Office Telephone System Bug

As business telecommunication/switchboard systems are different from normal telephone lines the use of transmitters or telecorder is impractical. This is where the transmitter plays a vital role and up until now it was virtually impossible to bug a business telephone system. The transmitter operates with a coin type battery and only comes on when the phone is being used. The battery life is approximately 100 hours of telephone usage.Normally the transmitter is fitted inside the handset and will monitor that particular telephone. If needed the handset can be unplugged from the telephone, from one office and plugged into another office and so different telephones can be monitored, provided of course, the handset is not permanently glued together in which case the transmitter will have to be fitted inside the telephone. The transmitter is relatively easy to fit and we can supply full fitting instructions but because a slight telephone knowledge may be required we can fit it in for you. Normally for this service we will need the telephone at our premises and this may be arranged when placing the order.POWER: 3V coin cell (supplied)
