Notes
•
The unit cannot transmit in setting mode.
•
Make sure that the channel selected is the same as that
selected on the tuner used in the same system.
•
Depending on the noise or interference conditions, the
selectable channels may not necessarily all be usable. If
necessary, you can determine the usable channels by
stepping the channel selection through a number of
channels on a tuner with the transmitter set to OFF.
Those channels on which the RF indicator of the tuner
does not light are usable.
•
If there is a TV broadcasting station near by, do not use
the station's channel.
•
The unit may not operate correctly if it is turned on again
immediately after turning off the power while in setting
mode. Pause for a few seconds or more before turning on
the power again.
