User manual FENDER PASSPORT DC-DC CONVERTER

[. . . ] Batteries generate explosive gases when being charged, operated and stored. Always allow clear air space for adequate ventilation. Never allow a spark or open flame to come into proximity of a battery; explosion may result. [. . . ] If a clip accidentally comes off during use of the Passport, make sure to turn off the DC/DC Converter before re-connecting to the battery. Failure to do so could damage both the DC/DC Converter unit and the Passport unit. Turn on the power switch on the DC/DC Converter only after reconnecting the clips. You are now ready to turn on the DC/DC Converter and with it the Passport system. Important: The front panel Power Switch on the Passport Portable Sound System is now inoperative and has no effect on the On/Off status of the Passport Portable Sound System. The Power supply switch function is now controlled by the On/Off switch on the DC/DC Converter. Battery life may differ according to a number of variables including: Battery condition Battery charge state Temperature Program type and continuity Passport Control settings FYI When using any electronic equipment after transportation in cold weather or whenever the equipment is appreciably colder than the room in which it will be operated, condensation may form on external and internal surfaces. This can result in short circuits, damage to the equipment and possibly exposing humans to risk of electrical shock!Always allow sufficient time for equipment to reach ambient temperature and for any condensation to evaporate BEFORE plugging in or otherwise connecting to power. This is true for all electrical equipment! If possible, use a new or as new battery and always fully charge the battery before use. We recommend the use of a 48 amp/hour or greater capacity battery. Your own specific circumstances and applications will dictate larger or smaller batteries. Note: If an in-vehicle battery is used to operate the system, make sure there is enough charge left to start the vehicle at the end of your event. The ability of a battery to maintain a sufficient charge to turn over a vehicle may be significantly impaired by use of the system depending on the condition of the battery and the nature and circumstances of the system's use. It is advisable to use a free standing battery or back up battery to avoid this occurrence. [. . . ] You have completed this phase of the installation and the Passport is now ready to operate on DC/DC power. FYI: It is NOT necessary to remove these fuses when operating the Passport via an AC power current. CARE AND CLEANING To clean your Passport DC/DC Converter, use only a damp cloth to wipe the surface of a disconnected DC/DC Converter. Occasionally wipe unconnected cables carefully with a damp cloth. [. . . ]
