7-Inch Wireless Rearview Monitor for Car/Truck/RV/Bus — Touchscreen TV Display, Dual Camera Channels 2370 & 2510

Before use: switch off FM radio and any nearby electronic devices to reduce signal interference. To view the wireless camera, press the monitor’s 1st button or select AV2 using the remote’s Video Select. The system supports two camera channels: channel 2370 (includes reversing guide lines) and channel 2510 (no guide lines, for monitoring). Change between these channels by pressing the monitor’s 2nd button or using Model Select on the remote. For strongest reception, point the monitor and camera antennas toward each other. Maintain at least 2 meters (about 78.7") distance between the camera and monitor to prevent mutual interference. The IR-equipped camera provides night vision and its LEDs will glow red in low-light conditions.You may also like 7-Inch HD Car TFT LCD Mirror Monitor — 2-Channel AV Parking Screen for Rear-View Backup Camera, Touch + Remote.
