/V 1- In place of ©, specify lens color code from table on the right. 2- A replaceable LED lamp is included with the operator.
3. Because the LED lamp does not contain an internal current limiting resistor, an external resistor must be added. For recommended values, see table below.
4. For accessories, see page 449.
5. For dimensions, see page 450.
