Contents Introduction The AP250 is used for measuring visual acuity.
Introduction Congratulations on your purchase of the AP250 Automated Projector. Safety Precautions Except for changing the Halogen bulb and replacing the fuses, any repair or service on the AP250 must be performed only by authorized Reichert Ophthalmic Instruments personnel. Only qualified and trained personnel should operate the AP250. Training for operating personnel is the sole responsibility of the owner. Plug the AP250 only into a grounded electrical receptacle.

Installation The AP250 should be installed according to the following procedures: 1. If using a wall mount, it is best to locate a wall stud to support the projectors weight. 2. The following distances are important in the set-up of a refracting room: 4. Install the projector screen. 6. If attaching the AP250 to a mount, loosen the mounting screw (see "Instrument Components," p. 3, #8) and insert the projector mount onto the ball.
Alignment You can choose an optimum projection distance when patient and projector are equally away from the projection screen. Images can be optimally focused at projection distances between 10 ft. (3 m ) and 26.5 ft. (8 m ). 1. Project a 20/200 or 0.1 "Z" (or other characters) onto the screen by pressing the key. 2. Check the three dimensional alignment of the system. The projector is optimized when the projection screen is angled to direct light to the patients head. Place a mirror on the screen.
Instructions for Use - Remote Control The AP250 is operated by a sophisticated remote control that is divided into various sections for ease of use (see Figure 6, below). To change the code, follow the steps below: 1. Open the battery compartment on the rear side of the remote control (see Figure 7, p. 7). Select a new combination of switch settings by moving the switches (with a small pointed object). Sixteen combinations are possible. 2. Turn the projector off.

Interrupting a Slide Sequence at a Defined Point 1. Press the Program Key (1 or 2) you want to interrupt. 2. Press the IN Program Key. 3. Press the NEXT Program Key until the slide appears that you want to conclude the sequence. 4. Press the OUT Program Key. The new slide sequence is now stored.
Care and Maintenance WARNING: Risk of electric shock. Always disconnect the power cord from the wall and the instrument before performing any of the following care and maintenance procedures. CAUTION: Observe polarization markings on the inside of the battery compartment and insert batteries accordingly. CHANGING FUSES WARNING: Risk of electric shock. Always disconnect the power before changing fuses. CHANGING THE HALOGEN BULB WARNING: Do not touch the Halogen Bulb if the unit has been in use.
