  • Page 5: Introduction

    Congratulations on the purchase of your new OTS Spectrum Full-Face Mask! This full-face mask (FFM) is one of the few that has been designed from the ground up as a scuba diving mask. The Spectrum FFM was designed with comfort, fit, and function in mind. Having been in the...

  • Page 6: Warnings And Precautions

    Diving is an inherently dangerous sport. Participating in this activity puts you at risk of serious injury or even death. • Prior to diving the Spectrum FFM, ensure it is clear of all packing materials or any other foreign debris.

  • Page 7: Description

    Physiological Considerations The Spectrum FFM protects the diver in other ways as well. If, for any reason, a diver were to become unconscious underwater, the Spectrum FFM is able to maintain a breathable airspace in front of the diver’s nose and mouth assisting in survival (assuming the scuba tank has air).

  • Page 8: Communications

    Communications In order to use underwater communications, an airspace is required to allow for articulation and placement of a microphone. The Spectrum FFM has an oral/nasal cavity that provides optimal communications, while some FFMs have the nose separated from the mouth. This separation alters the voice slightly, as in pinching your nose when talking and does not achieve optimal underwater communications.

    Visor Drain Holes Figure 3: Drain Tab The Spectrum features two Visor Drain Holes located in the inside of the mask on the top of the oral nasal pocket where the “teardrop” portion of the visor meet.

    Regulators Figure 11: Inner Frame Removal The regulator port of the Spectrum allows regulators from 3/16” x 5/8” and sizes up to 1-7/16” x 13/16”. NOTE : The regulator port can be safely stretched up to 50% to allow bigger sized mouthpiece tubes.

    ALWAYS inspect your diving equipment to ensure it is not damaged or defective and that it is fully functional. DO NOT dive the Spectrum FFM or any other equipment if you have not verified that it is in good condition and working properly! If this equipment has been damaged, tampered with, or found to be defective, return it to OTS or replace components immediately.

  • Page 14: Donning And Adjustment

    An improperly adjusted mask will result in jaw fatigue, increased air consumption, leaking, and an overall poor fit. First and foremost the Spectrum FFM must be fitted to the chin; the rest of the mask will seal to the face where it lays.

  • Page 15: Doffing

    Post-Dive Procedures After a diver has completed diving, remove the Spectrum FFM. Thoroughly rinse the Spectrum FFM in clear, fresh water and pat it dry with a lint-free absorbent cloth. If necessary, a mild detergent may be used for cleaning the Spectrum FFM.

  • Page 16: Warning Note

    Regardless of prior FFM diving experience, take some time to dive the Spectrum FFM in a pool or similar environment. Follow the guidelines in this manual and seek additional instruction if necessary. Learning how to dive the Spectrum FFM to a point that feels completely comfortable with all aspects is critical.

  • Page 17: Emergency Procedures

    Emergency Procedures First, know the location of the alternate air supply, then remove the Spectrum FFM. This is best done by grasping the bottom of the mask and placing the thumbs on the lower buckle tabs. Pull out on these tabs, loosening and rotating the mask forward and back over the head.

  • Page 18: Installation Of Communications

    Regardless of the system, the EM assembly mounts to the mask in the same manner. If the Spectrum FFM was purchased without communications equipment, there will be a blanking plug installed in the communications port. This consists of a plug on the inside (of the mask) secured with a threaded, locking ring on the outside (Figure 17).
