RM70-W
Installation Procedures:
1. Remove the End Plate from the modulator assembly and set the channel with the switches as shown in Figure 1.
Choose an unused channel that matches the tuning mode of the televisions. With antenna tuning, choose a UHF
channel from 14-69. With cable tuning, choose a CABLE channel from 70-94 or 100-125. There must be at least one
blank channel on either side of the modulated channel to separate it from any other broadcast, cable, or modu-
lated source. When combining with cable service, be aware that digital data typically interferes with channels
80-117, even when not subscribed to digital services. If no channels are available then a filter such as NetMedia's
CNF7080 (ch. 70-80) may be necessary.
2. Connect a coax cable from the modulator's Video/Power F-Connector to the "MOD" side of the Power Injector.
Connect the "TV" side of the Power Injector to the grounded coax from a television or distribution system. If also
providing power for a 12V DC camera, connect the Power Output Cable from the modulator's Power Output
connector to the camera; use a power supply that provides enough current for both devices. Connect the 12V DC
power supply to an AC outlet and the Power Injector.
3. Connect A/V sources to Audio and Video Inputs. Check modulator picture on the programmed TV channel. When
satisfied, fasten Base Plate to single gang junction box.
