IN CASE OF EMERGENCY INSTALLATION NOTE If your vessel requires assistance, contact other vessels and the Coast Guard by sending a Distress call on Channel 16. The installation of this equipment should be made in such a manner as to respect the EC recommended electromagnetic field exposure limits (1999/519/EC). USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. “MAYDAY MAYDAY MAYDAY.” 2. “THIS IS ...............” (name of vessel). 3.
PRECAUTIONS RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock. RWARNING! NEVER connect the transceiver to a power source of more than 16 V DC or use reverse polarity. This will ruin the transceiver. RWARNING! NEVER cut the DC power cable between the DC plug at the back of the transceiver and fuse holder. If an incorrect connection is made after cutting, the transceiver may be damaged.

8 MENU SCREEN OPERATION ■■Radio Settings items DDScan type (Default: Priority Scan) The transceiver has two scan types; Normal scan and Priority scan. A Normal scan searches all Favorite channels in the selected channel group. A Priority scan sequentially searches all Favorite channels, while monitoring Channel 16. DDScan resume timer (Default: OFF) The scan resume timer can be selected as a pause (OFF) or timer scan (ON). When OFF is selected, the scan pauses until the signal disappears.
MENU SCREEN OPERATION ■■Configuration items DDBacklight (Default: 7) The function display and keys can be backlit for better visibility under low light conditions. The backlight can be set to 7 levels and OFF. DDDisplay contrast (Default: 5) This item adjusts the contrast of the LCD in 8 steps. Level 1 is the lowest contrast, and level 8 is the highest contrast. DDKey Assignment Desired functions can be assigned to Dial and the softkeys.
8 MENU SCREEN OPERATION rrPush [EXIT] to exit the Menu screen. • Push [CLEAR] or [BACK] to return to the previous screen. • Dial assignment The Audio volume (VOL), squelch (SQL), channel selection (CHAN) and LCD backlight level (Backlight) functions can be assigned to any one of 4 sequential positions on Dial. Pushing Dial 1 to 4 times sequentially selects the desired function, and rotating Dial adjusts the level or selects a value or number.
MENU SCREEN OPERATION DDInactivity Timer Set the inactivity timer to between 1 and 10 minutes (in 1 minute steps) or OFF for the “Not DSC Related” item, and set to between 1 and 15 minutes (in 1 minute steps) or OFF for the “DSC Related” item. qq When the “INACTIVITY TIMER” screen is displayed, rotate Dial or push [∫]/[√] to select “Not DSC Related” or “DSC Related,” and then push [ENT]. ww Rotate Dial or push [∫]/[√] to select the option, and then push [ENT] to set it.
9 CONNECTIONS AND MAINTENANCE ■■Connections Green: Listener B (Data-L) Connects to an NMEA Out Negative line of a GPS receiver for position data. q t r w e q ANTENNA CONNECTOR Connects to a marine VHF antenna cable’s PL-259 connector. CAUTION: Transmitting without an antenna may damage the transceiver. w NMEA IN/OUT LEADS Brown: Talker B (Data-L) Connects to an NMEA In Negative line of a PC or NMEA0183 ver. 3.
CONNECTIONS AND MAINTENANCE r DC POWER CONNECTOR Connects to a 13.8 V DC power source. CAUTION: After connecting the DC power cable, NMEA leads or external speaker leads, cover the connector and leads with an adhesive tape, as shown below, to prevent water seeping into the connection. Rubber vulcanizing tape DDConnect to the MA-500TR Connect the transceiver to the high-density D-Sub 15-pin connector of the MA-500TR using the OPC-2014* cable.
9 CONNECTIONS AND MAINTENANCE ■■Antenna ■■Supplied accessories A key element in the performance of any communication system is the antenna. Ask your dealer about antennas and the best place to mount them. ■■Fuse replacement One fuse is installed in the supplied DC power cable. If the fuse blows or the transceiver stops functioning, track down the source of the problem, repair it, and replace the damaged fuse with a new one of the proper rating.
CONNECTIONS AND MAINTENANCE 9 ■■Mounting the transceiver DDUsing the supplied mounting bracket The universal mounting bracket supplied with your transceiver allows overhead or dashboard mounting. • OVERHEAD MOUNTING qq Mount the bracket securely to a surface which is more than 10 mm thick and can support more than 5 kg using the 2 supplied screws (5 × 20 mm). wwAttach the transceiver to the bracket so that the face of the transceiver is at 90° to your line of sight when operating it.
9 CONNECTIONS AND MAINTENANCE ■■MB-132 installation An optional MB-132 flush mount is available for mounting the transceiver to a flat surface, such as an instrument panel. ee Attach the clamps on either side of the transceiver with 2 M5 × 8 mm supplied bolts. • Make sure that the clamps align parallel to the transceiver body. KEEP the transceiver and microphone at least 1 meter away from your vessel’s magnetic navigation compass.
