THE HEALTH AND SAFETY AT WORK ACT 1974
We are required under the Health and Safety at Work Act 1974, to make available to users of this equipment certain information
regarding its safe use.+
The equipment, when used in normal or prescribed applications within the parameters set for its mechanical and electrical performance,
should not cause any danger or hazard to health or safety if normal engineering practices are observed and they are used in accordance
with the instructions supplied.
If, in specific cases, circumstances exist in which a potential hazard may be brought about by careless or improper use, these will be
pointed out and the necessary precautions emphasised.
While we provide the fullest possible user information relating to the proper use of this equipment, if there is any doubt whatsoever about
any aspect, the user should contact the Product Safety Officer at Feedback Instruments Limited, Crowborough.
This equipment should not be used by inexperienced users unless they are under supervision.
We are required by European Directives to indicate on our equipment panels certain areas and warnings that require attention by the
user. These have been indicated in the specified way by yellow labels with black printing, the meaning of any labels that may be fixed to
the instrument are shown below:

PRODUCT IMPROVEMENTS
We maintain a policy of continuous product improvement by incorporating the latest developments and components into our equipment,
even up to the time of dispatch.
All major changes are incorporated into up-dated editions of our manuals and this manual was believed to be correct at the time of
printing. However, some product changes which do not affect the instructional capability of the equipment, may not be included until it is
necessary to incorporate other significant changes.
COMPONENT REPLACEMENT
Where components are of a ‘Safety Critical’ nature, i.e. all components involved with the supply or carrying of voltages at supply
potential or higher, these must be replaced with components of equal international safety approval in order to maintain full equipment
safety.
In order to maintain compliance with international directives, all replacement components should be identical to those originally supplied.
Any component may be ordered direct from Feedback or its agents by quoting the following information:
1. Equipment type
3. Component reference
2. Component value
4. Equipment serial number
Components can often be replaced by alternatives available locally, however we cannot therefore guarantee continued performance
either to published specification or compliance with international standards.
