    StayConnected-0x20 Flexible Deployment

    The innovative structural design gives the HR655 an unprecedented appearance and lightweight performance. With the compact body and built-in duplexer, the HR655 greatly conserves space. With tailored installation accessories, flexible installation can be achieved on sites with challenging space availability. Site installation is possible as long as there is a wall or flat surface. For indoor coverage, the super slim size of the HR655 minimises the requirements for the site and provides trustworthy voice and data communications as well as offering unlimited connections on each floor which are the keys to achieving your business success.

    Designed to operate on an AC power source or an optional battery, the HR655 can keep running in the event of a power outage. When it connects to the AC power supply, the battery works as a backup. In case of an outage, the 12.5Ah battery is ready to power the HR655 for up to nine hours of backup time. This power backup solution reduces the capital investment and maintenance for adding UPS power equipment.

    Created with Sketch. Smooth Transition

    The HR655 can operate in analogue mode, DMR mode, or dynamic mixed digital/analogue mode, which automatically switches between analogue and digital based on the call it receives. The HR655 can ensure that your original analogue radio continues to be connected to the DMR network and protect your legacy system investment to the greatest extent.

    Ergo-20x20 Convenient Management

    Thanks to the Extended Network Management System (XNMS), you can remotely monitor the operation status and alarms of the HR655 in real time, or update the configuration in minutes. This dramatically reduces the time and resources required to maintain various, dispersed repeaters.

    Created with Sketch. Long Battery Life

    The HR655 can be equipped with a 12.5Ah large-capacity battery for use in outdoor scenarios, which can provide up to 9 hours of power supply under the RF power output of 10W. Even if the device is used at 50% duty cycle at 25W full power, the HR655 can still guarantee 4 hours of uninterrupted work protection, providing you with a lasting, uninterrupted communication guarantee.
