Battery Removal and Replacement

Model 986 Thermometer

1. Remove the Probe Cover box holder on the back of the

instrument by pressing with your index finger on the latch

located on the rear of the Probe Cover box holder.

2. Remove the batteries.

3. Press the Mode button for approximately five seconds to

discharge the electronics.

4. Install two new AAA, alkaline batteries according to the

battery polarities marked inside the battery compartment.

Verify that the thermometer completes a power on reset

test (page 7), and then goes blank.

CAUTION: Incorrect battery polarity may result in damage

to the thermometer.

5. Snap the probe cover storage assembly in place by inserting the

bottom tabs first and then snapping the latch on top.

Under normal use, battery life will provide approximately 3,000

normal temperature measurements, based on an average 22.2°C

(72.0°F) ambient temperature. Colder ambient temperatures,

excessive peak monitor measurements, and other usage patterns

can reduce battery life.

Instruments are shipped with fresh batteries, but we cannot

guarantee full life from the first set of batteries due to potential long

storage times between shipping and actual use. Battery life can

also be reduced by storage at elevated temperatures.

If you are experiencing short battery life, refer to Battery Life

Problems in the Troubleshooting table on page 22.
