What is your return policy?
You may return the equipment within 30 days from the date of purchase for any reason. The equipment must be returned to TN Communications LLC, P.O. Box 3698, Salem OR 97302. It must be returned in the same condition it was received, in the original individual box and pouch, and with accessories (earphones/headphones or microphones) enclosed. Immediately upon receipt, we will refund the money paid, minus shipping and handling, which is not refundable.

What does the warranty cover?
The 1-year manufacturer's warranty covers both transmitter and receiver if they cease working properly through normal use.  Please return it to us for free repair or replacement. Our address is TN Communications, P.O. Box 3698, Salem OR 97302. The warranty does not cover microphones or earphones.

Is your equipment easy to set up?
Very easy. You insert 2 AAA batteries into each unit, turn on both transmitter and receiver, plug in both microphone and earphones, instruct your listeners to place the earphones in their ears, and adjust the volume on both machines until a satisfactory hearing level has been reached.
Follow the same procedure when setting up multi-channel transmitters and receivers, just make sure that the switches on both machines are turned in to the same channel (1, 2, or 3).

Can I talk to two persons at the same time?
Yes, you can talk to two or more persons at the same time, provided each person has a receiver and earphone. Our equipment is also used by tour guides and conference interpreters, who talk to multiple listeners at the same time.

When would you use this equipment?
We use it in trials, hearings, and in all other situations where it is advantageous for the interpreter to get closer to the bench. For example, sometimes it is difficult to hear the DA's closing argument to the jury if you're sitting in the back. Another situation is when you are in Juvenile Court, for example, interpreting for the parents of a minor who are sitting in the audience (in some courts) and distance or noise makes it difficult for you to hear well if you sit next to them.
It is also useful in smaller hearing rooms, when counsel complains that the interpreter talking to his subject makes it more difficult for them to hear each other. This has happened to us during Workers Compensation Board hearings, for example.

What is the difference between single-channel and multiple-channel equipment?
Single-channel transmitters and receivers operate in only one frequency. This can create a situation where two interpreters transmitting in the same frequency in the same building can interfere with each other's transmission. For that reason, large courts who utilize the services of several interpreters at the same time prefer multiple-channel equipment. We offer three-channel equipment in the frequencies of 192-194 MHZ, which permit up to 3 interpreters to use wireless equipment in the same building, even in the same room, without interference. In addition, single-channel equipment is offered in 13 different frequencies, from 72 to 78 MHZ.

In addition, we now offer 16-channel UHF transmitters and receivers. These units allow you to transmit to 16 different listeners at the same time (using a transmitter and receiver for each speaker and listener) without interfering with each other.
These units operate in much higher frequencies (UHF), which provide better range and quality of sound.

Can I use rechargeable batteries?
Yes, you can use niMH rechargeable batteries instead of AAA batteries. niMH batteries come with a capacity of 400 to 1,000 mAh (mAh is a technical term, miliampere/hour, that indicates how much power a battery will hold). The best high-capacity batteries carry ratings of 900 to 1,000 mAh. Keep in mind that rechargeable batteries will self-discharge in around 30 to 60 days, even without using them. We recommend charging these batteries on a regular basis, at least every 30 to 45 days. NiMH rechargeable batteries can last between 500 and 1,000 recharges.
