The Motorola TLK 25 redefines professional communications in environments where style, low weight, and discretion are essential. Purpose-built for retail, hospitality, healthcare, and facility management, it eliminates the bulk of traditional two-way radios and smartphones.

Frontline staff can switch talkgroups, check device status, or send messages hands-free without looking down at a screen. Despite its compact form factor, the TLK 25 includes a comprehensive safety suite featuring a dedicated emergency button, an accelerometer for fall alert detection, and lone worker monitoring to ensure immediate response during critical incidents.
The TLK 25 is designed for frontline workers requiring a lightweight, easy-to-use communication device. Ideal for sectors including:
Retail & Supermarkets: rapid customer service response and inventory coordination
Hospitality, Dining & Events: discreet staff coordination across housekeeping, front desk, and event teams
