6. Plug the power cable on the supplied AC adapter into a con-
venient power outlet.
7. Switch the receiver ON with the POWER switch (1a).
Note: For easy channel identification in a multichannel setup, you
can replace the snap fitted color code platelet (1j) with a dif-
ferent-color platelet included in the optional Color Coding Kit.

9.4.5. Antennas

For optimum reception, make sure to extend the two telescoping
antennas (1e) exactly as far as specified for each Frequency Set
in Table 1 on page 39.

9.5. System Adjustments

1. Handheld transmitter: Using the supplied screwdriver
(1q), set the GAIN control (2e) so that on the receiver the green
AF LED (1h) will light constantly and the red PEAK LED (1h) on
the receiver and the status LED (2b) on the transmitter will only
flash on the loudest signal peaks.
Bodypack transmitter: Using the supplied screwdriver
(1q), set the GAIN control (3j) so that the green AF LED (1h) on
the receiver will light constantly and the status LED (3c) on the
transmitter as well as the red PEAK LED (1h) on the receiver will
only flash on the loudest signal peaks.
2. The red PEAK LED (1h) on the receiver and/or the status LED
(2b, 3c) on the transmitter lighting brightly means the transmit-
ter is overloaded. Turn the GAIN control (2e) or (3j) on the
transmitter CCW to the point that the PEAK (1h) and status (3c)
LEDs will only flash occasionally.
3. Set the VOLUME control (1b) on the receiver so that the receiv-
er output will optimally drive the connected device (e.g., mixer

9.5.1. Multichannel Systems

If reception on the selected carrier frequency is disturbed, set the
carrier frequencies for all WMS 60 channels up or
down one or two steps with the respective CHANNEL controls
(1d, 2g, 3f) on each transmitter and receiver.
This is necessary to provide the minimum frequency spacing re-
