Cautions:
• You must use an AC adapter that supplies 9 volts and delivers at
least 300 mA. Its center tip must be set to negative and its plug
must fit the scanner’s
POWER jack. The recommended adapter
meets these specifications. Using an adapter that does not meet
these specifications could damage the scanner or the adapter.
• When you finish using the AC adapter, disconnect it from the AC
outlet first. Then disconnect it from the scanner.
USING VEHICLE BATTERY POWER
You can power the scanner from your vehicle’s battery power using an
optional DC adapter, such as Cat. No. 273-1810.
Cautions:
• You must use a DC adapter that supplies 9 volts (regulated) and
delivers at least 300 mA of DC automotive power. Its center tip
must be set to negative and its plug must fit the scanner’s
POWER
jack. Both of the recommended adapters meet these specifica-
tions. Using an adapter that does not meet these specifications
could damage the scanner or the adapter.
• To protect your vehicle’s electrical system, always plug the adapter
into the scanner before you plug it into your vehicle’s cigarette-
lighter socket. Always unplug the adapter from the vehicle’s ciga-
rette-lighter socket before you unplug it from the scanner.
1. Connect the DC adapter’s 3.4 mm outer diameter/1.3 mm inner
diameter barrel-plug to the adapter’s cable, with the tip set to –.
2. Set the adapter’s voltage switch to 9V.
3. Insert the barrel plug into the scanner’s POWER jack.
