Canceling an automatic distress call

While the radio is waiting for a response, it gives you the option of canceling the call. To cancel the distress call, choose Exit and press CLR/SCAN.

Receiving a DSC call

If your radio receives an individual DSC call from another station, it sounds an incoming call tone and displays the name/MSI number of the station calling you. To respond to the call, select Send: Able-Comply; the radio sends an acknowledgement and automatically switches to the designated response channel. To reject the call, select Send: Unable- Comply; the radio advises the other station that you are unable to respond to the call.

If the DSC request contains a response channel that you are not allowed to use, the radio displays Not Support CH; your only response option is Send: Unable-Comply.

If the radio receives a group or all ships call, it sounds an incoming call tone and automatically switches to the designated response channel.

Receive log

Just like your telephone’s caller ID list, your radio keeps track of the calls you receive but do not answer. The receive log is useful if you have been off your boat or away from your radio and want to see who has tried to contact you. The radio displays the last 10 distress calls and the last 50 non-distress calls that it received. If you have unread incoming DSC calls, the radio displays a Message icon. When you display all Distress and Other receiving logs, the message icon disappears.

This robust design ensures that the radio remains operational even in adverse weather conditions, providing peace of mind to users.

Another notable characteristic of the MHS135DSC is its built-in GPS receiver. This feature allows users to easily access their location and navigate more effectively. The unit can display real-time coordinates, and it integrates seamlessly with other marine navigation systems. The internal GPS also facilitates DSC operations, ensuring that crucial location data is sent during distress calls.

The MHS135DSC operates on both the VHF marine radio band and supports a wide range of channels for effective communication. With 1W/5W power settings, users can adjust transmission strength according to their communication needs, whether they are in close proximity to other vessels or need to reach distant stations.

A user-friendly interface is an additional asset of this radio. The clearly labeled buttons and intuitive design make it easy to operate, even for those new to marine electronics. The radio also features a bright LCD display for clear visibility even under direct sunlight.

Battery life is another critical aspect, and the MHS135DSC excels in this area with a rechargeable lithium-ion battery that provides long-lasting power. The device also supports battery save modes, ensuring that the radio remains functional during extended outings.

In summary, the Uniden MHS135DSC is a feature-rich handheld marine radio that prioritizes safety, usability, and durability.
