Review: Awesome sets for simultaneous translation or live tours. Tip- Check for local fm intereference - More than enough for light use, like interpreting at a wedding or church, doing a driving tour for guests. These worked flawlessly for live interpretation. The Lock feature helps users not chang frequencies, and neck strap is actually useful. Clear transmission within 15 feet as long as there are no obstructions or competing frequencies. At first out of the box we were disappointed with the hiss and static even at close range, but eventually we figured out how to get clear sound: 1) switch from stereo to mono; this made the most improvement and eliminated hiss 2) search for open frequencies. The default is 107.5, and our area is saturated at the higher fm stations, so we researched our local fm interference and reset to the bottom ranges and found a space where nothing was competing 4) make sure the venue isn’t also using fm for other mics. If so, find the band they use and avoid it.

**Q: Approximately how long do the batteries last on the receivers?**
A: Dear customer,
Thanks for your question.
For PR13 FM Receivers, it uses 2 x AAA batteries, but it not included in the package. The lasting time of the battery usually depends on the capacity and the quality of the battery. 
And the different volume will also affects the lasting time. You can divide the capacity of battery by 50MA to calculate the lasting time of the battery.

### ⭐⭐⭐⭐ Great Buy
*by G***N on August 20, 2025*

The Retekess Church Translation System works great for our needs. The transmitter charges in just 20 minutes, which is super convenient, and the receivers last about 6 hours on a single set of batteries. The sound is clear, and the setup is simple for both small and large groups. Very reliable for church services, tours, or classroom use. Highly recommend!
