    RT2048 INTRODUCTION The RT2048 VHF radiotelephone has been designed to comply with the increasing demands of a highly technological product, which means high quality, small size, etc. The RT2048 is furthermore designed to fit into the Compact 2000 module programme.

  • Page 6: General Description

    1 INTRODUCTION RT2048 1.1. GENERAL DESCRIPTION VHF RT2048 is an all solid state constructed microcomputer controlled VHF radiotelephone, intended for ship/ship and ship/shore communication. VHF RT2048 can operate in both simplex and semi-duplex mode. VHF RT2048 includes all 55 international and U.S. VHF marine channels, and is as standard prepared for up to 10 private channels, selected as simplex or semi-duplex channels in the frequency band 154.4 - 163.75 MHz.

    PREVENTIVE MAINTENANCE If SAILOR RT2048 has been installed in a proper way the maintenance can be reduced to an overhaul at each visit of the service staff. Then inspect the set, the antenna, cables, and plugs for mechanical damages, salt deposits, corrosion, and any foreign material.

  • Page 28: Test Probe

    3 SERVICE RT2048 3.4. TEST PROBE All measurings made by means of a test probe will be relative measurements. For quantitative measurings the diode probe should be calibrated by means of a signal generator at a certain impedance level (50 ohm) as a function of frequency.

  • Page 29: Troubleshooting

    SAILOR RT2048 has a number of trimming cores and trimmers, which must not be touched unless adjustments as specified in section 3.5. ADJUSTMENT PROCEDURE can be made.

  • Page 30: Replacement Of Components

    3 SERVICE RT2048 3.7. REPLACEMENT OF COMPONENTS When replacing transistors, diodes, resistors, capacitors and similar components you must use a small „pencil“ soldering iron of 30 to 75 Watt rating. The soldering must be performed rapidly to avoid overheating, and the use of a tin sucker is recommended, as otherwise there is a risk that both the components and the printed circuit will be spoiled.
