The silicone skin we provide with the handset for the X9 Remote and Follow trolleys protects the handset and must always be fitted to the handset except when charging. In addition, once charging is complete the small rubber plug must be fitted back into the charging port. 

Doing both of these things means that the handset will remain showerproof. It will not, however, be totally waterproof. Water and electronics are natural enemies and you must take care to make sure no water ever gets inside the handset. 

For instance: 

• Never allow the handset to be immersed in water and don't wash it
• If you want to wash the silicon skin, remove it from the handset before washing it and dry it thoroughly before replacing it
• If you use the handset in the rain or other wet conditions, remove the silicone skin as soon as you have finished playing and wipe both handset and silicone skin dry to remove any any moisture that may have found its way down the edges of the silicone skin. 
• Don't store the handset anywhere that water might get into it
