PocketScope Retinoscope

PocketScope Otoscope

Retinoscope Features • External focusing sleeve allows for easy adjustment regardless of what size hand or how instrument is held. Continuous 360˚ rotation. • Dust-free optics to keep instrument clean longer. • Fixation cards that easily attach for use during dynamic retinoscopy. • Collapsible head for compact size.

Throat Illuminator (21111 only) To convert otoscope to throat illuminator, unscrew otoscope head in counterclockwise direction. NOTE: Illuminator section can become hot. Avoid more than momentary direct skin contact. To turn instruments on and off, and vary intensity rotate switch at base of instrument head. As intensity increases, green band gets thicker.

Patents: US 5,189,449 and 5,459,535

NOTE: The retinoscope must be telescoped out by pulling in an outward direction. The retinoscope can only be used if this operation is performed. Practitioner Side

PocketScope Ophthalmoscope 1. Rubber Brow Rest. 2. Aperture selection dial with continuous rotation: Allows access to microspot, small, large, fixation, slit and cobalt blue. 3. Lens Selection Dial - When used with multiplier lever, allows single diopter steps through 48 lens combinations (from +22 to –25 diopters). 4. Multiplier Lever - Allows fast movement through the range via 16 diopter shifts. When used with lens selection dial, allows single diopter steps through 48 lens combinations. 5. Two-position filter switch: Engage either open or red-free filter. 6. Larger spot size for wider field of view. 7. Sealed optics. 8. Diopter Display Window - Displays direct reading of diopter values (positive values displayed in green; negative values displayed in red).

To move through the range on the negative (–) side: Rotate lens selection dial in negative (counterclockwise) direction. At –9 diopters move lens dial counterclockwise again. Then move multiplier lever to “–” position. Continue moving lens dial in same counterclockwise direction to access –10 to –25 diopters. Practitioner Side Rubber brow rest Lens selection dial

PocketScope Transilluminator Transilluminator Features • Fiber Optic transmission for bright cool light transmission. • Curved design to fit into tight areas. Transilluminator Attachment Remove the retinoscope by turning the instrument in a counterclockwise direction. This will disconnect the retinoscope. Connect the transilluminator by turning the instrument in a clockwise direction. Light pipe can be rotated to locate optimum orientation.

Lamp Replacement Retinoscope Lamp Replacement 1. Remove (unscrew) retinoscope head. 2. Grasp end of lamp and pull out (use nail file or similar object if necessary). 3. Insert replacement lamp by carefully aligning pin on lamp shaft with slot in retinoscope. Push lamp in until firmly seated.

Otoscope Lamp Replacement (21111 only) 1. Remove (unscrew) otoscope head. 2. Unscrew lamp holder in counterclockwise direction and remove from handle. 3. Grasp end of lamp and pull out of holder. 4. Insert new lamp by reversing above process. NOTE: If lamp surface is touched or becomes smudged, wipe clean with a soft cloth. This will assure longer lamp life and higher output.

Ophthalmoscope Lamp Replacement 1. Unscrew ophthalmoscope head in counterclockwise direction. 2. Grasp end of lamp and pull out (use nail file or similar object if necessary). 3. Insert replacement lamp by carefully aligning pin on lamp shaft with slot in ophthalmoscope head. Push lamp in until firmly seated. NOTE: If lamp surface is touched or becomes smudged, wipe clean with a soft cloth. This will assure longer lamp life and higher output.

Transilluminator Lamp Replacement 1. Place thumb on knurled ring at base of instrument. Unscrew transilluminator in a counterclockwise direction. 2. Grasp end of lamp and pull out (use nail file or similar object if needed). 3. Insert replacement lamp (No. 03400). Push lamp in firmly.

3. Locate and level prepared back panel within 6 feet of an electrical outlet. 4. Mark the location of the two holes and drill holes to suit anchors provided: Hard materials (concrete) require larger holes (1/2 inch). Soft materials (plaster board) require smaller holes (3/16 inch). 5. Set anchors flush with the wall surface. Solid wood walls require no anchor. Thin panel walls require an anchor designed specifically for these materials. 6. Attach back panel to wall. Slide charger down in place until unit snaps into final locked position. 7. Plug transformer into outlet. CAUTION: NOT FOR USE IN THE PRESENCE OF FLAMMABLE ANESTHETICS.

Desk/Wall Charger Installation For Desk 1. Select a smooth level surface within 6 feet of a grounded electrical outlet. 2. Plug transformer into outlet. For Wall 1. Turn charger upside down. Push back panel out slightly; then slide upward from charger base. 2. Punch or drill out two round knockouts. Panel may now be used as template. 14
