Tuning the Time Division Multiplex (TDM) frequencies manually
The
If you are able to receive WS broadcasters, it is NOT necessary to perform this operation. However, there may be occasional changes in the transmitted signal which may require use of this function. Worldspace will inform you of any alteration in the frequency range available in your area.
1When the power is on, press and hold the WS button for 3 seconds or more.
The currently received TDM grid number and polarity (L or R) appear in the display.

2Use the rotary encoder dial to select the TDM frequency. Turn the rotary encoder dial clockwise for higher grid numbers, and counterclockwise for lower grid numbers.
(counterclockwise)(clockwise)
TUNING/SELECT
The order of the TDM frequencies changes in the display as follows. When the highest grid position (GRID 82R) is reached, the count will continue on from the lowest position (GRID 1 L) and similarly in the reverse direction.

3When the correct grid number and polarity is selected, broadcaster reception begins and normal operation returns.
