Motorola XiR P3688 Handheld Radio | MOTOTRBO DMR Digital/Analog Two‑Way Radio
The Motorola MOTOTRBO XiR P3688 is a professional DMR digital two‑way radio built for clear communication and dependable day‑to‑day operation. Supporting digital and analog (configuration dependent), it’s ideal for security, facilities, events, warehouses, and team coordination where fast push‑to‑talk and consistent audio matter.
Main features
Digital and analog dual-mode operation
Motorola XiR P3688 digital walkie-talkie has analog and DMR digital dual-mode operation functions. Many companies or teams are in the transition stage from analog communication to digital communication, and may face the complex situation of coexistence of new and old equipment and mixed communication networks. XiR P3688 can seamlessly adapt to these two modes to ensure stable connection in different communication environments.
Advanced TDMA technology
The use of TDMA (time division multiple access) technology is a highlight of XiR P3688. TDMA technology divides a radio frequency into multiple time slices, allowing different communications to be carried out in their respective allocated time slices, thereby achieving one frequency to support multiple communications.
Long battery life
XiR P3688 has excellent long battery life, up to 19 hours in low power mode and 14 hours in high power mode. This is crucial for industries that require long-term continuous work.
Excellent voice quality
With Motorola’s Companding technology, XiR P3688 can provide clear and loud voice quality. In noisy environments, such as steel mill workshops, the operation noise of machinery and equipment is relatively high, and communication between workers needs to overcome noise interference. CompandingTM technology effectively reduces the impact of background noise on voice signals through special voice compression and expansion processing, so that even in such a high-noise environment, the receiver can clearly hear the content of the call, accurately understand the instructions and information, and avoid communication errors or safety accidents caused by unclear hearing.
Humanized design and ruggedness
The design of XiR P3688 fully embodies the humanized concept and conforms to ergonomic principles. At the same time, the walkie-talkie also has a rugged and durable quality, passing the ALT five-year accelerated aging test and the US military standard test. In harsh environments such as mining, equipment often needs to face the test of various adverse factors such as dust, vibration, and humidity. The sturdy shell of XiR P3688 can effectively resist the erosion of these external factors, ensuring that it still maintains good performance under long-term and high-intensity working conditions.
Accessory sharing
XiR P3688 can share accessories such as batteries and chargers with GP3688 analog walkie-talkies. For those who already use GP3688, this accessory compatibility greatly reduces the cost of their conversion from analog to digital communications.
