Usage

Ensure the otoscope is switched off and disconnected from its power source (e.g. remove the handle from the charger or remove batteries) before replacing the bulb.
Allow the existing bulb to cool if it has been in recent use, as it may be hot.
Remove the otoscope head from the handle according to the instrument’s instructions.
Access the lamp compartment on the otoscope head (usually by unscrewing or pulling out the existing lamp from its socket).
Carefully remove the old bulb, avoiding excessive force that could damage the socket.
Handle the new bulb with clean, dry hands; avoid touching the glass envelope with bare fingers where possible to minimise oils on the surface.
Insert the new bulb firmly into the lamp socket, ensuring correct alignment and full seating as per Welch Allyn’s instructions.
Reassemble the otoscope head onto the handle and turn the instrument on to confirm that the new bulb illuminates correctly.
Dispose of the old bulb according to local regulations for small electrical and electronic components.
