The Retekess T117 is a wireless service call button for restaurants, hotels, healthcare environments, and other service venues. When pressed, the T117 transmits a call signal to a compatible receiver, alerting staff to the customer's request.

This listing contains 5 × T117 call buttons only. A compatible Retekess receiver is required and is sold separately.

Key Features

• Four service call functions — CALL, ORDER, PAY, and CANCEL; customers select the type of assistance needed directly from the table or counter
• 433 MHz wireless, ASK (AM) modulation with learning-code encoding — encoded signal reduces false triggers from other 433 MHz devices in the environment
• Open-area range — up to 200 m in open areas (manufacturer reference figure); actual range will be reduced by walls, metal structures, and interference
• Long battery life — powered by 2 × CR2016 coin-cell batteries (installed, user-replaceable); 17 mA working current; manufacturer-rated battery life approximately 6–12 months depending on usage frequency
• Everyday service durability — ABS housing; Retekess describes the housing as resistant to water and oil exposure, but no formal IP rating is specified
• Easy installation — adhesive mounting sticker included with each button for wall or table mounting; four-section housing allows straightforward battery replacement

Compatible Receivers

The T117 call button is compatible with the following Retekess receivers, sold separately:

• Retekess T128 watch receiver

Compatibility is specific to these models. Do not assume compatibility with other Retekess receivers based solely on shared frequency.
