BATTERY INSTALLATION
The ADB tester uses four AA and two 9-volt batteries (not included). In order to get the longest use,
rechargeable NiMH batteries are recommended. Alkaline batteries can also be used.
To access the AA battery compartment on the bottom of the unit, remove the two central screws holding
it in place. First, insert the four AA batteries (Image A). Be sure to match up the + and – indications
on the batteries with the + and – indications on the battery compartment. Then replace the battery
compartment lid and the two screws.
To access the 9-volt battery compartment inside the unit, remove the six other screws that hold the case
together. Once removed the case will split into two halves, carefully unplug the ribbon cable (Image
C) and then insert the two 9-volt batteries (Image B). Be sure to match the + and – indications on the
batteries with the + and - indications on the battery compartment. To reassemble the unit, carefully re-
connect the ribbon cable (Image C), and then bring the two halves back together (be careful not to trap
any cables between the screw holes on the two halves). Replace the six screws to secure the unit.
NOTE: Do not use an old battery with a new one, or mix different types of batteries together.

NOTE
Batteries are not included with the ADBT. 4B recommends using rechargeable NiMH batteries.
The ADBT must be powered by batteries to perform direct (heated) testing. However, indirect
(simulated) testing does not require batteries as power will be drawn from the node.
