USERS MANUAL

 Owners Manual/Operating Instructions Telex Model PST-170 Auditory Assistance Transmitter Carefully inspect your Auditory Assistance Transmitter. If there is any damage or shortages, please refer to the “Warranty Information Section”. Set-up Instructions: Power: Power is provided by 2 “AA” size batteries. Alkaline batteries provide the best battery life. Nickel Cadmium or Nickel Metal Hydride rechargeable batteries can be used also but with shorter  battery life. Install batteries as shown in the illustrations but do not apply power to the transmitter at this time.  CAUTION:  Do not attempt to recharge Alkaline Batteries as this may result in personal injury. Charge Pins are provided on the bottom of the unit that fit TELEX drop in chargers. Frequency/Channel Considerations:  As with any radio device, interference can occur at any time. The frequencies offered are shared with other legitimate users. Check the frequency/channel with the  matching receiver to see if any interference is present. If interference is present, choose a different channel. The severity of interference varies with location and distance to the interfering station. If the interference is weak on all channels, this is probably acceptable since your transmitter will cover the interference and is unlikely to interfere with other users. Multiple Channel Systems require other considerations but each channel should be checked as above.  Transmitter Location:  Select a clear, unobstructed path between the transmitter and the receiver if possible, for  best performance. The transmitter should not be used between objects such as metallic building structures and file cabinets as this can cause short distance performance and reflections that could cause fading of the signal.  Place the transmitter on the users belt or pocket, preferably with the antenna facing the receiver. Do not coil the atenna and put it in a pocket. This will severely reduce the operating distance.   Transmitter Operation:  Now that you have checked all of the channels you intend to use, apply power to the transmitter by moving the Toggle Switch on top of the transmitter towards the Function Display. The display will light up for approximately 8-10 seconds allowing better viewing in low light situations.  Pressing either of  the Function Buttons will also cause the screen to light up for 8-10 seconds. Use the function push buttons to  select any of the items listed in the Function Instructions below.  Antenna:  The transmitter uses a flexible wire “trailing” antenna that is permanently attached to comply with FCC Part 15 Rules. Do not cut or lengthen the antenna . This is a tuned antenna and modification will shorten the operating range.
