Circuits and Components This manual covers both BM7 models. Their comparative specifications are given for identification purposes. This manual has been produced as an aid to the trained Technician who undertakes the servicing of these instruments. The design of the instrument is such that a minimum of equipment is required and components are easily accessible. If the customer has not advised that the repair may be undertaken irrespective of your charges, we strongly recommend that the instrument should be examined and an estimate submitted before any work is undertaken. This procedure, and the acceptance of the estimate, will provide a safeguard against disputes arising over a charge for the work after the necessary repairs have been completed.
