Users Manual

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. Operating Instructions RF Repeater System Product No.: JD55-PR JD TECK LTD. .
For PCS 1900 MHz System 2The JD55-PR RF Repeater System is a bi-directional amplifier designed specially for in-building 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. Basic Description of Each Part
For PCS 1900 MHz System 3 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. One is for displaying the Power Input Status, the other is for operating status. a. Power LED The power indicator, marked “ Power “ acts as power alarm. It monitors the function of the power supply. Blue LED ON : Normal Status LED Status Red LED ON : Power supply failure b. Automatic Shutdown Function If there are some abnormal output powers on the uplink or downlink path, the repeater will be shutdown automatically to avoid any problem. Blue LED ON : Normal Status LED Status Red LED ON : Failure Status If the red indicator lights up, it is designed that the related circuit operates to have the repeater shutdown to protect repeater itself. Despite several corrections, the indicator is still kept red on, it should be secured the isolation more between the donor antenna and service antenna.
For PCS 1900 MHz System 4 * Shutdown Algorithm 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. Meanwhile, the repeater operates as the above algorithm during shutdown. * Shutdown Level Specifications Remarks Downlink +15 ± 2 dBm / Total Red LED ON Uplink +15 ± 2 dBm / 1FA Red LED ON 5) DC POWER SUPPLY Port for connecting exterior power adapter that supplies DC7V power to the repeater.. 6) HOLE for PICTURE FRAME Hole for hanging the picture provided ( Optional ). Detection for 10 second S/D for 10 seconds Input Detection for 1 second S/D for 10 secondsDetection for 1 second Detection for 1 second S/D for 30 minutes S/D completely
For PCS 1900 MHz System 53. 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. ③ Donor Antenna cable ④ Service Antenna ( Dipole Antenna )
For PCS 1900 MHz System 6(★★★ 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. 3) ALARM LED Can be checked the operating status through LED Lamp in front of Repeater body. If there is any failure status, follow the instruction of the above 2) Gain Control Switch over and over. If RED LED on, the repeater is stopped automatically to avoid any damage. For rebooting the repeater, must be supplied power again. Being still kept failure status despite of , remove the power supply from the repeater. 4) Power Supply Exterior adapter having AC 110 V input supplies DC 7 V power to the repeater to run active circuits. Blue LED On is normal status. (★★★ Warning ★★★) Gain being set up to 43dB in the factory. Please adjust it as field condition
For PCS 1900 MHz System 7 5) Installation on the wall The bracket provided can be used to install repeater on the wall as a below figure. 4. Trouble Shooting If the repeater is not normal status as followings, please remove power supply off to avoid additional damage and contact service center for repairs. ① Overheating status ② Red LED on ( For 35 seconds and more ) ③ Power LED failure (★★★ Caution ★★★) This device shall only be installed and operated by the FCC licensee for the PCS service.
