Why will my Simrad Axis 150 not transmit on 5W but is OK on 1W?
If your Simrad Radio will not transmit on 5W but works fine on 1W, it could be due to a low battery charge. When transmitting at full power, the radio draws more current. Recharge the battery to resolve this. Alternatively, some channels may be restricted to low power transmission only; consult your national authority for clarification.
How to fix Simrad Radio if it will not switch on?
If your Simrad Radio unit will not switch on, the battery may not be charged. Re-charge the battery. Also, ensure the battery is fully locked in the radio.
Why is my Simrad Radio scan locking on a channel without a signal?
If the Scan or Memory Scan on your Simrad Radio is locking onto a channel without a signal, it may be due to noise on the channel holding the scan. Try increasing the squelch level. You can also inhibit the channel from the scan.
Why Dual Watch is not being entered on my Simrad Axis 150 Radio?
If Dual Watch is not being entered on your Simrad Radio, it could be because a priority channel is selected (normally CH16). Select a working channel.
