Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT:
Because of the danger of introducing additional hazards, do not install substitute parts or
perform any unauthorized modification to the instrument. Return the instrument to a Raytech
service department for service to ensure proper operation and that safety features are
maintained.
Instruments, which appear damaged or defective, should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.
