Telex Operating Instructions RadioCom TM Wireless IFB TT-16 16 Channel Transmitter TR-16 16 Channel Receiver
INTRODUCTION WHAT IS THE TELEX WIRELESS IFB SYSTEM? WHAT FREQUENCY BAND DOES THE TELEX SYSTEM OPERATE IN? Transmitter: The transmitter generates and amplifies a RF (Radio Frequency) carrier signal, modulates this carrier with the microphone signal, and radiates the modulated RF carrier. The Telex Systems feature a synthesized transmitter and a synthesized receiver operating in the VHF Band between 64-68 MHz. See Table 1 for standard frequencies available.
When ever the sys tem is in use, the trans mit ter should be left on to prevent the receiver from picking up outside interference. OFTEN ASKED QUESTIONS Question: Can more than one system be used si- multaneously? Question: What is E.D.R.? Answer: E.D.R. stands for enhanced Dynamic Answer: Yes but never on the same frequency. You will need to have different frequencies for every receiver/transmitter combination. Range (companded) audio. E.D.R.
TR-16 SYNTHESIZED RECEIVER Treble Control: A push button treble control is provided to enhance higher frequency audio when the button is engaged, indicated by . General Description TR-16 Head phone Jack: The re ceiver jack ac cepts a 0.140-inch (3.5 mm) diameter miniature plug. A variety of earsets or headphones can be plugged into this jack for listening. The Telex TR-16 Receiver is a component of a system which operates on sixteen (16) user selectable channels in the 64 to 68 MHz frequency band.

should be used for small to medium sized venues and whenever multiple systems are being used. Press SET when the power is set and the Unbalanced Input level will flash. Antenna 12-15V AC/DC + - Unbalanced Input And Level Adjustment If the unbalanced audio input will not be used, with the "Unbalanced Audio Level" flashing use the DOWN button to set the level to OFF and press set to go to Balance Input Selection.
MULTIPLE SYS TEM IN STALLATIONS: As with any radio device, interference can occur at any time. The frequencies offered are shared with other legitimate users. The severity of interference varies with the distance to the interfering station. Multiple systems further complicate installations. The following steps are suggested in order to achieve best results in your installation. Enhanced Dynamic Range (E.D.R.) Operation The Telex TT-16 Trans mit ter is equipped with E.D.R.
TR-16 SYNTHESIZED RECEIVER 1) To engage the E.D.R function turn the TR-16 off with the volume control thumb wheel. 2) Press and hold the SET button while you turn the TR-16 back on. The E.D.R. symbol will be displayed in the lower right corner to indicate the mode is active. Keep a clear, unobstructed path between the transmitter and receiver antennas for a clear transmission. 3) Repeat the procedure to disable the E.D.R. function. 1 2 Lock Out The TR-16 SET button can be locked to prevent E.D.R.
Low Battery Indication 1) When there is approximately 10% of the battery life left, an animated battery symbol will flash alternately with the channel letter in the LCD display. 2) When there is only 5% battery life left, the battery symbol will constantly flash in the display. E.D.R. Low Battery Display BATTERY REPLACEMENT The TR-16 Receiver uses two (2) AA batteries. When the batteries are low the sound will be distorted.
BATTERY INFORMATION General Alkaline Batteries Improper battery selection, use, installation and care are the cause of numerous wireless system failures. Alkaline batteries such as Mallory’s DURACELL® or Eveready’s ENERGIZER® provide the most reliable operation in wireless transmitters and receivers. The use of low cost carbon-zinc batteries is NOT RECOMMENDED. *ENERGIZER® is a registered trademark of Union Carbide Corporation. *DURACELL® is a reg is tered trade mark of Duracell Inc.
Make sure the “signal path” between the transmitter and receiver(s) is unobstructed. You should always be able to visually locate the antenna of the transmitter at all times. DO NOT - Mount the transmitter on, or next to, metal such as beams, walls with metal studs, etc. This will “detune” the transmitter antenna which can result in loss of signal at the receiver.
TROUBLESHOOTING Reread the sections of this manual to make sure you have completed system set-up properly. If you are unable to solve the problem, contact the dealer from whom you purchased the system for assistance. PROBLEM SOLUTION DISTORTION -System's audio quality seems distorted at medium to high input levels Reduce audio gain on transmitter by adjusting the gain controls. HISS - System seems to produce a "hiss" which is undesirable.
FCC INFORMATION The Telex TR-16 receiver is authorized under part 15 of the FCC Regulations. Changes or modifications to this equipment could void the user’s authority to operate the equipment. The Telex Model TT-16 transmitter is authorized under Federal Communications Commission and Industry Canada Rules. Licensing of the Transmitter, if required, is the users responsibility and licensability depends upon the users classification, and frequency selected.
