2.0 INTRODUCTION 2.1 THIS MANUAL 2.1.1 This manual contains necessary information for the operation, maintenance and performance of distress communications utilizing the ACR/2727 Survival Craft Portable Two-Way Radiotelephone. The user is strongly recommended to read this manual in its entirety. A photocopy of the suggested procedures for distress communications outlined in section 7.
All controls (except the ON/OFF switch) are flat panel push types located on the front surface of the radio (see Figure 2, Control Panel). ON/OFF Slide up to turn ON, and slide down to turn OFF. VOLUME s Increases audio output level to maximum. VOLUME t Decreases audio output level. PTT Push To Talk activates transmitter while switch is depressed. When switch is released, radio returns to receive mode automatically. (Also refreshes channel display for 1 second.
4.1 To activate the unit.1 To activate the unit: a) b) c) d) 4.2 Locate slide switch on upper right side of unit (Figure 1). Using thumb, push slide switch up to ON position. Front panel will illuminate and noise will be heard coming from speaker. After 3 seconds, automatic squelch will mute the noise. To turn unit off, push slide switch down to OFF position. To select a channel.
3) Weather channels — The display consists of a “-” followed by the single-digit channel number. For WX10, the display shows -0. The display is lighted for five (5) seconds after the channel is selected, then is blanked. g) To restore the channel display, press PTT briefly. LEDs will show current channel number for one (1) second (simplex/duplex channels — channel numbers for ½ second followed by an “A” for ½ second). 4.3 To receive a channel and set volume.
The Survival Radio and its protective cover shall be packed with the ship's survival craft or in a survival suit. When not packed with a life raft, the radiotelephone should be stored in an accessible place, as close to the survival craft as possible. 5.2 MANDATORY TESTING .2 MANDATORY TESTING 5.2.1 Radiotelephones operated within the U.S.A. must be operationally tested on a periodic basis (FCC regulations, part 80, section 80.834, until superseded by section 80.1095).
k. Press the CHANNEL t key to tune unit to any channel (except Channel 16). l. Set the monitoring transceiver to the same frequency. (See Table 4.1 for operating frequencies.) m. Listen for any activity. n. If no activity is detected, transmit the test message and have someone monitor the transmission (see above for suggested test message formats.) o. If the test signal was not heard (full quieting), have the unit inspected at your nearest authorized service center. p.

The Survival Radio is supplied with a replaceable lithium battery pack. This primary battery pack will operate the radio for at least 8 hours, in compliance with IMO/SOLAS and FCC requirements for a survival craft radio. To maintain compliance with these regulations, the lithium battery pack must be replaced after 5 years or after any use (with the exception of activating the unit for the purpose of testing.
2. The commonly used pronunciation in English speaking countries MAYDAY pronounced phonetically as “ ma - d a . ” To prevent the distress signal from being misunderstood, and to improve the intelligibility of the distress call, use the two pronunciations above when calling, for example (also, see example for part c): “M’AIDER MAYDAY M’AIDER THIS IS MARY JANE WXT599 WXT599 WXT599.” c. Always use the ICAO Convention (Convention on International Civil Aviation) recognized alphabet for spelling.
Because of the above fact, and to maximize the range of the survival craft VHF radiotelephone, the unit should be held as high as possible without endangering the safety of the operator.
