The best way to maintain the S1:
Connections - If it is permanently installed in a listening room or studio, use zip ties and cable extensions to prevent connection damage. Create a break away connection especially if you are in a swivel chair.
Electrical - After use, always recharge the battery
Force - A good, solid body connection enhances the tactile experience. Laying or leaning on the SubPac forcibly impedes the transducer physics and can lead to damage.
Heat - if you find that heat is building up in long, intense listening sessions take a break and allow the unit to cool down.
