USING VEHICLE BATTERY POWER
You can power the HTX-400 from a vehicle’s 12V power source (such as cigarette-lighter socket) using an 9-volt, 900 mA DC-to- DC power adapter and a size I Adaptaplug® (neither supplied) with TIP set to +. Both are available at your local RadioShack store.
Cautions:
You must use a power source that supplies 9V DC
!and delivers at least 900 mA. Its center tip must be set to positive and its plug must fit the HTX-
400's DC 9V jack. Using an adapter that does not meet these specifications could damage the HTX-400 or the adapter.
•Always connect the DC adapter to the HTX-400 before you connect it to the power source. When you finish, disconnect the adapter from the power source before you disconnect it from the HTX-400.
Follow these steps to operate the HTX-400 from a vehicle’s bat- tery power.
1.Insert the Adaptaplug into the HTX-400’s DC 9V jack.
2.Plug the other end of the adapter into the cigarette-lighter socket in the vehicle.
