Maritime radios are also commonly known as "water full frequency radios" or "marine type radios". The maritime radio is essentially a two way radio, there are handheld walkie-talkies and ship-borne radios(similar to vehicle mounted radio). As a professional VHF marine radio designed for maritime applications, it needs to meet some characteristics of maritime applications.
Channel Group Selection
The transceiver is pre-programmed with 59 U.S.A., 59 international and 63 Canadian channels. These channle groups may be specified for the operating area.
Channel Selection
1.Channel 16
Channel 16 is the distress and safety channel. It is used for establishing initial contact with a station and for emergency communication. Channel 16 is monitored during both Dual-watch and Tri-watch. While standing by, you must monitor Channel 16.
2.Channel 9
Each regular channel group has a separate leisure-use call channel(Channel 9; default). The call channel is monitored during Tri-watch.
Caution
- Never use the Distress call when your ship or a person is not in an emergency
- Do not use or place the transceiver in areas with hear, humidity and dust.
- The working voltage for the transceiver is 13.8V. If the power source is 24V, please use a power converter(24V convert to 13.8V), or the transceiver won't work.
- Never directly connect to AC220V, this will ruin the transceiver if an abnormal odor or smoke is detected coming from the transceiver, turn off the power immediately.
- Do not transmit before connecting the antenna, this will ruin the transceiver.
