Installation
Mounting the Bracket
Two options are provided for mounting the bracket (self-tapping screws or machine screws with nuts) to ensure a mounting option ideal for your mounting location. Avoid obstructing airflow to the rear cooling fins on the radio.
NOTE: Mounting holes should be drilled to 7/32”. Before drilling the mounting holes, make sure the area behind the panel where the holes are desired is clear of wires and fuel, vacuum and or brake lines.

Menu Adjustment
Press the AUDIO/MENU button (9) for more than three seconds to enter menu adjustment mode and adjust any of the menu options. When the desired option appears in the display, press VOL+ (7a) or VOL- (7b) to adjust that option. When no adjustments have been made for three seconds, the unit will resume normal operation. The following menu options may be adjusted using this feature:
Beep Confirm (On or Off) - Determines if a beep will be heard each time a button is pressed.
Operation Region (USA or Euro) - Selects the appropriate operating region.
Clock Display (12 or 24) - Selects a 12-hour or 24-hour clock display.
Display Brightness (Low, Mid or High) - Determines brightness level of the display.
Backlight Color (Amber or Green) - Determines the backlight color of the unit.
Turn On Volume (0-40) - Selects desired volume level for the unit to assume when turned on.
WB Alert (On or Off) - Determines if the weather band alert feature is activated.

Tuner Operation
10. Select a Band
Press AM/FM (10) momentarily to directly access tuner mode from any other function mode. When the unit is already in tuner mode, briefly press AM/FM to change between two AM bands (AM1 and AM2) and three FM bands (FM1, FM2 and FM3).
NOTE: If the unit is programmed for European operation, the sequence will be MW1, MW2, FM1, FM2 and FM3.
11. Manual Tuning
Press TUN- (11a) or TUN+ (11b) momentarily to tune the frequency one step higher or lower. Press and hold TUN+ or TUN- for more than one second to tune continuously in the selected direction until the button is released.
12. Seek Tuning
Press SEEK- (12a) or SEEK+ (12b) momentarily to automatically tune the frequency down or up to the next strong station.

13. Preset Stations
Six numbered preset buttons (13) store and recall stations for each AM and FM band. To store a station, select a band (if needed) and then select a station. Hold a preset button for three seconds. The current station will be stored, and the corresponding preset number will appear in the display. To recall a station, select a band and then press a preset button. The unit will automatically tune to the corresponding stored station.
NOTE: Preset buttons recall channels 1-6 on weather band and cannot be set by the user.
Weather Band Operation
14. Accessing the Weather Band
Press WB (14) to directly access the weather band mode from any other function mode.
What is the NOAA Weather Radio?
This 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 costal 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 (CH1), 162.425MHz (CH2),
162.450MHz (CH3), 162.475MHz (CH4), 162.500MHz (CH5), 162.525MHz (CH6) and 162.550MHz (CH7).
How many stations can I expect to receive?
Since the broadcasts are local weather and information, the transmission power is usually very low (much less than AM or FM stations) so you will usually receive only one station unless you are on the edge of two or more broadcast signals. The most you will receive will be two or three, and that is rare.
Is it possible I won't receive any stations?
Depending on location, it’s possible you will 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 TUN+ (11b) or TUN- (11a) to tune to each of the seven channels until you find the weather band station broadcasting in your area.
NOAA Weather Alert
The 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.

Troubleshooting
Problem Cause Corrective Action
No power. Vehicle ignition switch is not on If the power supply is connected to
the vehicle accessory circuits but the engine is not moving, switch the ignition key to “ACC”
The 3A fuse is blown Replace the 3A fuse
No reception Volume turned down too low Adjust volume until sound is heard
Wiring not connected properly Check wiring connections
Radio does not work Antenna cable not connected Insert antenna cable firmly
Volume too high or too low when the radio is turned on
LCD display is dark and difficult to read
No WB function Programmed to “European” Program to “USA” (setup menu)
Weather alert does not function
NOTE: Proper care and cleaning is essential to optimal operation. The JHD905 may be cleaned with mild detergent/water mixture and a soft cloth to remove grease and grime. Do not pressure wash directly on the radio.
Preset volume is set incorrectly Use the Menu adjustment (page 7)
to change preset volume to desired level
Radio too hot Turn radio off and allow to cool
down
Weather alert programmed to “off”
Program to “on” (setup menu)
