OrientingAntennas for Optimal Performance 8
The Wireless Baby Guard Broadcasts its high-quality
audio and video using directional antennas which
mush be oriented in certain configurations for best
results. The 2.4 GHz audio/video antennas have been
designed to pivot and have limited rotation in either
clockwise or counter clockwise directions.
Warning：See instructions shown below for rotating
antennas. Rotation antennas beyond the specified
range will result in permanent damage to both
antennas and the mechanical stopper. Antenna does
not rotate over 270 degrees.
Maximum rotation of audio/video Rear View Front View
Antenna shown.
In most situations, the flat pitted face of the A/V
antennas on both the transmitter and receiver should be
facing one another. Since all rooms are different, for
optimal reception, additional slight pivots or rotations
may be necessary. If the transmitter and receiver are less
than 10 feet apart, keep the A/V antennas flat in their
casings.
