H350 Hiyunton Handheld Two-way Radio

H350 Hiyunton Walkie talkie/Two Way Radio Handheld Transceiver, which supported the 14th Asian Sailing Championships and the 16th Asian Games successfully. High transmit power accommodates wide communication coverage up to 5Km in open area. The speaker delivers clearer and stronger audio because of improved acoustic mechanics, allowing users to continue communicating even in noisy and harsh conditions. With rugged and compact design, the H350A is durable enough to withstand 1.5m drop. It is especially helpful for receiving a weak signal. Automatically remind users to recharge when the battery level run low. A channel already in use is not available to other users. The feature allows for more efficient use of channels by limiting the amount of time of each transmission. You are able to customize the features of each radio for each user. Set up workgroups/users with unique CDCSS/CTCSS to prevent unwanted conversations on the same frequency. Helps minimize interference from undesired weak signals and helps weak signals be heard. Select one channel in the scan list as the priority channel. When scanning remains on a non-priority channel, the radio continues to monitor activities on the priority channel, and jumps to the priority channel if activity is detected.
