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.

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.
1. Press and hold the AUDIO/MENU button (12) for more than three seconds to enter menu
adjustment mode.
2. Press the AUDIO/MENU button repeatedly until the “BT PAIR” option is displayed.
3. Press the VOL+ button (10) to begin searching for BT devices.
4. 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.
5. Press the AUDIO/MENU button (12) to choose a device. “PAIRING” appears on the display,
indicating that the pairing process has begun.

6. 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.
7. Upon successful pairing, “SUCCESS” appears on the display. The unit is now paired with
the selected BT headset.
Selecting a Paired Bluetooth Device
1. 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.
2. Press the VOL+ (10) or VOL- button (13) to navigate the list and choose a device.
3. 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
NOTE: Proper care and cleaning is essential to optimal operation. The JHD910BT may be
cleaned with a mild detergent/water mixture and a soft cloth to remove grease and grime.
Do not pressure wash directly on the radio.
