Check keypad response after each of the following steps.
A. Make sure the battery has been installed, and the power switch, if any, is
"ON" (Section 7).
B. Use a voltmeter to measure the voltage on the 12 V and G terminals; the
voltage must be between 9.6 and 16 VDC.
C. Disconnect any sensor or peripheral wires connected to the 5 V and 12 V
terminals.
D. Disconnect any communications or storage peripherals from the
