1.0 Regulatory & Safety Information

1.1 FCC Warning Statement

WARNING: This device complies with CFR 47, Part 24 of the FCC

rules. Any modification not expressly approved by the manufacturer

could invalidate the user's authority to operate the device.

1.2 Safety Information

CAUTION: In order to comply with FCC rules for Radio Frequency Exposure,

the following must be observed:

The PROPAGATOR must be installed such that a minimum separation distance

of 1.25” (3 cm.) is maintained between each antenna face (the large white plastic

15” X 15” surfaces on each side of the chassis) and any persons.

.0 Equipment Description 1.2 Physical Configuration Figure 1 is an illustration of the PCS-1900-xx “Propagator” Repeater (hereafter referred to as the SSR) indicating important features. As shown in the illustration there is a main electronics housing (chassis) that has a square shape with rounded corners. The chassis is attached to a mounting base that incorporates an azimuth rotation feature with detents. The approximate size of the chassis is 15” X 15” X 4”; the corners have a 3” radius.

1.4 Operational Environment The SSR has been designed to operate properly in a temperature and humidity controlled indoor environment. Operation in environments where the ambient temperature is outside the 30o -105o F range or the relative humidity is greater than 50% may result in unsatisfactory performance. Exposure to temperatures outside the 10o -120o F range or relative humidity greater than 90% may result in permanent damage to the unit. 2.0 Installation Guide Lines 2.

the glass the 73 dB system (50 dB active) gain setting is recommended for maximum stability margin. Figure 4 is the next best installation location: mounted on an interior wall surface of typical gypsum wallboard (drywall) construction about 7 or 8 feet off the floor but not too close to the ceiling. Be careful to position the SSR between metal studs in the wall if present. Extensive stability testing has shown this mounting location to provide stable operation for both gain settings of the SSR.

3.0 Operation Guide Lines 3.1 Status Indicating Light Emitting Diodes (LEDs) Four small status indicating LEDs are visible on the Mobile unit facing side of the SSR; they provide the following information (see Figure 1): Green LED nearest the mounting base. Red LED adjacent to Green Power LED described above. Green LED adjacent to red LED described above. Green LED near the edge of the SSR opposite the green Power described above.
PAGE 6
If a spectrum analyzer is not available, a less certain but useful way to confirm satisfactory operation is to make a phone call using a hand set that operates in the same band as the SSR. The audio quality is usually badly garbled and distorted when the SSR is operating in an unstable manner.

APPENDIX C: Gain Adjustment The standard factory active gain setting for the Propagator is 50dB. Some installation locations provide a very low multi-path feedback environment and can support a stable active gain of 60dB. Factory trained service personnel can easily set the gain of the Propagator to either gain setting using the following procedure: 1) Remove the white plastic radome on the mobile side of the Propagator.
