Remote Control Operation
Point the remote control to the infrared remote sensor and press a key.
Notes:
• The remote control may not operate when there is sunlight or other strong light such as a fluorescent lamp
shining on the remote sensor.
• Remove the batteries from the remote control once they have run out and change two new batteries. Do
not mix new and old batteries, or batteries of different types. This may shorten the life on batteries or may
cause old batteries to leak.
