Care and Maintenance

- Avoid rough handling: The receiver and transmitter may be damaged if dropped. Use the snap - on belt clip whenever possible
- Remove batteries when you store unit for a long time: When battery becomes exhausted, it may leak and damage the instrument. Even a new battery may leak because of a slight imperfection. Occasionally check for leakage
- Keep battery terminals and contacts clean: Inspect to ensure that they are not corroded. If they are, polish them with a pencil eraser
- Inspect cords and connectors frequently—they are subject to wear: Replace frayed cords before they break
