Making a Distress Call

Speak slowly - clearly - calmly.

For future reference, write your boat’s name & call sign here:

1. Make sure your radio is on.

2. On the radio, press the 16/67-Tri button to switch to Channel 16

(156.8 MHz). (If the corner of the display does not show 16, press

the 16/67-Tri button again until it does.)

3. Press the push to talk button and say: “MAYDAY -- MAYDAY --

MAYDAY.”

4. Say “THIS IS {name of your boat (three times) and call sign/boat

registration number (once)}.”

5. Say “MAYDAY {name or call sign of your boat}.”

6. Tell where you are: (what navigational aids or landmarks are near,

or read the latitude and longitude from your GPS).

7. State the nature of your distress, (e.g. are you sinking, medical

emergency, man overboard, on re, adrift, etc.)

8. State the type of assistance you need (medical, towing, pumps,

etc.).

9. Give number of persons aboard and conditions of any injured

persons.

10. Estimate present seaworthiness of your ship (e.g. how immediate is

the danger due to ooding or re or proximity to shore).

11. Briey describe your ship, giving the ship name (e.g. “Blue Duck is

32 foot cabin cruiser, white hull, blue deck house”).

12. Say: “I WILL BE LISTENING ON CHANNEL 16.”

13. End message by saying “THIS IS {name or call sign of your boat},

OVER.”

14. Release the push to talk button and listen.

If you do not get an answer after 30 seconds, repeat your

call, beginning at step 3, above.

Warning

The exclamation point within an equilateral triangle is

intended to alert the user to the presence of important

operating and maintenance (servicing) instructions in the

literature accompanying the appliance.

NOTE

Floating/Waterproof: JIS8

Uniden’s MHS127 radio is designed to meet the water proong standard of

JIS8 and will oat in water.

This Means: Protected against the effects of continuous immersion in water.

The MHS127 can withstand immersion in water up to 1.5m depth for 1hr.

Note this is not suitable for scuba diving.

The MHS127 will only meet this rating if fully assembled

and all rubber seals are well maintained and correctly tted.

This means that the carabiner clip is not connected and the

battery cover securely fastened.

NOTE

After your radio is submerged in water, you might notice that the sound is

distorted. This is because there is still water remaining in and around the

speaker and microphone. Just shake the radio to clear excess water, and the

sound should return to normal.

If your radio is exposed to salt water, clean your radio

thoroughly with fresh water, and dry it before turning it on.
