Tip for cleaning charger connections

A customer in the Northern City of Hull, in the UK was having problems with his six-way multi charger, and told us it was ‘dodgy’.

The issue was not a fault with the charger, but due to the contacts on both the battery and the charger battery contacts, becoming dirty.

Over time the copper contacts on both the battery and the charger, which need to be clean, become dirty.

This is particularly an issue in harsh industrial environments, and can be a cause of the radio charger appearing to have a fault, when the radio is placed into it to charge.

A tip is to regularly clean both the copper contacts at the base of the rechargeable battery (on the back of the radio), and also lightly clean the spring contacts on the charger.

Ensure that the charger is switched off and disconnected from the mains power supply.

Then using a soft pencil eraser (rubber), gently rub the copper contacts to clean them.

This will help make electrical contact between the charger and the radio battery.

Why have the connections become dirty?

Air contaminants such as industrial dust, or corrosive atmospheres such as the marine industry, cause a build up of dirt or corrosion on the electrical contacts.

Preventative Maintenance

To prevent the inconvenience of your radios suffering this charging fault, regular cleaning and inspection of the battery and charger contacts is advised by Yesway.

For light manufacturing environments, once a month will normally be sufficient.

For heavy industrial and marine offshore environments, a weekly check and a quick clean is advised.

Hull Street Angels Trinity

We are proud to have recently helped the new Hull Street Angels Trinity Charity with their radio communications.

The charity has recently launched, and operates on a Friday & Saturday night to patrol the Trinity area of central Hull, providing help and assistance to people out enjoying themselves in Hull, who may need a friendly face and possibly assistance.

The charity works closely with the authorities, such as CCTV, and the radios are capable of communicating directly with someone in the control room.

After meeting with the charities coordinator, discussing the charities  requirements for communicating by radio, and carrying out range testing, the system supplied was based on Vertex-Standard UHF hand-portable radios.

Helping Charity in Hull set up communications system

We are currently helping a Hull based charity set up a hand-portable communications network in central Hull.

During our initial meeting with the charity coordinator we explained the options and possible issues, such as reduction in the strength of the signals due to the tall buildings.

Then we carried out a test which involved walking around the proposed coverage area with a Vertex-Standard VX231 hand-portable, and communicating back to another hand-portable at the charities base location.

The range survey proved that a radio repeater, which is used to boost range, was not required. This means that the charity was able to get operational within their budget, and without compromising on equipment quality.
