After church service, my Pastor talked to me about the charging base for the translation units we use there. He said something is wrong with the charging base.

The charging base is actually a case holding the translating unites senders and receivers.

It holds about 29 receivers and one transmitter.

It has separate power source for charging; with a very high amp rate.

There are about total of 8 screws on both edge of this charging case. Once these screws were off, it is very easy to flip the board and see what beneath that.

Every base gets its own power source so if one base gone bad, it will not affect the rest of the bases in that case. I consider that very smart actually.

This is a close up of one charging base. These charging bases are in very good conditions due to the fact I do maintenance on it every six months.

Usually I look for bad capacitors 2200uf/25 volts. This time all the capacitors were in good shape.

When I looked closely, the only thing I could find wrong in this charging case is its dirtiness and it has to be cleaned. The contacts were not that clean.

This is the charging contact pins in the bottom of the main transmitter. It was really bad and the photo shows after it was cleaned.

I have this special tool for cleaning and rubbing off corrosion on contact pins. It is a very cheap device yet very effective in cleaning tiny contact pins.

Two grey devices are the receivers and the black one is the transmitter. They use UHF signals and very handy for translations because they run on batteries. I usually do the translation in church on Sunday. It is fun and challenging.

Once all the cleaning and rubbing was finished, put all the parts back together and as you can see charging is being done to these translating units. Mission Accomplished.

    I am curious where you did buy this special tool for cleaning and rubbing off corrosion on contact pins Waleed? Especially because you say it is a very cheap device yet very effective in cleaning tiny contact pins.
    Thanks for the article.
