Notes and warnings for DL35 in compliance with IEC-348 and FCC A
This instrument of protection class has been constructed and tested in compliance with IEC publication 348, Safety Regulations for Electronic Measuring Instruments, and has left the factoryin faultless condition in regard to safety. To maintain this condition and to ensure hazard-free operation, the user must observe the notes and warnings in these operating instructions. The instrument is intended for indoor use. It can be occasionally exposed to temperatures between +50 C and -10 C without any adverse effects on its reliability. Before switching on, ensure that the operatingvoltage set on the instrument matches the power supply voltage. If this instrument is to be operated using an autotransformer and a power supply of higher voltage, it must be ensured that the base of the transformer is connected to the neutral wire of the power supply. The power connector may be inserted only in a socket with a ground contact. The protective action must not be nullified by anextension lead without an equipment grounding conductor.

When covers are opened or parts removed, except where this is possible by hand, live parts may be exposed. Connection points can also be live. Before adjustment, servicing, corrective maintenance or replacement of parts, the instruments must be disconnectedfrom all voltage sources if it has to be opened. It must be ensured that only fuses of the specified type and the specified rated amperage are used as replacement. The use of repaired fuses or short circuiting of the fuse holder is strictly forbidden. If it appears that hazard-free operation is no longer possible, the instrument must be shut down and secured against inadvertent usage. It may beassumed that hazard-free operation is no longer possible * * * * when the instrument shows signs of visible damage, when the instrument no longer operates, after lengthy storage under adverse conditions, after severe transport stress.

Warning: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instructions manual, may causeinterference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference in which case the user at hisown expense will be required to take whatever measures may be required to correct the interference.
