• The UV timer can be set from 0 to 30 min. The default setting is for 5 min. When the UV timer is set to
zero, the UV lamp will not light.
• If the outer door is opened while the UV lamp is lit, the lamp will turn OFF. Then, when the door is
closed, the lamp will light for the preset period of time.
• If the UV lamp ON time is set for longer than 10 minutes or if only the outer door is repeated opened
and closed, condensation may occur in the chamber and may affect temperature distribution. It will also
shorten the service life of the UV lamp.
• When replacing the UV lamp, consult with a Sanyo representative or agent.
Note: To compensate for the drop in UV ray output along with increased accumulated ON time of UV
lamp, the Incubator automatically extends the UV lamp ON time according to the accumulated ON time.
The automatically extended time is displayed as a percentage under UV Timer Ext. in the UV Setting
Screen.
