All the tuner modules installed into the MB-806 are set to the available channels within the selected channel group.

After the automatic detection and selection of available channels finish, you can change the group and channel on each tuner module manually.

Notes

•Do the automatic detection and selection of available channels with the channel group other than channel group 00.

•When there are unavailable channels due to extraneous radio wave and the channel could not be selected on some tuner modules, “NO CH” appears on the display of those tuner modules. If this happens, select the channel group with no interference from extraneous radio wave, and repeat the procedure above.

The attenuation level can be set during signal transmission.

1 Do the following while there is no signal transmission. Turn on the transmitter while pressing down the SET button, and press the SET button repeatedly until the attenuation level indication appears in the display section.

Do the following while there is signal transmission. Press the SET button repeatedly until the attenuation level indication appears in the display section.

2 Press the + or – button to select the attenuation level.

The selectable range is from 0 dB to 21 dB in steps of 3 dB (the factory setting is 0 dB).

3 Do the following while there is no signal transmission. Set the POWER switch to OFF to complete the setting, or press the SET button to set other items.

The results are stored in memory. The change becomes effective the next time you turn on the transmitter by setting the POWER switch to ON.
