How to troubleshoot Simrad RS90S that will not power up?
If your Simrad Radio won't power up, it might be due to a blown fuse or lack of voltage reaching the transceiver. Start by inspecting the power cable for any cuts, breaks, or squashed sections. Replace the 10 Amp fuse. Also, check the battery voltage, ensuring it's at least 10.5V.
Why is the battery symbol displayed on my Simrad Radio?
If the battery symbol is displayed on your Simrad Radio, it indicates that the power supply is too low. Verify the battery voltage, ensuring it's at least 10.5 V ± 0.5 V DC. Also, check the alternator on the vessel.
What to do if Simrad RS90S Radio transceiver blows the fuse when switched on?
If your Simrad Radio transceiver blows the fuse immediately when you turn it on, the power wires might be reversed. Ensure that the red wire is connected to the positive battery terminal and the black wire is connected to the negative battery terminal.
What to do if GPS alarm sounds on Simrad RS90S Radio and LCD shows 'Please check GPS link!'?
If your Simrad Radio GPS alarm sounds and the LCD displays 'Please check GPS link!' with the NO GPS symbol, it means GPS data has been lost. Check that the GPS cable is physically connected and verify the polarity of the GPS cable. Also, check the baud rate setting of the GPS, if applicable, it should be 4800, and parity should be set to NONE.
Why does my Simrad RS90S speaker make popping noises when the engine is running?
If your Simrad Radio speaker makes popping or whining noises when the vessel’s engine is running, electrical noise might be interfering with the transceiver. Try re-routing the power cables away from the engine. You can also add a noise suppressor to the power cable or use resistive spark plug wires and/or an alternator whine filter.
Why are Simrad RS90S Radio transmissions always on low power?
If transmissions on your Simrad Radio are always on low power, even when high (Hi) power is selected, the antenna may be faulty. Test the transceiver with a different antenna. Have the antenna checked out.
How to fix no sound from Simrad RS90S external speaker?
If there is no sound from the external speaker of your Simrad Radio, ensure that the external speaker is enabled in the Setup menu. Also, check that the external speaker cable is physically connected and verify the soldering of the external speaker cable.
