Page 8: Handles
Handles Two sets of handles are provided to facilitate operation of the submerged unit in either a horizontal or a vertical orientation. The handles are held in place with stainless socket head cap screws. On the right-hand side handle, a waterproof pushbutton switch, operated by the diver’s thumb, has been incorporated to acquire spectral scans when the instrument is located vertically, with the optical port at the bottom. -
Page 9: Controls
Controls When the instrument is installed within the Underwater Housing, the touch-screen controls are accessed via a set of specially-designed, sealed actuator pins (aka plungers), using a design which has been well-proven in the field. These plungers are incorporated into the rear acrylic panel (shown in Figure 5). The plungers are used by the diver to operate the menus on the LCD panel on the rear of the instrument. -

Page 19: Special Note - Enclosure Leak Check
SPECIAL NOTE – Enclosure Leak Check While each housing has been water tested for leaks prior to shipment, it is strongly recommended (owing to the cost of the Spectroradiometer) that the empty housing be “bounce dived” to the maximum expected working depth prior to the unit’s first use after shipping or after storage for any extended period. -

Figure 19 Using Jackscrews To Extract Rear Panel The Rear Panel supports the use of four nylon jackscrews (P/N HDW001409) as an aid to extracting the Rear Panel / Instrument assembly from the enclosure (See Figure 19). After releasing all four latches, insert the four jackscrews as shown, hand-tightening each until they all bottom out against the rear face of the enclosure opening. -
Page 22: Ballast Weights
Ballast Weights Standard dive weights may be used to provide any necessary ballast. The weights may be secured to the black skids located on the bottom of the housing, using standard cable ties. It is recommended that the unit be set up to be very slightly negative to allow for easy underwater maneuvering. -
