For the included remote control, the following is required:
•
The projector and the remote shall be designed together to have a 40 feet range from the front of the
projector and a 20 feet range from the top.
•
The dispersion angle from the IR emitter(s) shall be at least 15 degrees.
•
There are 2 independent sets of NEC HEX codes with identical control (identified as Code 1 and
Code 2 in Table ).
•
The method to switch the remote to the other code set is to hold down the "Address" and
"Enter" keys simultaneously for 5 seconds. While these two keys are pressed there will be
no IR transmission. When the code set has changed the remote will blink the
back-lighting once as a visual confirmation of the change.
•
The buttons are to be back-lighted with red (625-670nm) LEDs. The back-lighting will turn on
after any key press. The back-lighting will turn off during IR transmission as feedback that a key is
being pressed and that transmission is occurring. The backlighting will stay on for 10 seconds after
any key is pressed or until the "Address" button is pressed again. Key icons and text must be
clearly visible from 2 feet away when the back-lighting is on in a dark room.
•
The key trip force shall be 135 +/- 35 grams
•
2 AA batteries to be used. The lifetime of the remote should be approximately 6 months under
normal use conditions with alkaline batteries.
•
The remote control button layout is shown in Figure 1.
