-6-E.Pairing the digital wireless camera and receiversWhen you get the digital wireless cameras or receiver, you must pair them before use it, following the instructions as below:1.Power on the digital wireless camera and receiver by inserting the power adaptor jack.2.Press the PAIR/CH or PAIR button of receivers and not release until the power LED begin to flash, and the monitor will reveal the picture as below, then release the PAIR/CH button.3.Press the PAIR button of digital wireless camera once within 30 seconds . They will automatically link to each other by ID code after pairing finished.4.Please don't turn off their power during the paring status.5.When pairing successfully, the power LED for both will be lit directly (not flash) Pairing buttonPairing button
-7-F.:Operations1.Multiple receiver：long press PAIR/CH button will get into paring mode as E; press PAIR/CH button shortly to switch the display as CAM1 → CAM2 → CAM3 → CAM4 → Quad mode → CAM1…… sequentially by each pressing.2.Single receiver：long press PAIR button will get into paring mode as E; press PAIR button shortly to switch OSD on/off.3.Multiple receiver：long press MODE button to get into SCAN mode, it will display CAM1 → CAM2 → CAM3 → CAM4 → CAM1…… automatically every 5 seconds, and press PAIR/CH button to stop; press MODE button shortly to switch OSD on/off.4. Multiple receiver：long press PAIR/CH and MODE buttons until show up“Erase All Pairing Data” , it will clear the pairing content ,so that it would be quick when you repairG.Use Notes1.Be sure the digital wireless camera and the receiver were connected to the equipment correctly (e.g. Connect the digital wireless camera, and the receiver to the TV or DVR).2.When DC plug is pulled out from digital wireless camera or receiver, it needs to wait for a few seconds to insert it again.3.Adjust antenna to decrease interference. (vertical or horizontal)4.In most situations, one pair has a better distance up to 150 meter(open site and line of sight). When two pairs or more are used at the same time, it can automatically jump to different channels. But the distance between pairs, preferably greater than 2 meter far.5.If there are some reasons cause the devise stop, you can try to pull out and insert the power plug again and make the devise re-link.6.It is suggested to have 10 pairs mostly operated in same location, but the pairing can not be at the same time.
-8-Problems Possible SolutionMonitor(RX) shows TX power off; TX/RX distance is too long, so that transmission“No Signal” signal is weak, please check and make it right Check all cable connections Make sure power plugs are pushed all the way in No picture Check if the POWER LED of the digital wireless camera and receiver is lighting or not? Their LINK LED should be lit If Their LINK LED should not be lit, you must re-pair their codes following the E. instruction of the manual Adjust receiver and digital wireless camera antenna orientation Try to place digital wireless camera and receiver in a more close-in Interference location If using a microwave oven, turn it off. Remove microwave oven or wireless router from the path between digital wireless camera and receiverH.TroubleshootingMulti Receiver:Operating Frequency Band 2.403GHz~2.478GHzReceiver Sensitivity -85dBm min.Video Output Level 1±0.2V p-p ＠ 75 ohmModulation GMSKAntenna Omni-directionalPower consumption 1.0WPower supply 5V/1.2A or 12V/0.5ADimension 100mm*87mm*30mmWeight 120gSingle Receiver:Operating Frequency Band 2.403GHz~2.478GHzI.Specifications
