NP… additionatinaly if you are planning on using the TR3A in the UK it can be fitted with a UK keyboard, which has a slightly different key layout but includes a £ sign key missing from the US International standard US type.
All you need to do is change keyboard type in windows, or when first installing.
For the type in my previous images you want windows set to US International, for a UK one you would set it to United Kingdom
