@Awanish: Thank you for your comment.

Please do check with the maker as it seems to be the problem of settings.

During berthing, it is strictly forbidden for ship’s to test gmdss equipment. It is assumed that the gmdss watch is switched off, mf/hf off, ais/vhf 1 & vhf 2 on low power, both radars on stand by, main aerials isolated prior to enter the harbour with this noticed also in gmdss logbook. The only equipment remain on is inmarsat equipment but no any gmdss test are allowed to be done at berth. The reason to swirch off radio/gmdss equipment when alongside is for tankers vessels at terminal to avoid unnecessary radiation/ or sparks which could lead to accidents such as fire, explosion and so on, and for all types of vessels to avoid jam/interference. we can define a port or harbour a place with high density of vessels, each one carrying its own radio installation, which, if in use all in same time and in such a restricted place, will produce congestion in radio system, not in maritime mobile service only, but for aeronautical, army, police, medical, security, government and other communication systems which use same band of communication. before gmdss system come into force in february 1999, ship’s transmitters where sealed by port authorities (radio inspector) from arrival to departure, even in anchorage hf transmitter was forbiiden to be used, only mf communication with adjacent mf coast station were allowed. on the other hand, gmdss system is designed mostly for distress and safety at sea, in port we don’t need to use it. in case of emergency in port we have other option. So, if you need to test gmdss equipment daily, weekly or monthly, you can do it before arrival or with first opportunity after departure, but not in harbour. in harbour you are dealing with loading/discharging operation as deck officer. For routine/commercial communication ship’s captain have enough email system which cover all his need for communication. and don’t forgeth, the ais is not gmdss equipment. it can be tested, but is not compulsory as part of gmdss requirements. it can be tested only as bridge equipment as required by vetting or psc inspection.
More information regarding gmdss testing daily/weekly/monthly you can find in company policy, gmdss equipment manuals and instuctions, gmdss manual, admirality list of radio signals vol 5 (gmdss) and ITU radio regulations. good luck !
