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.

TIJNER OPERATION

Select a Band
Press AM/FM (5) to directly access tuner mode from any other function mode. When the unit is already in tuner mode, 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.

Manual Tuning

Seek Tuning
Press SEEK- (16) or SEEK+ (15) to automatically tune the frequency down or up to the next strong station.

Preset Stations
Six numbered preset buttons (17) store and recall stations for each AM and FM band. To store a station, select a band (if needed), then select a station. Press and 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 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 JHD91 0BT 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 JHD91 0BT. Make sure the device is on and ready to receive a signal from the JHD91 0BT.

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 JHD91 0BT.
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 (CHS), 162.525MHz (CH6) and 162.550MHz (CH?).

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.
