1.2.8. Conditions
This apparatus is not designed for use under controlled conditions of temperature and
relative humidity.
1.2.9. Series Connection
This apparatus when connected into the loop connection between the main apparatus
and the PSTN introduces a voltage drop at a current of 40mA of 0.300V.
The apparatus should not be used in conjunction with other series connected
apparatus such that the aggregate declared voltage drops together with that of any relevant wiring at
40mA, exceeds 2.0 volts.
1.2.10.Facilities
This apparatus has been approved for use as a telephone hybrid unit (four wire to two
wire converter) and for use with a series connected simple telephone. Any other usage will invalidate
the approval of the apparatus if as a result it then ceases to comply with the standards against which
approval was gained.
1.2.11.Statutory Mark
Approved for connection to telecommunications systems specified in the instructions
for use subject to the conditions set out in them.
