Product Detail
The Lectrosonics WM Hybrid Wireless Beltpack Transmitter, upgraded with the VT500 WATER Lavalier microphone, is a top - notch choice for audio transmission in wet or dusty environments. Its O - ring sealed battery compartments and input jack, compression sealed antenna port, and gasket sealed control panel and back cover make it highly durable. Dual AA batteries offer double the operating time compared to earlier watertight transmitter designs. The large membrane switches, control panel, and a bright backlit LCD provide an excellent user - friendly interface.

Using the Lectrosonics WM Hybrid Wireless Beltpack Transmitter is easy. First, insert two AA lithium batteries into the battery compartment. Make sure the compartment is sealed properly to keep out dust and water. Connect your microphone to the 2.5 mm locking audio input jack.
To select the frequency and output power, use the membrane switches on the control panel. The LCD will show you the settings. You can choose different output powers depending on whether you want to save battery or get a better operating range.
When using it in wet or dusty environments, thanks to its special seals, you don't have to worry too much about damage. But try to avoid long - term immersion in water.
For maintenance, regularly check the O - rings and other seals for wear and tear. Replace them if needed using the included O - ring kit. Keep the transmitter clean by gently wiping it with a dry cloth. If you're not using it for a long time, remove the batteries to prevent corrosion.
