Question: How easy is it to push the emergency button that automatically sends a mayday and location? I am wondering if it is easy to hit accidentally.
Document: In an emergency you do not have to turn on the radio itself or wait for anything else to happen. Just activate the Distress Call button and go. This is well thought out.
This radio is a great value. In addition to being a radio, it is a self-contained emergency call system. Once you program it with an MMSI number (and you should), you need only press the &#34;distress&#34; button, and the Coast Guard will know (a) who you are, (b) exactly where you are (because of the on-board GPS), and (c) that you need help NOW.
UPDATE:  A test of this feature showed that the Uniden VHF has to be turned on first before the MMSI distress transmission can be sent. Uniden Customer service was incorrect on how this works, but it does work.A call to Uniden Customer service revealed that the Distress Call button turns on the radio, activates the GPS and sends the MMSI codes out, even if the radio is turned off when that button is activated. That is a very useful piece of information and feature on both the MHS135 and MHS235 radios.
It was just what I needed..compact, functional and easy to set up and operate. The use is as a backup to my sailboat's fixed radio and it compliments that perfectly.
Easy to use, but would rather have  hnmore control of volume and squelch. I DON,T plan on getting it wet but I would rather be safeThan sorry it's not weather proof.
The other stuff works fine, and I'm glad to have it. I definitely want the GPS feature for one portable radio. It lets you send out an automatic signal that tells rescuers where you are and who you are by pushing a single button.So, to summarize--Fixed mount radios have more range, up to about 25 miles (or more on a good day) with a good antenna.
This is a well made and well regarded emergency marine radio I hope I never have to use. Its in my emergence canoe touring case if I ever need it.
The unit arrived just fine, but... the battery was dead and would not charge. the charger light just blinked a slow red. I called uniden and after about a 1 hour wait and 1 transfer. a service rep told me it was a bad battery and I should return the unit to amazon. the return process is very easy. I am now awaiting a replacement. I will update this review after I get it and try it out.....
This is a all in one ,I need the weather, there are five all together , and Noah is it. they will give you a weather window for a fishing trips out to thirty nautical miles If you need to get the coast guard go to channel 16, want to get under a low bridge call the dock master. It floats and has a  S.O.S. light that sends when in water.
This is a good handheld VHF radio. I got the expected range and great audio (Remember: It's a handheld - If you need better range install a fixed mount). The memory Scan is nice. It does have SQ. A PDF manual can be downloaded online and it's fairly easy to follow. The radio is easy to use, especially compared to others. The DSC is a must in our harbor. Great accessories for the value. The speaker MIC is not waterproof but the radio is certified.
Answer: You have to hold the button down for a bit. The accidental bump is not long enough.
