    RT62 & RT64 1 GENERAL 1.1 Introduction The RT62 and RT64 fixed VHF radios are designed by Simrad and manufactured at our modern factory facility in the UK. The radio is designed to meet or exceed stringent International Regulations including ETS300-162 and EN301-025.

  • Page 7: Rt62 And Rt64

    The RT64 features a second watchkeeping receiver, allowing it to use the Digital Selective Calling (DSC) system on VHF chan- nel 70. For this the RT64 will need to be linked to the Simrad Class D DSC control unit DSC1400.

  • Page 8: Operation

    RT62 & RT64 2 OPERATION 2.1 Location of Controls The RT62 and RT64 VHFs are very simple to operate, using only five buttons and three rotary knobs to access a variety of functions. The functions available will depend on whether the radio is a scanning or non-scanning version (scanning func- tions are not permitted in certain countries).

  • Page 9: Operation - Scanning Versions

    The radio is switched on using the volume knob. The VHF starts up automatically on channel 16* at maximum power (25w). *This can be changed - contact Simrad Agent for details 2.2.1 Function (F) / Backlight ( ) Secondary functions are only available on scanning versions of NOTE - the VHF.

    RT62 & RT64 2.2.2 Power (1/25) / Channel Memory (M+) Although the radio has a maximum transmit power of 25 watts, this is not always necessary if communicating with a sta- tion or vessel that is very close. To reduce power consumption, the transmit power can be reduced to 1 watt.

  • Page 11: Dual Watch (D/W) / Channel Inhibit ( )

    Instruction Manual 2.2.3 Dual Watch (D/W) / Channel Inhibit ( ) + Revert function Dual Watch enables the radio to scan between the selected channel and the priority channel (normally Ch16). To activate Dual Watch Mode, select the channel and press D/W - the D/W legend will be displayed on the LCD.

  • Page 12: Triwatch

    RT62 & RT64 REVERT Function If D/W is pressed when CH16 is selected, the VHF will revert to the previously selected channel. 2.2.4 Triwatch The Triwatch function is similar to Dual Watch, but this scans between the selected working channel, the User channel and the Priority channel.

  • Page 13: Channel 16 (16)

    Instruction Manual 2.2.6 Channel 16 (16) Will automatically select Channel 16 on High Power when pressed. Any function active (Dual Watch, Scanning etc) will be cancelled. 2.2.7 Squelch (Sq) This knob is used to adjust the receiver muting threshold (squelch) level. To cut out weaker signals, increase the squelch until the background interference noise disappears.

  • Page 14: User Channel

    RT62 & RT64 2.2.10 User Channel (F then 16) This function allows a user selectable personal channel to be programmed. Select the channel, press F then press and hold 16.

  • Page 15: Memory Mode (Scanning Versions Only)

    Instruction Manual 2.4 Memory Mode This function is only available on scanning versions of the VHF. It allows the radio to operate using only the channels programmed into the channel memory.

  • Page 19: Installation

    Although the RT62/RT64 radio is waterproof when flush mounted, it is recommended that it is not installed where it will be exposed to continuous direct sunlight, as this will even- tually damage the LCD display.
  • Page 20 RT62 & RT64 The radio is fixed to the bracket using a simple clamp arrange- ment. The peg on the left side of the radio is slotted into the hole in the bracket. The clamp on the right side of the radio can then be slid into the slotted aperture on the bracket and tightened to hold the radio firmly in place (Fig 3.3).

  • Page 21: Electrical Installation

    Instruction Manual 3.2 Electrical Installation The RT62/64 has four electrical connections - the handset/fist- mike socket is on the front panel below the LCD display (Fig 3.4A). The other three are situated on the back of the case - the antenna socket is on the right (Fig 3.4B), a 3.5mm jack socket...

  • Page 22: Antenna Installation Recommendations

    VHF radios are related to poor antenna siting, faulty cabling, poor quality cable joints and low voltage supply. Even a VHF as highly advanced as the RT62/RT64 cannot com- pensate for these factors. Therefore, if replacing an existing VHF installation, it is important that these factors are checked when installing the radio.

  • Page 23: Electrical Interference Suppression

    Instruction Manual agent should be able to provide specific advice on antenna choice for the vessel it is to be fitted to. The antenna coaxial cable and any connectors used must be rated at 50Ω. Under no circumstances should standard domes- tic TV cable and connectors be used.
