The carefully planned grouping of the parts makes it possible to
determine in which part the fault lies. on receipt of a complaint.
Since replacement of faulty parts is the rule. the maintenance man
can. before leaving. be advised of the probable measures to be
taken . Such a possibility enables more repairs to be carried out
per day than if the real cause is not discovered until the man
arrives.
Lengthy jobs such as soldering and replacement will be dispensed
with. The supply of spare parts required for fault correction is so
limited that it can always be easily checked. The great advantage
of the replacement system is that on-the-spot determination of
the real cause of a fault is almost unnecessary - a prerequisite
for employing less qualified maintenance staff.
Thus, a less qualified repairman can correct more faults than a
trained man previously could, and there is greater guarantee of
better work done, which implies a reduction in staff costs for each
fault correction. By always replacing faulty units with reliable,
tested units produced - from tested components and high-quality
material , the risk of repeated visits is considerably reduced.
The simplified maintenance work permits careful planning of the
routes and calculating the time for replacement of faulty parts.
Today, the possibilities of correcting more faults, the reduced
risk of repeated calls owing to unsatisfactory repairs, the ease
of planning routes, and the saving in time, mean a large reduction
in travelling expenses.
By simply using a screwdriver. any unit of the telephone can be
replaced. The faulty unit is then sent to the central workshop.
Here. a small team of qualified repairers with tools and testing
equipment can work in proper conditions and the work will be
done more accurately.
In order to systematically utilize the advantages which the tele-
phone instruments provide from the maintenance point of view, it
is vital that repairs in a central workshop are carried out
rationally.
L M Ericsson has investigated the vital problem of overhaul and
maintenance work, and are prepared to give advice on rational
planning and running of a central workshop, and supply the
necessary equipment.
The aim of the suggested methods is to make each operation
simple , timesaving and easy to learn so as to enable relative
inexperienced people to produce uniform quality of work.

Ericsson can also supply forms for recording the measures
taken. These forms may then be used as a basis for keeping
statistical records of repair work and also for pricing.
