10. The Line Out and Tone Out signals each require a PTO line to be connected to the
appropriate pins of socket SK2. Alternatively, the Tone Out signal can be combined
with the Line Out signal by the fitting of link LK10. This allows both signals to be
fed from the Line Out pins (4 and 6) to one PTO line instead of two.
11. The Line Out and Tone Out termination loading link settings are pre-set during
manufacture to meet the requirements set by the regulatory authority of the
appropriate country, and should not require resetting during installation. However,
the range of possible link settings are detailed in Table 2.
