ROYTPRF-900HWireless Transceiver System, Handset

Wireless Transceiver System (TPRF-900) Manual 1. Getting Started . Introduction: This equipment has been manufactured and tested under strict quality control conditions. This Wireless Transceiver System has been tested within a 1000 feet radius. The receiving chips use a Super Heterodyne method, while the Base and Hand sets use and coincides with a Digital Coded method. In case of frequencies overlapping with other waves, up to 40 different channels can be selected for clearer reception by manually using the Channel Switch button . Equipments: a. Base Set – 1 unit b. Hand Set – 1 unit c. Headset (optional) – 2 units d. Microphone – 1 unit e. Rechargeable Battery – 1 pack f. User’s Manual - 1 book * Accessories parts are subject to change without any notice for functional improvements. . Cautions: a. Use only the given antenna with the Base Set b. Do not immerse in water or keep in humid areas c. Do not place near TV, speakers, or other electronic devices d. Before installation, check power supply and voltage to avoid hazards e. Do not apply force or shock to the unit f. Do not disassemble the unit . Parts Description: Base Set: Hand Set: 2. Functions: This Wireless Transceiver System can automatically search, find, and memorize the best reception within 40 channels. Therefore, top of the line clarity and communication is guaranteed. a. Hand Set: The Talk ON/OFF switch, can activate the Base unit. b. Base Set: The RJ-45 #6 pin is used for controlling the communication. If a LOW (TTL:”L”) signal is received, the communication is enabled regardless the Hand Set is ON or OFF. If a HIGH (TTL:"L") signal is received, the communication is disconnected. c. Channel Surfing: If reception becomes unclear, press the Channel Switch button once. d. Security: The CPU and EEPROM can choose from one million different passwords to prevent eavesdropping. e. Paging: The Base Set can page the Hand Set for communication. f. Standby: While charging, the Hand Set is in standby mode. g. Communication Range: When the Hand Set goes out of range, a warning beep will sound on the Hand Set. h. Low Battery: When the Hand Set is low on battery, a warning beep will sound and a warning light will appear. 3. Base and Hand Set Installation Base Set a. Connect the RJ-45 connector to the Base Set b. Connect the Microphone (optional Headset) to the Base Set Hand Set a. The battery pack is not built-in the Hand Set for safety reasons. Connect the battery pack to the Hand Set and then turn the power switch ON (located in the battery storage area) b. Prior to use, charge the unit by placing the Hand Set in the Base Set for at least 3~5 hours c.

Rechargeable Battery Pack It is recommended that before using, charge the unit by placing the Hand Set in the Base Set for at least 3~5 hours. Replacing the Battery Pack a. Remove the battery cover on the Hand Set b. Turn the power switch OFF (located in the battery storage area) c. Detach the battery pack cable from Hand Set d. Connect the new battery pack to the Hand Set and then turn the power switch ON (located in the battery storage area) e. Close the battery cover 5. Recommendations a. Prior to use, charge the unit by placing the Hand Set in the Base Set for at least 3~5 hours b. The LED on the Base Set indicates Charging Mode. If LED light does not turn on, call the A/S center c. If the Hand Set is not in use for long periods, turn the power switch OFF (located in the battery storage area). d. Check the LED on Hand Set for Low Battery status e. Charge Hand Set when not in use for short periods 6. Troubleshooting Problems Check Points No reception - check the battery status - check the connection and cables - check the communication range Poor reception, static, noise - change the location of Base Set - check the communication range - check to see if placed near TV, speakers, or other electronic devices FCC COMPLIANCE STATEMENT THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.

SK TECH CO., LTD. Page 1 of 1 SKT SKTTRT-031215-009 FCC ID: ROYTPRF-900H Operational Description (RF part) The HANDSET and BASE have the different RF modules, RU0926H18HKB and RU0902B18HKB respectively, which is a short –range, full duplex wireless radio transceiver. See the attached block diagrams and schematics. RX Audio/DATA Part Audio signals, which are received and demodulated in the RF module, are expended by Compander IC (KA8507D) and then adjusted by variable resistor (SVR2). The adjusted audio signals are amplified, and transmitted to Earphone. DATA, which are received and demodulated in the RF module, are amplified via transistors, TR8 & TR1, and then transmitted to RX DATA port on the Microprocessor (KS57P01504), which has 4K-byte one-time-programmable ROM. TX Audio/DATA Part Audio signals, which are input by MIC, are compressed by Compander IC and then adjusted by SVR1. The adjusted audio signals are modulated in the RF module. TX DATA, which are controlled by the Microprocessor, are directly modulated and radiated. EEPROM & RESET circuit EEPROM is used for storage of the identification code. As Power-ON-Reset functions, this circuit is activated in LOW. LOW battery indicator circuit (HANDSET) Where the voltage of the battery is below 3.1 V, the LOW battery indicated circuit is activated by IC K1A7031F and the LOWDET terminal of the Microprocessor. ANTENNA The antenna is affixed on it and no external ground is required or used with HANDSET.
