Once the call button is paired with your receiver monitor, operation is straightforward:
- To send a call signal, simply press the button firmly.
- The LED indicator on the button will illuminate briefly, confirming that a signal has been transmitted.
- The call button itself does not produce any sound; the signal is received and audibly indicated by the paired receiver monitor.
5. Maintenance
5.1 Cleaning
Due to its waterproof design, the call button can be easily cleaned. Use a soft, damp cloth with mild soap or an alcohol-based disinfectant to wipe the surface. Do not use abrasive cleaners or immerse the entire unit in water.
