High Temperature Nose; Power Supply - RayTek Raynger Series 3i Plus Operating Instructions Manual

5.4 High Temperature Nose

The instrument has a specially designed nose with high temperature resistant plastic material to avoid
damage from high temperature targets. On the other hand, please avoid over exposure when aiming

temperature of the nose. If it is too hot, there will be a warning on the LCD display (ambient highlight
display and backlight change to red plus audible buzzer). Please move the unit away from the high-
temperature target when seeing this alarm.
