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 to be
drilled is clear of wires and fuel, vacuum and 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.
WIRING
The wiring diagram depicts the wiring connections required for proper operation of the unit.

recall a station, select a band (if needed). Press a preset button to tune to
the corresponding stored station.
NOTE: Preset buttons recall channels 1-6 on weather band and cannot be
set by the user.
BLUETOOTH OPERATION
The JHD910BT includes built-in Bluetooth technology that allows you to connect this head unit to wireless headphones and certain other Bluetooth devices.
About Bluetooth Technology
Bluetooth 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.
Pairing a Bluetooth Device
Before you begin, consult the owner’s manual for the Bluetooth device you want
to pair with the JHD910BT. Make sure the device is on and ready to receive a
signal from the JHD910BT.
-
Press and hold the AUDIO/MENU button (12) for more than three seconds to enter menu adjustment mode.
-
Press the AUDIO/MENU button repeatedly until the “BT PAIR” option is displayed.
-
Press the VOL+ button (10) to begin searching for BT devices.
-
The unit will display a list of devices found. If more than one device is found, an arrow appears, indicating more choices. Press VOL+ or VOL- to navigate to the correct device.
-
Press the AUDIO/MENU button (12) to choose a device. “PAIRING” appears on the display, indicating that the pairing process has begun.
-
Once a connection is made with the device, “COD: ****” appears on the display. Enter “0000” and then press the AUDIO/MENU button to complete the pairing process.
-
Upon successful pairing, “SUCCESS” appears on the display. The unit is now paired withthe selected BT headset.
Selecting a Paired Bluetooth Device
-
To access a list of paired Bluetooth devices, choose “BT LIST” from the system menu (see “Menu Adjustment” on page 6) to view various devices connected to the JHD910BT.
-
Press the VOL+ (10) or VOL- button (13) to navigate the list and choose a device.
-
Press and hold the AUDIO/MENU button (12) to select the chosen device. The radio will display “LINKING” and then the audio output will switch to the selected Bluetooth device.
NOTE: When connected to Bluetooth headphones, the JHD910BT speaker output is automatically muted.
WEATHER BAND OPERATION
Accessing the Weather Band
Press the WB button (7) to directly access the weather band mode from any
other function 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 (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 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 TUN+ (11) or TUN- (9)
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
Table 1: Troubleshooting
| Problem | Cause | Corrective Action |
