Resetting of IC-7300's built-in clock2020年09月08日 09時40分49秒

For quite some time now, IC-7300's clock has been resetting itself if it is not energized for even a few hours.

This is because the internal battery is dead, but I think that many people have experienced the same phenomenon. It's not a good idea to keep turn on the power just for the sake of the clock...

It is said that the manufacturer confirms the retention time of the backup battery at the time of shipment for about one month by the charge of two days, but...


ICOM explains that a study of the charge-discharge cycle characteristics of rechargeable watch batteries shows a 10% discharge depth of over 300 cycles.................

But it doesn't actually last that long.

If you are a brave man who fixes it yourself, the following parts will be charged.
Part name: ML414HIV01E 
Part Code:3020000390
The unit price, excluding tax, is 200 yen (excluding tax)
Required number: 2 pieces
The above prices are for Japan. I think the prices are different in your country.

However, be aware that you may see failing case scattered around the internet.

Even if the clock is off, it doesn't affect other functions, so I'm leaving it alone.
But if you're curious, there is software that can calibrate the clock from your PC.

IC7300BKT Icom IC-7300 CAT Control


This software allows you to set the clock to the current time on your IC-7300 when it is connected via a USB cable.


Select Set Mode, enter your country's time difference for the arrow and click on the square to set the time.

For me, I don't care about it and leave it at that... 

I think that the battery should be a coin type lithium battery like the motherboard of PC.

The backup battery for ICOM IC-7300 is ML414H. The MS621R and MS421R are also available as equivalent products. The ML1220, which has a larger capacity, can also be used. If you have a problem with your ICOM battery, you may be able to use one of those batteries instead of the genuine ICOM ones. If you use non-genuine batteries, please do so at your own risk.
