Biological precautions
Warning: Foul systems can be a source of serious biological hazards. Wear appropriate personal
protective equipment (PPE) when handling the P550c.
Always use heavy-duty industrial gloves when withdrawing a rod from a sewer.
Battery precautions
The controller contains a Li-Ion rechargeable battery. Only use charging equipment provided by
Pearpoint. The use of alternative chargers may cause a safety hazard and/or reduce the life of the
battery.
The battery is designed to protect itself against over-discharge, overcharge and short circuit between
charge terminals. Other batteries may not provide these safety circuits.
Warning: Exposing the controller’s Li-Ion battery to high temperatures (over 60°C or 140°F) may
activate safety systems and cause a permanent battery failure.
