Poor picture quality.
- The projector uses wireless LAN and Bluetooth communication, therefore the communication range may become short depending on the environment such as an obstruction between the projector and Wireless unit (or your smartphone), signal strength, and wall material. In such a case, change the projector’s location, or bring your device and the projector nearer to each other.
- If the projector is used near another device which uses wireless LAN or Bluetooth communication, interference may occur causing low communication speed or connection failure. In such a case, move the projector away from the other radio device. If the problem persists, turn off the other radio device.
The antenna is incorporated around
