DESIGN

More than a smartphone, the Hytera PNC 370 looks like a walkie talkie, quite light and of great ergonomics. It looks like those tactical communication devices, which we see in the movies. It looks robust, resistant.

On the front we find the screen, which is small (remember that it is not touch and less a smartphone), because what you are looking for is only to facilitate navigation between functions. It has two selection buttons and a central key that reminds me of the old ‘Navi’ key that Nokia brought.

The Hytera PNC370 has a very compact design.  Above the small screen there is an LED indicator light.  (Photo: Bruno Ortiz B.)

Then a wheel for navigation, buttons to answer and turn on the flashlight [verde], hang up and turn on / off the equipment [rojo], and two more buttons that are programmable, for emergency contacts. On the lower front is the speaker and a small microphone.

On the right edge are -covered with rubber covers- the headphone jack and the input for the micro USB cable (used for charging). On the left side is the PTT button (orange) and below the volume control buttons. On the bottom edge are the contacts for the multi-charger base.

On the back we have a rough cover that can be removed, to remove the battery (and place the micro SIM). In addition, there are two small screws to attach the accessory with the belt clip. On the back of the antenna you find a small lens that amplifies the light from the flashlight.

WHAT DOES HE DO?

The Hytera PNC370 PoC is a device for those tasks where the communication it’s the last thing to miss. It works as a radio communication device, but it also works over 2G, 3G, 4G (LTE) and Wi-Fi networks. Critical communications, they are told.

That means that, although it works on Android, you do not have the Google Play Store or access to any other application store. Applications are downloaded directly.

The interesting thing is that it allows you to communicate from anywhere, thanks to its compatibility with the different cellular technologies available. And when you are not accessible, you can use a Wi-Fi network to establish communication.

The back of the Hytera PNC370 features a removable cover.  The two screws on the back are used to place a clip that allows it to be worn on the belt.  (Photo: Bruno Ortiz B.)

It allows communication by user groups and location does not matter. You can even be in another country and if you are connected to the Internet through Wi-Fi, you can receive calls without any problem, even if you do not have data on your SIM. Communication can be done in two ways: with regular calls or through short messages, using the PTT button. This type of communication is useful when you have to send reports, give or receive direct directions. In both cases, the quality is very good.

To all this, Hytera’s own PNC370 PoC design and characteristics are added, which make it clear that it is one more work tool.

Regarding autonomy, the device promises up to 18 hours of useful life. Its 3,100 mAh battery can be recharged using the micro USB cable or through a multi-charging station.
