vhf intercom maintenance

VHF walkie-talkies and two-way wireless phones are important equipment for ship communication and require regular inspection and maintenance to ensure their normal operation.

Check the power and status of the battery every day and replace or charge it in time

Check the connection and fixation of the antenna every day to avoid looseness or damage

Check the appearance and keys of the device every day, remove dust and dirt, and prevent moisture and corrosion

Check the transmitting power and receiving sensitivity of the device monthly, using test batteries or special instruments for testing

Check your equipment's Digital Selective Calling (DSC) functionality annually to ensure it is sending and receiving distress signals correctly.

Calibrate and repair the equipment regularly according to the manufacturer's instructions, or entrust professionals to perform services.

In addition, when using VHF walkie-talkies and two-way wireless phones, the following principles should also be observed:

Distress calls or messages have absolute priority, all other transmissions should stop and remain listening

Listen to make sure the channel is not occupied before communicating to avoid unnecessary communication interference.

Speak concisely and try to shorten the time of each launch

Communication should be carried out on the channel marked by the shore station, and communication instructions issued by the shore station should be obeyed.

Any ship sailing must remain on duty and listen to DSC70 channel and VHF16 channel continuously.
