INTRINSICALLY SAFE Submersible 5 Watt Commercial Grade HX400IS Handheld VHF with LMR Channels

Intrinsically Safe
The submersible HX400IS intrinsically safe handheld VHF is built to withstand the day-in day-out punishment in hostile commercial environments. The HX400IS, SBR-29LIIS Intrinsically Safe battery pack, and optional SSM-14A and CMP460 speaker microphones all meet ANSI/UL 913-5th Ed. requirements for: Class I: Flammable Gases, Vapors, or Liquids Div. 1 Group C (Ethylene), Group D (Propane), Class II: Combustible Dusts, Div. 1 Group E (Metals), Group F (Coal), Group G (Grain), Class III: Ignitable Fibers & Flyings, Temperature Code: T3.
Lithium-ion battery and charger
The HX400IS is supplied with a whopping 3200 mAh Lithium-Ion battery that will keep you talking for about 18 hours. There is no need to worry about the time it takes to fully charge the huge 3200mA battery as the HX400IS is supplied with a 3-hour rapid charger.
Marine and Land Mobile Channels
The HX400IS is factory programmed with all USA, Canadian and International and NOAA Weather channels. It also has the capability to be programmed with 40 Land Mobile Radio (137-174MHz) channels with CTCSS or DCS signaling by a Standard Horizon dealer. Note: These channels do require the appropriate Federal Communications Communication license.
Built-in Noise Canceling Mic and Voice scrambler
The HX400IS will surpass your voice transmissions expectations in noisy and windy environments with the built-in noise canceling microphone. No need to purchase an optional voice scrambler for secure communications as the HX400IS has it built-in. The internal scrambler is compatible with Standard Horizon VHF Fixed Mount and Handheld VHF 4-code scramblers.
Loud speaker audio
The HX400IS is designed to be heard in even the noisiest environments with 700mW of power supplied to the internal speaker.
Speaker Microphone Connection
Optional speaker microphone or headsets are available to assist with your communications needs.
Programmable Channel Names
The HX400IS is supplied from the factory preloaded with description of the use of Marine channels (16-Distress, 22A-USCG, 71-Pleasure). The channel names may be customized by the user to easily understand the use of each channel.
NOAA Weather channels and Weather Alert
10 NOAA and Canadian Weather channels are pre-programmed and easily selectable using the dedicated WX key. In addition, the HX400IS can be set to monitor WX channels and provide an audible alert to inform of pending storm advisories.
Programmable Scan, Priority Scan and Dual Watch
Scanning is not an issue with the HX400IS. The radio can be setup to scan any number of channels with or without a priority channel or simply can be setup to scan between a priority channel and on other channel (dual watch).
10 favorite channel recall – Preset Key
Dedicated key that allows programming and quick selection of up to 10 favorite Marine VHF or NOAA Weather channels.
