Our HT649 intrinsically safe ATEX approved GMDSS portable, is MED certified and carries the essential Wheel Mark logo. For those requiring a full featured intrinsically safe GMDSS portable, with high visibility back-lit LCD, the HT949 is the most advanced GMDSS portable available From an established generation of commercial grade products the HT Series 2.0 is designed to endure any emergency situation in the most hostile marine environment. Not just compliant with MIL-STD 810C/D/E/F, the HT Series GMDSS also exceeds the MED's IP67 submersibility requirement (1m - 30 minutes). Our GMDSS portables are uniquely approved to IP68 (5m - 1 hour) Entel is the first manufacturer to offer a solution to ship owners who, quite rightly, have been demanding an intrinsically safe approved GMDSS portable for their hazardous cargo vessels. It is mandatory, by law, for hazardous cargo vessels to use intrinsically safe radios. Why should their GMDSS portables be any different?  Technical Characteristics Frequency Range 156 - 163.275MHz (HT949) Channels INT, USA, CAN  Channel Spacing 12.5 kHz / 25 kHz Communication Method Simplex / semi duplex Antenna Impedance 50 ohm Antenna Whip / stubby Battery Type  1800 mAh Li-Ion battery pack Power Supply Voltage 7.4V DC Current Drain (nominal)  TBA Duty Cycle (5/5/90) TBA Microphone Internal condenser microphone Operating Temperature -20° to +55° Size (mm)  59.5(W) x 130(H) x 37(D) W = 59.5  (62 including protrusions) H = 130 (145 inc knobs) D = 37mm (41 including battery protrusions)   Weight 277g with battery and aerial    Power Output HIGH – 5W, LOW - 1W Modulation 8K0F3E/16K0F3E Oscillator Method PLL Frequency Stability < ±0.00025% (±2PPM) Maximum Deviation ±2.5 kHz(Narrow)/ ±5 kHz(Wide) Audio Distortion < 5% (1 kHz 60%) Spurious Emission -68 [dBc] Hum & Noise -40 [dB]   Receiver Type Double Super Heterodyne type Sensitivity -0.25uV (12dB SINAD) Frequency Stability ±0.00025%(±2PPM) Spurious Rejection -60 dB Adjacent Channel Selectivity -60 dB (Narrow) , -70 dB (Wide) Distortion < 3% Typical  Hum & Noise -40 dB Audio Output 1W Speaker Size 38 mm Entel is the first manufacturer to offer the superior IP68 specification, whereby we ourselves determine at what depth and for how long our equipment must remain waterproof. Not content with just the standard IP67 entry-level (1 metre for 30 minutes) Entel's IP68 HT series is certified as waterproof-submersible to an unprecedented depth of 5 metres for 60 minutes. Aware that the smallest tolerances of case size and material variation alone could compromise your radio's waterproof integrity, uniquely, each individual Entel portable is tested on a custom-built air pressure test-jig to ensure it meets the exacting high standards we have set for ourselves.
