I. Product Overview
This product is the Timekettle Wireless Translation Guide System, consisting of three components:
a Timekettle Fluentalk Translator, a Wireless Bluetooth Transmitter,
and Bluetooth Earphones. The three devices are interconnected via Bluetooth to enable
real-time translation and wireless guided tour functionality.
The guide speaks into the translator, which performs real-time translation and transmits the audio
via Bluetooth to the transmitter. The transmitter then broadcasts the signal wirelessly to all earphones,
allowing listeners to receive the translated audio content through their earphones.
This system is suitable for various cross-language communication scenarios including tourism, conferences,
training sessions, VIP reception, and museum/exhibition guided tours.

Tip: After successful pairing, the devices will automatically reconnect next time
(the transmitter must be turned on first). If the earphone channel has not changed, re-pairing is not required.
