Basic Care
1. The vision screener is a precision instrument. DO NOT drop it or subject it to physical shock.
2. The vision screener is NOT waterproof. If you accidentally drop it into liquid or liquid is spilled on the
device, contact Welch Allyn Support immediately. If minor water droplets are found on the device, wipe
off with a soft dry cloth.
3. DO NOT leave the vision screener in excessive heat, such as in a car or in direct sunlight. High
temperatures can cause the device to malfunction.
4. The vision screener contains precision electronic circuitry. Never attempt to disassemble the vision
screener; this may result in bodily harm and will void any warranty.
5. DO NOT use cleaners that contain organic solvents to clean the vision screener’s body or the front glass.
Instead, use the provided cleaning cloth and for stubborn stains use with a small amount of water or a
non-abrasive cleaner. Always keep the front glass free of fingerprints, dirt and dust.
6. When plugging the AC power connector into The vision screener, DO NOT force the power connector into
the device as this may cause damage and will not be covered under warranty.
7. DO NOT store the vision screener in its case with the power cord plugged in, this could cause damage to
both the power cord and the device. If plugged in, store in a location with no interference with the
power cord.
8. DO NOT use the wrist strap as a means to carry the device; it is not designed to carry the weight of the
vision screener.

acceptable for use with the device.
