5. Using the V key, the next item is the battery voltage. When the battery voltage drops to
3.6 VDC or less, it is time to change the batteries.
If the battery voltage is 3.6 VDC or less when the EPM Programmer is turned on, the
display will indicate LOW BATT VOLTAGE to indicate that the batteries need to be
replaced.
To change the batteries, remove the four screws that secure the EPM Programmer cover
to the main housing. Carefully remove the cover, which will provide access to the
batteries.
6. Using the V key, the last item is the password. The factory default password is 0000. If
the password is set to a value other than 0000, the password function is enabled.
To change the password, press the ENTER key to shift the cursor to the right side of the
display.
Use the V and W keys to scroll to the desired password value. Press the ENTER key to
store the value and shift the cursor back to the left.
Once the password function is activated, the password prompt will appear when the EPM
Programmer is turned on. Use the V and W keys to scroll to the correct password value
and press the ENTER key. If the wrong password is entered, the display will read
INVALID PASSWORD, and the password must be entered again.
