Safety Considerations
This product and manual must be thoroughly understood before attempting installation and operation.
To do so without proper knowledge can result in equipment failure and bodily injury.
Caution: Before applying ac power, be sure that the equipment has be properly configured for the
available line voltage. Attempted operation at the wrong voltage can result in damage and voids the
warranty. See the manuals section on installation. DO NOT operate equipment with cover removed.
Earth Ground: All Datron products are supplied with a standard, 3-wire, grounded ac plug. DO
NOT attempt to disable the ground terminal by using 2-wire adapters of any type. Any disconnection
of the equipment ground causes a potential shock hazard that could result in personal injury. DO NOT
operate any equipment until a suitable ground has been established. Consult the manual section on
grounding.
Servicing: Only trained personnel should carry out servicing. To avoid electric shock, DO NOT open
the case unless qualified to do so. Various measurements and adjustments described in this manual are
performed in ac power applied and the protective covers removed. Capacitors (particularly the large
power supply electrolytics) can remain charged for a considerable time after the unit has been shut
off. Use particular care when working around them, as a short circuit can release sufficient energy to
cause damage to the equipment and possible injury.
To protect against fire hazard, always replace line fuses with ones of the same current rating and type
(normal delay, slow-blow, etc.). DO NOT use higher value replacements in an attempt to prevent fuse
failure. If fuses are failing repeatedly this indicates a probable defect in the equipment that needs
attention.
Use only genuine Datron factory parts for full performance and safety of this product.
