Cautions:

You must use a Class 2

!power source that sup-

plies 12V DC and deliv- ers at least 500 mA. Its center tip must be set to positive and its plug must fit the scanner's DC 12V jack. The supplied adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter.

Always connect the AC adapter to the scanner before you connect it to AC power. When you finish, dis- connect the adapter from AC power before you disconnect it from the scanner.

Warning: Do not use the AC adapt- er’s polarized plug with an extension cord receptacle unless the blades can be fully inserted to prevent blade ex- posure.

Using Your Vehicle’s Battery Power

If your AC power fails (during an emergency, for example), you can power your scanner from your vehi- cle’s cigarette lighter socket with an optional DC cigarette lighter power ca- ble, (not supplied).

To connect an optional DC cigarette lighter power cable, insert its barrel plug into the DC 12V jack on the back of the scanner, then plug the power cable into your vehicle’s cigarette lighter socket.

Cautions:

You must use a power

!source that supplies 12V DC and delivers at least

500 mA. Its center tip must be set to positive and its plug must fit the scanner's DC 12V jack. The sup- plied adapter meets these specifi- cations. Using an adapter that does not meet these specifica- tions could damage the scanner or the adapter.

Always connect the adapter to the scanner before you connect it to the power source. When you fin- ish, disconnect the DC adapter from the power source before you disconnect it from the scanner.

Note: If you use a cigarette lighter power cable and your vehicle’s engine is running, you might hear electrical noise from the engine while scanning. This is normal.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an amplified extension speaker (available at your local Ra- dioShack store) positioned in the right place, might provide more comfortable listening.
