Diagnostic Instruments
• When connecting instrument heads to handles please check
that the voltage of the bulb in the instrument corresponds
with the voltage of the handle
• Care should be taken when fitting heads to handles not to
trap skin between parts
• Please ensure that the control is in the off position when the
examination has been completed
• Keeler Professional Retinoscopes contain strong magnets.
Pacemakers and magnetically stored data will be affected or
damaged by magnets
• Strong magnetic fields may influence or distort sensitive
electronic or mechanical test instruments. Very sensitive
devices may even be destroyed. Always keep magnets at a
safe distance from such devices
• Do not use Keeler Retinoscopes in ambient temperatures
above 30°C
• Disposable speculae should not be used for insufflation
testing
• Plastic reusable Speculae will degrade if exposed to ultra-
violet light, dry heat or gamma irradiation. These methods of
sterilization must not be used
• This device must only be used by clinicians trained in the use
of ophthalmic devices

area with soap and water. If it contacts the eye, seek medical
attention immediately
• Ensure battery orientation is correct, or personal injury /
damage to equipment may occur
• Do not mix battery types
• Do not attempt to charge Non-Rechargeable batteries
• Do not charge battery in an environment
where the temperature may exceed
40˚C or fall below 0˚C
