Yes, the Standard Horizon HX870 can receive NOAA weather alerts when tuned to a weather channel or the last selected weather channel during scanning modes or while on another channel. When an alert is received, the transceiver stops scanning and emits a loud beep to notify the user.
The HX870 is equipped with the E2O (Easy-To-Operate) system. Basic opera- tion may be accomplished by following the procedure below: POWER: Press and hold to turn on/off the transceiver. PTT (Push-To-Talk): Activates the transmitter when pressed.
(800) 767-2450. We appreciate your purchase of the HX870, and encourage you to read this manual thoroughly, so as to learn and fully understand the capabilities of the HX870.
The HX870 is capable of DSC (Digital Selective Calling) ITU Class D operation. Class D operation allows continuous receiving of Digital Selective Calling func- tions on channel 70 even if the radio is receiving a call. The HX870 operates on all currently-allocated marine channels which are switchable for use with USA, International, or Canadian regulations.

NOTE The HX870 has the DSC Distress calling, that can transmit a distress call digitally to all ships with compatible DSC radios. Refer to section “10 DIGITAL SELECTIVE CALLING (DSC)”. CALLING ANOTHER VESSEL (CHANNEL 16 OR 9) Channel 16 may be used for initial contact (hailing) with another vessel.
However, in certain situations it may be necessary to temporarily use a higher power. See Page xx for means to temporarily override the low-power limit on these two channels. HX870 Page 11...
