Frequency Lock

Use the arrow keys to select normal (10 mW) or high power (50/100 mW**). Use the normal power setting to conserve batteries or prevent RF overload at the receiver.

*High power setting not available with models sold in countries that prohibit its use.

**High power value varies with model.

Setting Transmitter Gain

Adjust the transmitter gain and input sensitivity so that the Audio LEDs on the receiver peak within the yellow range during use. On the bodypack transmitter, you can change the sensitivity setting to compensate for different audio levels when connecting different intruments or microphones to the input.

To adjust gain, turn on the transmitter and press the enter button. Scroll down to the Gain parameter or the Sens parameter (bodypack only) and press enter again. Use the arrow keys to adjust the setting and press enter to save it (Exit cancels without saving).

RF Safety Mode

This special feature temporarily mutes RF broadcast. This allows you to change frequency settings on a transmitter without accidentally “cutting in” on a channel being used by another transmitter.

1.Turn the transmitter off.

2.Hold down exit key while turning on the transmitter power (for handheld microphones, you need to pull the battery cover off the handle). The LCD flashes while the unit is in RF safety mode.

3.Change group and channel settings as you normally would—the transmitter will not broadcast.

4.Power the transmitter off and on to exit RF safety mode.
