Hi Mark,
To re-load engine hours, follow the steps below:
STEP 1 ? ?Accessing Set Mode?: With power off, press and hold buttons 1, 3, 5 and then turn on power. Wait until the displays start reading out values (takes about 15 seconds or less), and then release buttons.
STEP 2 ? ?Selecting decade to change?: Press button 4 once to move to the next higher decade on the digital engine hours display area. There is no visual indication of this, other than when you change the decade value (STEP 3). Pressing the button moves the selection to the left until it gets to the highest decade, after which the next press returns you to the lowest decade.
STEP 3 - ?Changing the decade value?: Press button 5 to increase the decade value as desired. If you go over ?9? it will carry to the next decade. To erase the entire engine hour?s value, select the highest decade and increase it until the display clears. Do this TWICE, and then proceed per steps 1 thru 3.
STEP 4 ? When you are satisfied with what you see, shut off the VM1000.
