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.
Attaching the Radio
Once the bracket is securely mounted, use the four included M4 machine screws to fasten the bracket
to the back of the radio. Alternately, the radio can be mounted directly to the instrument panel if access
to the rear of the instrument panel is available.
CAUTION! Do not over tighten the 4 mounting screws. Hand tighten only.

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), 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 (if needed). Press a preset button momentarily, and the unit will 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+ or TUN- 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
Note: Proper care and cleaning is essential to optimal operation. The JHD910 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.
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
Preset volume is set incorrectly Use the Menu adjustment (page
three) to change preset volume to
desired level
LCD display is dark and
difficult to read
Radio too hot Turn radio off and allow to cool
down
No WB function Programmed to “European” Program to “USA” (setup menu)
Weather alert does not
function
Weather alert programmed to
“off”
