TRANSMITTER OPERATION
IMPORTANT INFORMATION
-
When more wireless devices are used at the same time, each transmitter / receiver
pair shall be set to its own channel that must be different from all already used.
A channel (frequency) can be used for 1 transmitter only (2 or more transmitters
cannot be set to the same channel).
-
It is possible to use up to 16 channels simultaneously.
For instance, the following 10 channels can be used simultaneously without any
interference:
-
group 1, channel 1
798.125 MHz
-
group 2, channel 1
798.325 MHz
-
group 2, channel 2
800.725 MHz
-
group 2, channel 5
807.925 MHz
-
group 3, channel 4

In case of interferences due to lighting equipments, computers, other radio transmitters,
etc. nearby, it is advisable to try different frequencies.

Wireless microphones should be used in an open-space with no obstacles (especially
metallic objects) between transmitters and receivers.
