Operating range is 250’ (76M) open distance.
Each time the RF signal penetrates a wall,
distance will fall off 50%.
If you encounter any difficulties installing or servicing
your LVC-IV, call your dealer or contact Draper, Inc.

To "Learn" a remote
1.
Press receiver button on LVC-IV (see Fig. 2A).
2.
Signal light will flash slowly.
3.
Press
4.
Signal light flashes three times quickly.
(UP) on transmitter within 10 seconds (see Fig. 2B).
To "Un-Learn" a remote
1.
Press receiver button on LVC-IV (see Fig. 2A).
2.
Signal light will flash slowly.
3.
Press
4.
Signal light flashes three times quickly.
(DOWN) on transmitter within 10 seconds (see Fig. 2C).
To "Un-Learn" all remotes
1.
Press receiver button on LVC-IV until signal light flashes quickly,
then release.
2.
Press receiver button once while signal light is flashing.
3.
Signal light will stop flashing.
Please Note: Operating range is 250ft (76 meters) open distance.
RF Signal will degrade significantly with each wall
it is required to penetrate.
If you are experiencing issues with RF signal
strength, the RF antenna can be threaded out
one of the knockouts for better reception.

PLEASE NOTE:
1. RF receiver MUST NOT TOUCH METAL OBJECTS!
Maximum Distance of Transmitter will be affected negatively.
2. Disconnect the power supply before installing the RF receiver.
3. Avoid electrostatic interference:
Static electricity will damage the electronic components.
4. Ensure there is > 5' (1.52M) between RF receiver and ground.
5. Ensure there is > 1' (30.5cm) between RF receiver and ceiling.
6. Ensure there is > 1' (30.5cm) between RF receiver and transmitter.
7. Multiple receivers must be spaced > 8" (20cm) apart.
Section 3 - Infrared (IR) Remote Control
1.
Plug Optional IR Eye into mini plug input provided on LVC-IV (see Figs. 1 and 3).
2.
IR Remote Control transmitter does not need to be "learned" by the LVC-IV. Simply point and operate.
3.
Maximum IR Eye cable length is 42" (1 meter).
Please Note: IR Transmitter Range is 26ft. (7.9 meters).

Section 4 - DC Low-voltage Trigger
The LVC-IV comes with built-in connection for sending a DC trigger (4-2 8 VDC) from the projector to the projection screen.
1.
Connect remote trigger voltage from projector to the low-voltage trigger cable.
2.
Plug the mini-jack plug of the low-voltage trigger cable to the LVC-IV (Figure 4).
3.
When projector is 'ON' the low-voltage output of the projector will cause LVC-IV to
deploy projection screen. When projector 'OFF' the low-voltage is removed from
LVC-IV and projection screen will retract into case.
