H350 Walkie Talkie Cheap Handheld Radio Transceiver is unique for its compact and delicate body, superb sound quality, superior drop protection and ergonomic design. Feature: [Wide Communication Coverage] High transmit power accommodates wide communication coverage up to 5Km in open area. [High quality Audio] The speaker delivers clearer and stronger audio because of improved acoustic mechanics, allowing users to continue communicating even in noisy and harsh conditions. [Rugged and Durable] With rugged and compact design, the H350 is durable enough to withstand 1.5m drop. [Extended Operation Time] An extended life Li-ion battery provides 18hr talk time at a lighter weight, for greater productivity. [High/Low Power Switchable] By simple pressing one button, users can switch to low power when communicating within limited range coverage or switch to high power when further distance is required. High transmit power optimizes range coverage while low transmit power conserves battery consumption, the entire user’s control. [Programmable 12.5 kHz/25kHz channel spacing] The feature enables flexibility and easy migration of channel spacing requirements when the need arises, with no need to buy new radios. [DTMF ANI] [2-Tone CODEC] Each channel can be set up this feature. The feature is automatically remind users by voice and indicator When the radio receive signals. [Monitor] The feature allows users to monitor the activity on the current channel. It is especially helpful for receiving a weak signal. [Battery Save] The battery save feature is automatically activated once no activity on the channel and no operation performed, for extended operation time. [Low Battery Alert] Automatically remind users to recharge when the battery level run low. [Busy channel lockout] A channel already in use is not available to other users. [Time-out Timer] The feature allows for more efficient use of channels by limiting the amount of time of each transmission. [Wired Clone] Easily copy the features of one radio to another. [PC Programmable] You are able to customize the features of each radio for each user. [CTCSS/CDCSS] Set up workgroups/users with unique CDCSS/CTCSS to prevent unwanted conversations on the same frequency. [Selectable Squelch Level (0-9)] Helps minimize interference from undesired weak signals and helps weak signals be heard. [Priority Scan] 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.
