ENQUIRIES must be addressed to the Head Office of the Company, International
Buildings, 67/73, Kingsway, LONDON, W.C.
2.

ILLUSTRATIONS are not binding, owing to improvements made from time to time.

OVERALL DIMENSIONS AND WEIGHTS are given to assist shipping
estimates, but must be accepted in all cases as approximate only.

ORDERS should always quote the Catalogue Number of the article. The private
codes may be used when ordering by cable. The standard instruments,
which are generally kept in stock, should be ordered if possible, as
alterations cause delay in delivery and extra cost.

DISCOUNT is allowed to the trade and for export.

DELIVERY is made free in Great Britain, or f.o.b. British Port.

PACKING CASES, except boxes invoiced at 6d. or under, will be credited in full if

CLAIMS for shortages or damaged goods must be made on the Carriers or Railway
Company within three days of receipt, and our assistance to secure a
satisfactory adjustment will be gladly given.

NOTE. No goods, except samples, will be received at the
London Office.

Foreword
Our manufactures are so varied that it would be practically impossible to
illustrate and describe all in a publication of this nature. This catalogue therefore,
contains illustrations and particulars of the apparatus and parts mostly used and
which are generally kept in stock.
Our aim is to furnish such information that customers can readily determine
the type of article best suited to their particular needs.
The name
Ericsson is world-renowned for telephone products which are
distinctive and unexcelled for design, workmanship and reliability.
In a modernly-equipped factory we manufacture only the very best equipments
from the highest-grade materials. We have a staff of competent engineers who are
always ready to assist customers with their problems.
The apparatus is arranged under three main sections, viz.:
Telephones

Switchboards

Accessories
Each of these three sections is preceded by a coloured leaf on which is
printed an index of the articles following.
To facilitate the ordering of spares or replacements such as cords, receivers
and transmitters, the code numbers of these parts are given on the same page as
the instrument of which they form integral parts, as well as in the "Accessories
Section." It is, however, advisable for the customer to state also the code
number of the instrument for which they require the parts.
We have had considerable experience and have thoroughly investigated the
requirements in manufacturing our products, to give long service and withstand the
severe climatic conditions of the
Tropics.
When ordering goods for use in the
Tropics or very damp climates the letter
" T " must be added to the code numbers given in this catalogue and as lightning
arresters and earth terminal are not generally fitted on these telephones, they must
be specially ordered.
Where instruments or other apparatus are required for operating on
existing systems, the customer should give the important particulars of the
system, as this will often save correspondence and thus expedite delivery of the
goods.
