Dear JENSEN Customer  
Selecting fine audio-visual equipment such as this TV unit you've just purchased is only the  
start of your enjoyment. Now it's time to consider how you can maximize the fun and  
excitement your equipment offers. This manufacturer and the Electronic Industries  
Association's Consumer Electronics Group want you to get the most out of your equipment  
by playing it at a safe level. One that lets the sound come through loud and clear without  
annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.  
Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of  
sound. So what sounds "normal" can actually be loud and harmful to your hearing. Guard  
against this by setting your equipment at a safe level BEFORE your hearing adapts.  
To establish a safe level:  
Start your volume control at a low setting.  
Slowly increase the sound until you can hear it comfortably, clearly without distortion.  
JDTV-750 User Manual, page 3  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Once you have established a comfortable sound level:  
Set the volume control and leave it there.  
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After  
all, we want you listening for a lifetime.  
We Want You Listening For a Lifetime  
Used wisely, your new TV equipment will provide a lifetime of fun  
and enjoyment. Since hearing damage from loud noise is often  
undetectable until it is too late, this manufacturer and the  
Electronic Industries Association's Consumer Electronics Group  
recommend you avoid prolonged exposure to excessive noise.  
Customer's Record:  
The serial number of this product is found on its bottom. You should note the serial number  
of this unit in the space provided as a permanent record of your purchase to aid in  
identification in the event of theft of loss.

Notes  
While recharging, you may watch the TV as usual but charging time will be extended.  
Do not overcharge the player after the initial charge. Overcharging could shorten the  
battery’s life and charging capacity.  
The Li-ion battery pack will normally offer up to 500 charge/discharge cycles.  
The Li-ion battery will discharge slowly on its own even when the unit is not in use, so if  
the unit is not used for an extended period of time it will be necessary to recharge the  
unit at least once every 6 months to maintain normal performance.  
Battery Warnings  
1. The battery could cause injury or explode if incorrectly replaced. Replacement should be  
by a qualified technician and only with the same or equivalent type of battery.  
2. Do not disassemble, crush, short-circuit or incinerate your battery as it may cause fire,  
injury, burns, explosion or other hazards.  
3. Please dispose of properly for recycling.  
Replacing the Rechargeable Battery Pack  
After regular use over a period of time, the internal battery pack may store less and less  
energy per recharge than when it was fresh or even fails to recharge. If that happens,  
follows the procedure below to replace it:  
1. Set the On/Off Switch of the TV to “OFF”.  
2. Open the Battery Compartment Cover and  
carefully unplug the old battery pack from the  
TV unit. Gently insert the plug from the new  
battery pack as shown. Note that the plug is  
polarized and will only fit into the connector one  
way. The plug should never be forced into the  
connector.  
3. Replace the battery compartment cover  
securely.

you are moving along with your TV set;  
you are operating the TV set inside a moving vehicle;  
there are external interferences due to other RF devices nearby.
