Okayo OTG-102 Transmitter

One-way, digital UHF tour guide transmitter. 823 MHz ~ 832 MHz + 863 MHz ~ 865 MHz, 42 channels. Two transmitters can broadcast on the same channel. Range up to 100 meters line-of-sight. Powered by 2x AA batteries. Transmitter operating time is approx. 16 h.

The Okayo OTG-102 mGuideⓇ (US ready), launched in 2022, is undoubtedly the most modern digital tour guiding system from Okayo Electronics, and likely the most advanced tour guide system among all tourist models. The model sold by Mexpo includes additional features specially prepared for our customers.

1 Set – 2 Continents

OTG-102 receivers can legally operate in both Europe and the United States. Simply purchase an additional transmitter for the American band and switch the range on the receivers. That’s all. There’s no need to buy separate sets for tours traveling overseas.

Simple System – Amazing Capabilities

Additionally, the Okayo OTG-102 tour guide system is equipped with the following features:

• Simultaneous broadcasting from two transmitters on the same channel (for up to 1 group). This allows, for example, both a guide and a tour leader to communicate with the group simultaneously.
• Group counting – checking the number of receivers within the transmitter’s transmission range – in other words, the guide no longer even needs to see everyone to count the group and
• check if anyone is missing.
• Remote alarm triggering (sound and vibration) to, for example, get the group’s attention or announce the end of a break during a tour.
• Range alarm – the receiver will notify the user when they start to move out of the transmitter’s range.

Break in narration? Play some music!

The transmitter has an additional 3.5mm TRS Aux-in jack for connecting an external audio source, such as a smartphone or MP3 player. This allows you to play music or a pre-recorded audio guide during breaks.

Tour guiding has never been so energy-efficient…

OTG-102 receivers feature the longest operating time in their class on a single power source (over 40 hours) and can operate on either two or just one AA battery or rechargeable battery.

Universally Designed

The OTG-102 system was designed with people with disabilities (PWD) in mind. The high-contrast OLED display on the transmitter provides better readability for visually impaired individuals. The headphone jack with HAC (Hearing-Aid-Compatible) option on the receivers ensures that connected headphones work with hearing aids. Dedicated buttons allow for simple and intuitive use of the devices.

Along with the OTG-102 system, we offer a wide selection of accessories such as microphones, headphones, chargers, and transport bags and cases.
