DO NOT CUT OR SPLICE THE CAMERA’S CABLE. MODIFYING THE UNIT IN ANY WAY WILL VOID THE WARRANTY.
Installation Procedures:
1. Remove the Housing Cap from the camera 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 chan-
nel 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 modulated source.
When combining with cable service, be aware that digital data typically interferes with channels 80-117, even when
not subscribed to digital services. Channels 120-125 often work without any filtering.
2. Ensure that the camera is grounded with the ground strap as shown in the FCC Information. Connect a coax cable from
the camera’s 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. Connect the 12V DC 300mA power supply to an AC outlet and
the Power Injector. The camera picture is now available on the programmed TV channel.
3. Mount the base to the junction box (not included) and adjust the camera assembly for proper viewing. When satisfied,
secure all adjustment points.
