against dust and moisture. However,
should dust or moisture be introduced into the instrument, severe
damage could result.
Sudden changes in temperature may cloud the lenses and
drastically reduce the measurable distance, or initiate an electrical
system failure. Should this occur, leave the instrument in a warm
location with the case closed until the temperature of the
instrument returns to room temperature.
Avoid storing the instrument in hot humid locations. Especially, the
battery pack should be stored in a dry location at a temperature of
less than 30°C. Higher temperature and excessive humidity may
result in growth of mold on the lenses and deterioration of the
electronic assemblies, leading to instrument failure.
Store the battery pack with the battery discharged.
When storing the instrument in areas subject to extremely low
temperature, leave the carrying case open.
Do not overtighten any of the clamp screws.
When adjusting the vertical and upper plate tangent screws or the
leveling screws, stay as close as possible to the center of the
screw’s range, as indicated by a line on the screw.
Use a clockwise rotation of the tangent screws for final
adjustment.
If the leveling base is to be left unused for an extended period,
lock-down the leveling base clamp knob and tighten its safety
screw.
v
MAINTENANCE
Read This Section Before Use!
Do not use organic solvents (such as ether or paint thinner) to
clean the non-metallic parts such as the keyboard, and the
painted or printed surfaces. Doing so could result in discoloration
or in the peeling of printed characters. Clean only with a soft cloth
or tissue lightly moistened with water or mild detergent.
Optical lenses may be cleaned by lightly wiping them with a soft
cloth or lens tissue moistened with alcohol.
Do not release the reticle plate
cover, and do not subject it to
undue force, as this cover has
been appropriately mounted.
Doing so could adversely affect
the watertight structure of the
unit.
Before attaching the battery pack, first make sure that the surface
where the battery pack attaches is clear of foreign matter, and
then press the battery pack into place until the battery mounting
button rises up to the battery pack top surface. If the battery pack
is not attached securely, it could adversely affect the watertight
structure of the unit.
Press the cap for data output/external power input connector until
it clicks into place. If this cap is not attached securely, it could
adversely affect the watertight structure of the unit.
Do not leave the carrying case exposed to rain for an extended
period of time, though it is designed to be watertight. If you
expose the carrying case to rain because of unavoidable
circumstances, place it with its “Nikon” nameplate upward.
The BC-65 battery pack holds Ni-MH inside. Be sure to follow the
laws or rules of your municipal waste system when disposing of it.
