Thank you for choosing the JD55-PR RF Repeater System For your safety, we shall recommend to read these instructions carefully before using, operating and adjusting this product. This operating instruction applies only to the JD55-PR RF Repeater System.
For PCS 1900 MHz System The JD55-PR RF Repeater System is a bi-directional amplifier designed specially for inbuilding RF Coverage extension ( about 100 ㎡ and more) for cellular services. If you have a coverage problem in your home, office, small shop and restaurant, the JD55-PR RF Repeater System will be a proper solution for your needs. 1.
For PCS 1900 MHz System 2. Function of Each part 1) DONOR ANT. Port for connecting Donor antenna ( Patch Antenna ) 2) SERVICE ANT. Port for connecting Service antenna ( Dipole Antenna ) 3) GAIN CONTROL SWITCH Switch for controlling the system gain to optimize the service environment of Repeater. For using this function, refer to the instructions of LED Alarm and Gain Control Switch as following pages. 4) ALARM LED There are two LED indicators on the unit.
For PCS 1900 MHz System * Shutdown Algorithm Detection for 10 second Detection for 1 second Detection for 1 second Detection for 1 second Input S/D for 10 seconds S/D for 10 seconds S/D for 30 m inutes S/D com pletely The embedded detector of repeater is designed to detect whether the RF output power of the repeater exceeds a prescribe limit on the downlink or uplink. If it catches some overpowers during 10 seconds and more, the repeater itself shutdown automatically.
For PCS 1900 MHz System 3. Instructions for using each device 1) Antenna set Antenna set is comprised of Donor & Service Antenna. To install Antenna set, follow the instructions as bellows. ① Donor Antenna ( Patch Antenna ) ② Assistant Device for installing donor Ant. * If necessary, you can use the fixing bracket differently provided.
For PCS 1900 MHz System (★★★ Warning ★★★) When connecting the Donor / Service antenna to the Repeater Body, Do not use too strong power. It is threaten to be connector defected. 2) Gain control switch For system optimizing, you can adjust the system gain through gain control switch according to the LED status and service quality of subscriber’s terminal. In this case, start from step 4 to step1. (★★★ Warning ★★★) Gain being set up to 43dB in the factory.
