Principal key functions are performed using a keyboard array mounted on the front panel. The operator is guided by 128x32 LCD graphics display. The display has adjustable backlighting, allowing

maintenance of night vision or high levels of luminescence in poor visibility. Network station addresses and radio numbers are stored in easily accessible address books and as little as two key strokes will initiate a call. ■[Extended operation time]-The low current consumption of the GR-310 radio enables it to operate for over 20 hours on one battery pack. Spare quick change battery packs are small and lightweight. The battery packs contains the charger management system and can be charged when connected to the radio or separately with charger including grid charger, solar charger. ■[SATCOM function]- The GR-310 supports military tactical Satcom functionality, so it makes possible to communicate in beyond horizon condition. It is possible to communicate in worldwide in anytime, anywhere. ■[Digital Encryption and scrambling]-The GR-310 can be fitted with a variety of scrambling and digital encryption functions for voice and data security. The GR-310 includes secure calling(an innovative narrow band voice scrambler providing secure point to point or point to multipoint communication), AES 256 bit digital encryption assuring secure voice and data operation ■[Frequency Hopping]-The unique, easy to use frequency hopping function requires no central synchronization station, has short entry or late entry time delay and requires no hopping handshakes. Hopping rate of 10 hops per second, using 25 digit hopping encryption key, and user selectable hopping bandwidth to suit the antenna type in use, the system provides excellent protection against Electronic Warfare (EW) attacks.
