3.3 Setting up
1. Push down the two snap locks on the right and left of the battery compartment and open it.
Now you can adjust the GT/MT switch and the gain control .
2. Make sure that the transmitter and receiver are on the same frequency.
3. The LED of the TS 900 C will flash for a moment when the transmitter is switched on and
indicates the normal battery status. When the LED fails to flash, there is no battery inserted, the
battery is leaking or inserted incorrectly. The battery status of the TS 900 M can be seen in the
LC-Display.

3.4 Adjusting the Input Gain
1. Switch on the TS 900 beltpack transmitter with the ON/OFF switch . Turn the gain control
fully anti-clockwise to minimum gain.
2. Speak into the microphone at the maximum level you expect to use. We recommend you use the
letter “U” as a spoken “U” has a relatively good sine wave shape. Adjust the gain control to
the desired gain. On the NE 900 receiver the AF level must not show any clipping. When miking
instruments, play at the maximum level you expect to use.
