Operating Controls

The following multi-switch arrays are available to achieve the four roller movement functions:

• HK-4 Short-throw Joystick with mounting hardware suitable for hand, foot, or chin actuation.
• SB-4 Sip-and-Puff Control with mounting hardware requires two levels of intensity (mild and moderate) for both sipping and puffing to actuate the four roller functions.
• FK-4F Pedal Control requires minimum deflection of individual pedals.
• FK-4H Push-button Control has four individual recesses of 3/4" (19 mm) diameter for finger or pointer apparatus selection.
• CM-50-A Slot Control with Call Signal has five rugged, deeply recessed tread switches (four for roller movement and one for the call signal) suitable for persons having gross hand or foot movement which requires the deeper recesses for stabilization.

SCANNING - Single Switch Use

The SC-1 Scanning Controller is provided with adhesive-backed Velcro® strips for mounting it to the center of the upper housing of the Page Turner as shown. Retaining clips are provided to dress connecting cables neatly away from the box to the side of the Page Turner.

The Sc-1 Scanning Controller allows single-switch users to access this valuable device. Profoundly handicapped users relate to the four-position roller movement by watching the Scanner. When the LED (Light Emitting Diode) corresponding to the desired roller function illuminates, the user actuates an appropriate single switch to initiate the function.

For more information on switches, adaptive fixtures, and mounting systems, see Tools of the Trade.

The SC-1 has two modes of operation determined by a pushbutton at the side of the unit.

MOMENTARY Mode:
In this mode the user must maintain switch closure for the duration of the roller function. On release, the roller stops and LED scanning resumes. A fifth LED allows the user to turn the Scanner off when not in use.

Auto-Standby: Scanning will cease automatically after about two minutes of switch inactivity. The next switch activation will reinstate the scan.

LATCHING Mode:
For persons who are motorically less able, this mode allows one switch activation to start the roller function and a second switch activation to stop it. The first switch action "locks in" roller movement which continues until the second actuation stops it.

Special Considerations		Maintenance
The GEWA BLV-6 comfortably accommodates materials up to 2" (50mm) in spine thickness. Securing some of the pages under the inner plastic panels will allow some thicker books to be handled in sections. We suggest that the most cost-effective solution to accessing thicker reference texts, directories, epic sagas, bibles, etc., is to have them rebound into thinner volumes.		The rubber roller should be cleaned at about every 1,000 pages or whenever it appears shiny. Cleaning will remove the ink and paper residue which, over time, reduces the friction needed to grip pages properly. Reasonable cleaning agents include alcohol swaps, turpentine, and commercially available spray cleaners. IMPORTANT: Do NOT use solvents that may adversely attack the plastic panels.
