OFTEN ASKED QUESTIONS

Question: Can more than one system be used si- multaneously?

Answer: Yes but never on the same frequency. You will need to have different frequencies for every re- ceiver/transmitter combination.

Question: Is the system more sensitive in any one particular direction?

Answer: No, the transmitter’s antenna radiates equally in all directions, but the signal is attenuated by your body, walls or other surrounding objects. The receiving antenna is essentially sensitive in all directions as well.

Whenever the system is in use, the transmitter should be left on to prevent the receiver from pick- ing up outside interference.

Question: What is E.D.R.?

Answer: E.D.R. stands for enhanced Dynamic Range (companded) audio. E.D.R. improves the sig- nal-to-noise ratio providing much better audio qual- ity.

Question: Can the TT-16 and TR-16 be used with existing TR-34 and TT-44 products.

Answer: Yes, as long as the E.D.R. feature is dis- abled on the TT-16 and TR-16.

Question: Can the receiver receive other transmis- sions when the transmitter is turned off?

Answer: Yes it can. Telex systems operate in the VHF Band between 64-68 MHz. However, it is not susceptible to radio wave skip, CB’ers or standard FM radio transmissions. It is on TV Broadcast chan- nels 3 and 4. So it is best to use the channels in your system that are not on the TV broadcast chan- nel in your area. See Table 1.

The frequency your system operates on is computer selected for least interference, but there is no such thing as a 100% clear channel all the time.

If the system is going to be used in a permanent fixed location, it should operate interference free un- til such a time or date when someone else begins using the same frequency.

If the system is going to be moving among various locations, you may run into occasional frequency conflicts.
