This new top of the range intelligent transmitter and receiver/recorder will give you many years' reliable service. The Uctr is manufactured by a leading company, and by using latest surface mount technology will give reliability not just some times but every time. This system is very easy to install and the bug will transmit both sides of every call to the intelligent receiver/recorder that will record everything with superb clarity. Fixed frequency on UHF means there are no tuning dials or controls. Most importantly on this system everything is done automatically and is very discrete. The receiver/recorder will record every telephone conversation and you can listen to the recorded tape at your leisure. The very tiny bug can be fitted inside the normal telephone socket or anywhere along the line. Fitting practically takes less then a minute and does not require any further attention. The bug only measures 21mm x 14mm x 11mm and is  self powered so does not require any batteries The receiver/recorder can be left anywhere up to a distance of 400 meters (see footnote). The receiver/recorder is fully automatic which means all you do is set it to auto record function and let it do the rest for you automatically. When a call is made or received the receiver/recorder starts to record both sides of the conversation, and when the handset is replaced, the receiver/ recorder will stop recording and automatically be ready for anymore calls. This also means no wasted tape between any number of calls. The recording can either be made at normal tape speed or slow tape speed for longer record times (up to 2.5 hours). To listen to the recording simply switch from auto record to tape play. Rewind tape and listen at your leisure. So now in your absence your friend will always ensure nothing is missed and keep you fully informed. As this system is top of the range and super discrete you will always be one step ahead of your adversary when it comes to that vital information.
