6.3. When signal reception is unstable
Unstable signal reception may be caused by the placement, such as
position, height and angle of TX and RX or the operating environment.
When TX and RX are placed too close to each other, the transmission signal
may become too strong and may disturb the video signal. Please set the
POWER MODE switch on the TX to LOW position when the distance
between TX and RX is 3m or less.
6.4. Power back-up function
When operating the system by using external EXT DC, a power failure can
be prevented by mounting ENDURA battery on TX and/or RX
simultaneously. This function enables for continuous operation of the
system even when an accidental EXT DC power failure occurs.
6.5. Power through feature
The power switch located on the CW-7 will be turned ON and OFF of the
CW-7 and this ON/OFF switch will not affect the supplying of power to the
other devices. This feature is available on both the battery and EXT DC
operation.
