Use the included template to cut the installation opening.2. Check the dashboard opening size by sliding the radio into it. If the opening is not large enough, carefully cut or file as necessary until the radio slides into the opening. Check that there will be sufficient space behind the dashboard for the radio chassis.3. Place the radio in front of the dashboard opening so the wiring can be brought through the opening.4. Follow the wiring diagram carefully and make certain all connections are secure to ensure proper operation. 5. After completing the wiring connections, turn the unit on to confirm operation (vehicle accessory switch must be on). If the unit does not operate, recheck all wiring until the problem is corrected. Once proper operation is achieved, turn the accessory switch off and proceed with final mounting of the chassis.6. Carefully slide the radio into the opening, making sure it is right-side-up.7. Secure the radio to the dashboard using #6 panhead screws (not provided).8. Replace the covers on either side of the radio.9. Test radio operation by referring to the operating instructions for the unit.Removing the UnitTo remove the radio after front mount installation, remove the covers, unscrew the installation screws and pull the radio out.Reconnect BatteryWhen wiring is complete, reconnect the battery negative terminal.Bracket MountThe VOSHD4MNT (sold separately) is a versatile mounting base/bracket for easy installation on most flat surfaces. Please use the included M4 screws to attach the radio to the bracket, as shown in the diagram below.NOTE: Use only the M4 x 7-10mm length screws, included.

JHD40BT8WEATHER BAND OPERATIONAccessing the Weather BandPress the MODE button (4) to access the weather band mode.What is the NOAA Weather Radio?NOAA is a nationwide system that broadcasts local weather emergency information 24 hours a day. The U.S. network has more than 530 stations covering the 50 states, as well as the adjacent coastal waters, Puerto Rico, the U.S. Virgin Islands and the U.S. Pacific Territories. Each local area has its own transmitting station and there are a total of seven broadcasting frequencies used: 162.400MHz (CH2), 162.425MHz (CH4), 162.450MHz (CH5), 162.475MHz (CH3), 162.500MHz (CH6), 162.525MHz (CH7) and 162.550MHz (CH1).How many stations can I expect to receive?Since the broadcasts pertain to local weather and information, the transmission power is usually very low (much less than AM or FM stations) which means you will usually receive only one station unless you are on the edge of two or more broadcast signals. The most you will receive is two or three, and that is rare.Is it possible I won't receive any stations?Depending on location, it’s possible to receive a very weak signal or none at all. Also, similar to AM and FM signals, weather band signals are subject to surrounding conditions, weather, obstructions of the signal by hills or mountains, etc. If no NOAA signals are found/received, the “NO SIG” icon will flash in the display and the tuner will scan all seven NOAA frequencies every 30 seconds.How will I know I am tuned to the weather band?When you select the weather band, the “WB” icon will appear on the display panel, along with the current channel indication. Press the SEEK/TUNE/TRK |<< or >>| buttons (13, 14) to tune to each of the seven channels until you find the weather band station broadcasting in your area.NOAA Weather AlertThe Weather Alert function adds an additional level of user safety by automatically switching from the current function mode to weather band mode for a minimum of 60 seconds if a NOAA warning tone (1050 Hz) is received/detected. If no additional warning tone is received for 60 seconds, the unit will switch back to the last known function mode. The Weather Alert function can be turned “on” or “off” by the Audio/Menu key, as described on page three. When “ON” (default), the Weather Alert icon appears in the display and the weather tuner remains active, even when the radio is turned off (as long as the power is still applied to the radio). If a weather alert is issued, the radio will turn on and play the announcement for 60 seconds, then turn back off and revert to weather alert monitor mode.If the Weather Alert function is set to “OFF”, no Weather Alert icon appears in the display. The radio will not respond to any weather alerts when it is off and will not automatically switch to the weather band if an alert is issued. NOTE: If the unit is programmed for European operation, the WB function will be disabled.

JHD40BT10BLUETOOTH OPERATIONThe JHD40BT includes built-in Bluetooth technology that allows you to connect this head unit to Bluetooth devices for streaming audio playback.About Bluetooth TechnologyBluetooth is a short-range wireless radio connectivity technology developed as a cable replacement for various electronic devices. Bluetooth operates in 2.4 GHz frequency range and transmits voice and data at speeds up to 1 megabit per second. Bluetooth was launched by a special interest group (SIG) comprised of Ericsson Inc., Intel Corp., Nokia Corp., Toshiba and IBM in 1998, and it is currently developed by nearly 2,000 companies worldwide. The Bluetooth word mark and logos are owned by the Bluetooth SIG, Inc. and any use of such marks is under license. Other trademarks and trade names are those of their respective owners.Bluetooth Menu OptionsNOTE: Please note that some BT menu options are only available while the unit is in BT Audio mode.Press and hold the AUDIO/MENU button (3) to enter menu adjustment mode.

JHD40BT12CARE AND MAINTENANCE• Keep the product dry. If it does get wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits. • Keep the product away from dust and dirt, which can cause premature wear of parts.• Handle the product gently and carefully. Dropping it can damage circuit boards and cases, and can cause the product to work improperly.• Wipe the product with a dampened cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the product.• Use and store the product only in normal temperature environments. High temperature can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.IgnitionThe most common source of noise in reception is the ignition system. This is a result of the radio being placed close to the ignition system (engine). This type of noise can be easily detected because it will vary in intensity of pitch with the speed of the engine.Usually, the ignition noise can be suppressed considerably by using a radio suppression type high voltage ignition wire and suppressor resistor in the ignition system. (Most vessels employ this wire and resistor but it may be necessary to check them for correct operation.) Another method of suppression is the use of additional noise suppressors. These can be obtained from most CB/A radio or electronic supply shops.Interference Radio reception in a moving environment is very different from reception in a stationary environment (home). It is very important to understand the difference.AM reception will deteriorate when passing under a bridge or when passing under high voltage lines. Although AM is subject to environmental noise, it has the ability to be received at great distance. This is because broadcasting signals follow the curvature of the earth and are reflected back by the upper atmosphere.TROUBLESHOOTINGSymptom Cause SolutionNo power The vessel’s accessory switch is not onIf the power supply is properly connected to the vessel’s acces-sory terminal, switch the ignition key to “ACC”.Fuse is blown Replace the fuse.No sound Volume is too low Adjust volume to audible level.Wiring is not properly con-nectedCheck wiring connections.The operation keys do not workBuilt-in microcomputer is not operating properly due to noisePress the reset button (19).Cannot tune to radio sta-tion, auto-seek does not workAntenna cable is not connectedInsert the antenna cable firmly.Signals are too weak Select a station manually.
