4. Reduction of the number of stations and paging zones
which results from the use of the Tieline Unit TI-52.
1. Mounting one (1) piece of the TI-52 decreases the number of the
LMU-52A (the 7th or the 15th LMU-52A) by one (1).
2. Unless the PIU-52A is used, the system can have up to 8 more
stations by placing an LMU-52A in the 8th or the 16th position.
3. When the system uses the tieline function, the second unit of
the PIU-52A (paging zones 8 - 15) cannot be used.
