- The low battery sensor threshhold is controlled by a
- potentiometer. Here's how to readjust the sensor to 4.0
- volts:
-
- 1. Turn the scanner off.
- 2. Connect a digital voltmeter to a well regulated DC
- power supply and adjust the supply to 5.0 volts.
- 3. Connect the power supply to the snap terminals on
- the scanner that would normally connect to the bat-
- tery pack. Be sure to observe proper polarity.
- Connect the positive lead of the supply to the
- female snap, and the negative lead to the male snap.
- 4. Turn the scanner on.
- 5. As you watch the scanner's LCD display, gradually
- reduce the power supply voltage until the scanner's
- low voltage warning begins to flash.
- 6. Read the digital voltmeter. If it reads between 3.9
- and 4.0 volts, no further adjustment is required,
- just disconnect the supply and reconnect the battery
- pack.
- 7. Otherwise, turn off and disconnect the power supply,
- and continue.
- 8. Turn the scanner upside down, and place its
- cloth so as not to scratch the case.
- 9. Remove the bottom tilt foot from the scanner.
- 10. Remove the battery pack.
- 11. Remove the 4 Phillips screws holding the case bot-
- tom, then remove the case bottom.
- 12. Reconnect the power supply to the scanner and set it
- to 4.0 volts.
