The PS Digital ICS Repeater is easy to install in most circumstances (as illustrate in Scenario 1).
However, there are few circumstances where external antenna would be required. The following
scenarios are examples of how the optional package contents can be used.
Scenario 2: no signal at the window - optional antenna can be used as external donor (receiving)
antenna and installed at a location with better signal (for example: top/side of a building).
Scenario 3: there are no windows near the intended service area/room - optional antenna can be
used as external donor (receiving) antenna and installed at the closest window.
Scenario 4: additional area/room requires enhance signal from the repeater - optional antenna
can be used as additional service antenna and installed at second service area/room. If more
than two areas/rooms require service, additional cabling & splitter can be used to cover multiple
areas/rooms. Please consult with a Coiler representative for more accessory options.
To install optional antenna, please follow steps below.
(1) Remove base cover (see Section 3 steps 1 & 2 for instructions).
(2a) Use wrench tool to disconnect built in donor antenna (for scenario 2 & 3).
(2b) Use wrench tool to remove the cover on MS CPL (for scenario 4).
(3a) Connect 90° connector to Donor port (graph 4, hollow arrow), then tighten connection.
(3b) Connect 90° connector to MS CPL port (graph 4, solid arrow), then tighten connection.
(4) Snap base cover back in place (see Section 3 step 4 for instruction).
(5) Determine the location of the external antenna then secure the cable along the wall.
(6) Connect external antenna to the other end of the cable, tighten connection.
(7a) Mounting with double sided foam pad - the front side of the antenna should be facing either
the source of the signal (used as donor) or the service area (used as service). When used as a
service, the foam pad would always be applied on the back side of the antenna (see graph 5). As
a donor, the foam pad can be applied to the front of the antenna and mount on window glass
indoors, or apply the foam pad to the back of the antenna and mount on window glass outdoors.
(7b) Mount the antenna with mounting kit. Please use appropriate tools to secure the screws.
(8) Power on the repeater and check the Isolation LED and make sure there are 5 green LEDs (the
higher the isolation value, the better it is for the performance of the repeater). If there are less than
5 green LED's, please try to relocate or reposition the antenna or the main repeater unit.

Question
Answer & solution
Why does isolation LED keep changing? When no external antenna is connected, the ICS (Isolation
Cancellation System) function of the repeater is always working
to reduce antenna signal feedbacks.
Why is there still low or no signal after the
installation of the equipment?
(1) Ensure that the signal level (RSSI) is sufficient - the
recommended RSSI should show minimum 3 green RSSI LED.
Use external donor antenna if neccessary.
(2) Ensure that all connections are tightly fastened.
(3) Ensure that the output power of the adaptor is DC 6V and
the green power LED is illuminated.
(4) Reconnect the power cable.
Why is the alarm LED RED?
This can only happen when input RSSI is too strong (when signal
is greater than -32dBm). If this is the case, the use of repeater is
not needed. Please do not use the repeater if signal quality is
already sufficient.
Why is the repeater’s signal not stable?
(1) Ensure that the input signal is stable.
(2) Ensure that there are no object(s) in front of the PS repeater.
(3) Ensure that the RF cable is not damaged.
(4) If external donor antenna is in use, ensure that there are 5
green isolation LEDs on constantly. If isolation LED is less than 5,
please increase the distance between the donor antenna and
the repeater unit.
(5) Reconnect the power cable.
**If abnormal status persists after all the corrective actions are taken, please contact your sales agent for further instructions.
