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.
