* Waterproof models
The PROSTAFF 3 is waterproof, and will suffer no damage to the optical system if submerged or dropped in water to a
maximum depth of 1 meter for up to 10 minutes.
The PROSTAFF 3 offers the following advantages:
• Can be used in conditions of high humidity, dust and rain without risk of damage.
• Nitrogen-filled design makes it resistant to condensation and mold.
Observe the following when using the PROSTAFF 3:
• The unit should not be operated nor held in running water.
• Any moisture should be wiped off before adjusting movable parts (focusing knob, eyepiece, etc.) of the PROSTAFF 3 to
prevent damage and for safety reasons.
To keep your PROSTAFF 3 in excellent condition, Nikon Vision recommends regular servicing by an authorized dealer.
** The battery chamber is water resistant, not waterproof. Water may enter the device if the PROSTAFF 3 is submerged in
water. If water enters the battery chamber, wipe out any moisture and allow time for the chamber to dry.
