Service and Maintenance
• Do not open the Digitest 3 Power Unit, except to change the bat-
tery. There are no user-serviceable parts inside. Internal repairs
are to be made only by authorized Parkell personnel, by returning
the unit to the service address at the end of these instructions.
• Avoid dropping the Power Unit or subjecting it to physical shock.
• Battery should be removed if unit is to be stored unused for more
than 30 days.
• To prolong battery life, the device automatically turns off after
14 seconds of inactivity.
• When the battery is low, the letters "LO" will blink on the screen
when the device is initially turned on. If the battery is low, replace
it as explained in the section "Installing/Replacing the Battery".
• If a Tooth Probe becomes loose in the mount of the Power Unit,
it may be tightened by carefully inserting a flat screwdriver blade
into the split metal base of the probe and gently expanding the
sides apart with a twist of the tool (Figure 1).

• Discard and replace any Tooth Probe if the metal or the insulation
becomes damaged during use.
Installing / Replacing the Battery
• The Digitest 3 Pulp Vitality Tester comes with a high-output,
9-Volt alkaline battery.
• To install the battery, remove screw (Figure 2) and carefully lift off
the plastic battery door by gently pulling it away from the Power
Unit (Figure 3). Withdraw the old battery from the battery enclo-
sure, and unsnap it from the wire battery connector (Figure 4).
Discard in accordance with applicable laws.
• The fresh battery should be snapped onto the connector and
placed in the Power Unit so the top end attached to the connector
is placed into the opening first (Figure 5). Slight pressure on the
bottom of the battery will help it to slide home (Figure 6). Replace
the plastic battery door by engaging the tabs on the bottom first
(Figure 7), and tighten the screw gently (Figure 8).
• The replacement battery may be a Duracell® MN1604, Pana-
sonic® 6AM6 or equivalent. Although rechargeable 9-Volt bat-
teries may be utilized, they will require more frequent charging
because of the considerable voltage required to perform the
pulp testing procedure.
Digitest 3 Setup Prior to Performing Pulp
Vitality Testing
• To accurately diagnose the condition of the tooth, pulp test-
ing must be performed on a patient who has not received local
anaesthesia or gas analgesia. Make sure to use the Digitest 3
BEFORE you perform these procedures.
• Fully explain to the patient what you will be doing prior to the pulp
test, so they are not surprised during the test. Using the words
