Speaker

You would think that the easiest part of the setup would be the speaker, and most of the time you would be correct. Most modern sets, be they base station, mobile, or HH come with internal speakers and you don't have to worry. Older P.M.R. sets often came with an external speaker which was permanently connected to the set or had a specialised plug. For the purpose of this section, class this as being an internal speaker.

However, if you do not have an internal speaker, or want to connect headphones, an external speaker or whatever takes your fancy, you need to make sure that what you are plugging in is okay for that set. It is possible to damage the output chip of the radio, requiring expensive repairs if you connect the wrong type of speaker. Generally, the only two things to worry about and the resistance and the size of the speaker - the one usually being related to the other. Larger speakers having a higher resistance can put an excessive load on the output chip and overload it.
