Using the Lectrosonics WM Digital Hybrid Wireless Beltpack Transmitter is quite straightforward. First, insert two 1.5 - volt AA lithium batteries into the battery compartment. Make sure the O - rings are in place to keep the compartment sealed. Then, connect your microphone or other audio source to the 2.5 mm locking micro audio input jack.
Next, use the control panel with its membrane switches to set the frequency, output power, and other settings. You can choose an output power of 50, 100, or 250 mW depending on whether you want to save battery life or need a longer operating range. The LCD screen will show you all the important information about the settings.
When it comes to compatibility, this transmitter has programmable modes that allow it to work with a wide variety of receivers. So, just select the appropriate mode for your receiver.
**Note**: This transmitter is designed for wet or dusty environments, but it's still a good idea to avoid submerging it in water. Also, don't expose it to extreme temperatures.
For maintenance, check the O - rings regularly for signs of wear and replace them if necessary. Keep the antenna clean and make sure it's not damaged. If you're not using the transmitter for a long time, remove the batteries to prevent corrosion. And that's it - enjoy using your high - quality wireless transmitter!
