1、S-14308XZ-C1 Dec. 2006 DIGITAL VOICE REPEATER id-rp2000v This service manual describes the latest service information for the ID-RP2000V DIGITAL VOICE REPEATER at the time of publication. NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than 15 V. This will ruin t

2、he transceiver. DO NOT reverse the polarities of the power supply when connecting the transceiver. DO NOT apply an RF signal of more than 20 dBm (100 mW) to the antenna connector. This could damage the transceivers front end. To upgrade quality, any electrical or mechanical parts and internal circui

3、ts are subject to change without notice or obligation. Be sure to include the following four points when ordering replacement parts: 1. 10-digit order numbers 2. Component part number and name 3. Equipment model name and unit name 4. Quantity required 1110003491 S.IC TA31136FNG ID-RP2000V MAIN UNIT

DO NOT force any of the variable components. Turn them slowly and smoothly. 4. DO NOT short any circui

6、ts or electronic parts. An insulated tuning tool MUST be used for all adjustments. 5. DO NOT keep power ON for a long time when the transceiver is defective. 6. DO NOT transmit power into a signal generator or a sweep generator. 7. ALWAYS connect a 50 dB to 60 dB attenuator between the transceiver a

7、nd a deviation meter or spectrum analyzer when using such test equipment. 8. READ the instructions of test equipment thoroughly before connecting equipment to the transceiver.
