ABOUT THE POWER SUPPLY (continued):

The TX50D may also be powered by using a 12-volt vehicle cigarette lighter adapter, available at most electronic supply stores. Make certain that the polarity on the adapter matches what is shown below.

POSITIVE NEGATIVE

Connect the small round end of the adapter to the 12VDC Automobile adapter jack (#26, page 8), then plug the other end of the adapter into the vehicle’s cigarette lighter socket. (In some vehicles, the ignition switch must be in the “on” or “accessory” position to have power at the socket.) NEVER PLUG THE SUPPLIED 15VDC CHARGER INTO THE AMPLIFIER’S 12VDC LIGHTER PLUG!

When using the DC cigarette lighter adapter, the vehicle’s battery will keep the amp charged to its voltage level – if the battery has a 13.5-volt charge, the amp will charge up to 13.5 volts; if the battery is low and only has a 10-volt charge, the amp will discharge down to 10 volts.

CAUTION! The TX50D contains a sealed, rechargeable, lead-acid battery. Improper disposal of battery or replace- ment with any other type may cause leakage, explosion, and/or injury. See page 4 for additional information. Also, refer to product warranty information.
