Telex WT-10, FMR-10 operating instructions

4.Verify Reception. When the transmitter is turned on: (FMR-10) the RF meter will illuminate, indicating that the receiver is pick- ing up the signal. If this does not happen, make sure that the trans- mitter and receiver are set to the same channels.

5.Unmute the audio by sliding the audio switch (immediately be- low the mic element) towards the windscreen. Speak or sing into the microphone and you should hear your voice through the PA / sound system.

6.Adjustment of the transmitter audio gain - if necessary. The transmitter audio gain is set to a mid level which should be suit- able for most situations. However, for loud or soft speakers or singers, an adjustment may be necessary. First, speak or sing into the microphone and listen closely. If the gain is too high, you will hear distortion, and if the gain is too low, the signal will be low. In either situation, an adjustment may be necessary.

To adjust the transmitter gain, gently insert the provided screw- driver (or other 3/32-in./2.4mm screwdriver) into the hole near the head of the transmitter (see Figure 12). Turn lightly until the screwdriver tip drops into the slot in the level control. Gently turn counterclockwise until the control stops (the mic output is attenu- ated but not “off”). Slowly turn the mic-level control up while lis- tening to the audio. If the audio becomes distorted, turn the mic level control down (counter-clockwise) about 1/8 turn.

Note: Operate with the transmitter audio gain set as high as possi- ble without distortion, for the best signal to noise ratio.

7.Test performance. Check to see that the RF meter on the FMR-10 receiver is illuminated, an indication that the receiver is picking up the signal. Then, “walk” the intended area of use and make sure that there are no barriers to reception or sources of in- terference. If problems are encountered, see Troubleshooting Guide.
