Move away from the CS and identify the CS coverage area within which the radio signal strength level
is greater than "03". Draw the area on the map.

Air synchronization is established. However, it is necessary to monitor
the status of synchronization using the Maintenance Console.
This is necessary because IP-CSs may be reset due to synchronization
failure if the radio signal strength fluctuates depending on changes in
the installation environment such as opening/closing doors.
Level: 00 to 02
May be reset due to synchronization failure of CSs
3.
Repeat steps 1 and 2 for other CSs, and relocate the CSs when necessary.
a.
Plan the location of the CS so that its clock signal source is within range of the CS where the radio
signal strength level is "07".
Example
: Master CS1
: Master CS2
: Slave CSs (Primary CS: Master CS1, Secondary CS: Master CS2)
•
When planning the location of CS
, make sure that CS
(clock signal source) is within the
area where the radio signal strength level of CS
is "07".
