4.2.1 Mounting a Telephone Handset correctly in the Cradle
Fig.4.10

alignment jig prior to fitting
a telephone handset
For the given handset, make sure that the centering forks are placed in suitable holes in the
cradle bar. The optimum way of positioning the centering forks is so that they point in opposite
directions, i.e., the centering fork closest to the sight points forwards and the rear centering fork
points backwards.
1) Place the cradle in the alignment jig and tighten the knob on the back of the fixture.
2) Retract the support feet and the end stop and widen the centering forks, so that they will
not interfere with the handset.
3) Tip down the sight and lock it in position.
4) Make sure that the handset can be supported by both support feet by selecting an
appropriate mounting hole for the rear support.
5) The handset should be supported with only three spikes; one positioned in the rear support
foot and two positioned in the front support foot below the ERP or vice versa. Position the
spikes in suitable holes in the support feet. Choose whether to use short or long spikes or
both. Choose spike positions that do not interfere with projections caused by batteries,
antennas, etc.
6) Position the handset so that its ECRP is in the middle of the alignment jig sight and tighten
the support foot directly below the ERP until the ear-cap plane is positioned correctly
against the under side of the sight.
7) Extend the rear support foot until it just supports the other end of the handset.
8) Adjust the end stop until it just touches the edge of the handset.
