If your instrument is fitted with a digital pressure gauge, this tutorial will demonstrate how to replace the two (2) AA batteries that supply power to the gauge. This tutorial applies to the following Instruments:
Model 600D, Model 615D, Model 1505D, Model 1515D, Model 1505D-EXP, and Model 600D-EXP.
You will need: 1 Flat Head Screwdriver, 1 Small Flat Head screwdriver, 2 AA Batteries.
…
Step 2: Remove the Instrument Panel and turn it over to expose the back side of the instrument panel.
Step 3: Grasp the back of the gauge and turn Counter-Clockwise to the “un-locked” position. If the back has not been removed for awhile, it may be difficult to break the seal of the o-ring.
If you have any questions or issues replacing the batteries, please give us a call or email and we will be happy to assist you.
