The Hytera PD7Ex range of radios are market leaders when it comes to a reliable ATEX devices. Built to military standard (MIL-STD-810G), they will continue to work throughout the harshest of environments, IP67 resistance means that both the 795Ex and 715Ex are water and dustproof.
The PD795Ex has a full display and keypad, the radio allows for the user to not only communicate via talking but to also send text messages between devices. The PD715Ex doesn’t have a display or keypad, but you are still able to send text messages, texts can be pre-programmed into the device to be sent on command, these may include specific instructions between teams or a call for help. For verbal communications between radios the device has a channel capacity of 1024, but with mixed mode scanning being a feature on these radios you can hold and scan through both analogue and digital channels.
ATEX radios such as the PD7Ex range are made for working in dangerous environments, these specific radios are fit for purpose within Gas, Mining and Dusty industries (Specifications below). Regular radios can accumulate static which may cause electric arc, this arc could produce a spark via numerous methods such as the battery becoming disengaged, or other maloperation such as being dropped. Such an occurrence could lead to disastrous consequences, which is why an ATEX radio is highly recommended when working in dangerous conditions.

The Hytera PD7Ex series has various safety features readily installed on the device. A function that ties in with this is the GPS tracking, such a feature allows for the whereabouts of the radio to be tracked to a small radius of the actual location of the device. This is extremely important when working in such environments as the ATEX radios are designed for, because at times users of the device could be in high risk working environments. “Man Down” is something which works hand in hand with this. Should a worker be knocked unconscious or trapped with no means of escape, the radio if laid on its side, will send out a distress signal to all other radios connected to its network, with GPS this allows the user to be found quickly and at less risk of serious injury. Other safety features which these devices come readily installed with are Lone Worker, Remote Monitor, Radio Enable/Disable and also a Call Alert.
