RT62 & RT64 Instruction Manual 1.2 RT62 and RT64 1 GENERAL Both the RT62 and RT64 are available with either a fistmike or telephone handset, and offer the same features. The details in this owner’s manual apply to both models. 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.
RT62 & RT64 Instruction Manual 2.2 Operation - Scanning Versions 2 OPERATION 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 2.1 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.
Instruction Manual RT62 & RT64 2.2.2 Power (1/25) / Channel Memory (M+) 2.2.3 Dual Watch (D/W) / Channel Inhibit ( ) + Revert function Although the radio has a maximum transmit power of 25 watts, this is not always necessary if communicating with a station or vessel that is very close. To reduce power consumption, the transmit power can be reduced to 1 watt. This key operates as a toggle, switching between 1w and 25w (Fig 2.3). NOTE - Some channels are restricted to 1w transmit power.
Instruction Manual RT62 & RT64 REVERT Function 2.2.6 Channel 16 (16) If D/W is pressed when CH16 is selected, the VHF will revert to the previously selected channel. Will automatically select Channel 16 on High Power when pressed. Any function active (Dual Watch, Scanning etc) will be cancelled. 2.2.4 Triwatch 2.2.7 Squelch (Sq) The Triwatch function is similar to Dual Watch, but this scans between the selected working channel, the User channel and the Priority channel.
Instruction Manual RT62 & RT64 2.2.10 User Channel (F then 16) 2.4 Memory Mode This function allows a user selectable personal channel to be programmed. Select the channel, press F then press and hold 16. Initially the display will show the previously selected user channel, but after 2 seconds the new user channel will be shown and USE will appear on the bottom line of the display the button may now be released. This function is only available on scanning versions of the VHF.

Please enquire with your national licensing authority for details of permitted channel sets. 2.7 Fistmike Operation The RT62 and RT64 radios are available with either a telephone handset or fistmike. The fistmike incorporates three buttons which allows the user to remotely control some functions of the radio (Fig 2.10). The radio will revert to normal operation if it is switched off then on again. 2.
RT62 & RT64 Instruction Manual 2.7.1 User Programmable Key To program the user key function, turn the radio off, then press and hold the user key on the fistmike while switching the radio on (Fig 2.11) - the display on the radio will show UP (User Programming). 3 INSTALLATION 3.1 VHF Installation The radio should be sited so that engine noise and vibration or other background noise do not make it difficult for the operator to hear.
RT62 & RT64 Instruction Manual The radio is fixed to the bracket using a simple clamp arrangement. 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). The rake angle of the radio can be adjusted by slackening the clamp. 3.

The flying lead from the rear of the radio can then be plugged into the power supply lead. Note that the configuration of the plug prevents incorrect connection. 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.
RT62 & RT64 Instruction Manual 4.2 Transmission Range 4 APPENDIX Because VHF signals travel in a straight line and are not reflected back off the ionosphere as lower frequency signals are, the range of VHF signals is limited to ‘line of sight’, beyond which the other vessel passes behind the curve of the Earth. Therefore, the range will increase greatly the higher above sea level the antenna is, as Fig 5.1 illustrates (assuming maximum transmission power is used): 4.
