DectCom uses DECT technology to provide full duplex hands free communication, with rechargeable beltpacks and combined base station / antenna. Based on the International DECT 1.8Ghz technical specification, this system gives licence free communications over a distance of up to 300 metres which may be extended by use of repeaters. The Base station can connect either four or eight beltpacks, all in a conference. Connection to Mercury / Commander /Orator intercom or other 4 wire system is available via an interface. The range features a rugged beltpack with built in rechargeable battery, which can also run on dry cells with an optional battery adapter. The rechargeable battery will last for at least 15 hours continuous transmission. Charging time (with the supplied AC adaptor) is around 5 hours. A range of headsets with electret mic is available to meet differing requirements as well as a acoustic tube in ear moulding for use by presenters. The beltpack has simple level up/down and VOX up/down controls, and a “connect” button to register to the base station. It is only necessary to do this the first time the beltpack is used with the base station Simple Windows based software is available to set the audio parameters and is included in the programming kit

Frequently asked questions Q. Do I need to obtain expensive frequency licences to use the DectCom system? A. No. The DECT system is licence free in mre than 110 countries Q. Where can I use DECT based systems? A. You can use DECT 1.8Ghz in most of the world (except US, Canada and Japan, who use DECT 2.4Ghz. For full coverage visit www.dect.ch, the DECT Forum, and look under Global Presence Q. Will the Trilogy DectCom log on to Telephony DECT in error? A. No, there is an access code that would ensure the Trilogy DectCom will not log on to Telephony DECT. Q. Do I need to assign the handsets to the base each time a system is turned on? A. No, the assignment process only needs to be carried out the first time a system is used. A system which has been used previously only needs to be turned on, and all previously assigned handsets will find the base station. Q. The handset is assigned a base station, but why is there is no sound in the headset? A. Check that the LED is blinking correctly: once every three seconds. If the LED blinks twice every three seconds, you need only quickly press the assign button. Having done so, the handset will join in the conference group. Q. I can hear what others say, but cannot speak with them. Why is this? A. Make sure that Vox isn't turned up too high. Press "Vox" several times until a short tone is heard in the headset. If you still cannot speak with the others, the problem may be that the handset was used with a different type of microphone, compared with the one it presently is employing. Press "Vol" and "Vox" simultaneously until a short tone is heard in the headset. The headset should work correctly following this. Q. The base station turns itself off after a short time. What is wrong? A. Make certain that the power supply is connected correctly and turned on. If not, then the base station will run on its internal back-up battery only. Q. The handset beeps constantly. Why is this? A. The handset's battery need to be charged. Connect the charger. The LED will stop blinking when the handset is fully charged.
