MAINTENANCE
Read This Section Before Use!
■
Operation in extremely low, ambient temperatures can
cause delays in LCD operation.
■
Always be sure to check the battery capacity before use.
■
Remove the battery whenever the instrument is not to be
used for an extended period of time.
■
When storing the instrument in areas subject to extremely
low temperatures, leave the carrying case open.
■
Do not overtighten any of the clamp screws.
■
When adjusting the vertical and horizontal tangent screws
or leveling screws, fix them as close as possible to the
center position, as indicated by the lines on the screws.
Always be sure to finish the tangential adjustment with a
clockwise rotation of the tangent screw.
■
If you do not intend to remove the leveling base from the
instrument for an extended period, lock the leveling base
clamp knob and tighten its safety screw.
■
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. Organic solvents will
discolor the surfaces or remove the printed characters.
Clean only with a soft cloth or tissue slightly moistened with
water or a mild detergent. Clean the carrying case in the
same way.
■
Clean the optical lenses by wiping lightly with a soft cloth or
tissue moistened with alcohol.
■
Do not leave the carrying case exposed to rain for an
extended period of time. If exposure to rain is unavoidable,
be sure to place the carrying case with the “Nikon”
nameplate facing upwards.
