AlcoSensor Operation / Problems
Alco-Sensor III (version without the red mouthpiece ejector button)
Problem: Display reads "888."
Solution: "888" is the message that the battery is low. Replace the battery with a fresh 9 volt alkaline battery.
Note that the current version Alco-Sensor III (with red mouthpiece ejector button) displays the message "bat" for low battery.
Problem: Display keeps cycling back to temperature display (i.e., "25 ºc") without going to the message "TEST."
Solution: Battery may be low. Replace battery with a fresh 9 volt alkaline battery.
Problem: Alco-Sensor FST will not turn on when pressing ON button.
Solution: Battery may be low, or battery contacts may be corroded. Replace all batteries with fresh alkaline AA batteries, and clean battery terminals if there are signs of corrosion.
RBT IV Printer
Problem: RBT IV printer will not print.
Solution: Printer battery may need charging or replacing.
