Battery Replacement
The current drain of the ME-9496 is extremely low (typically a few nanoamps when not triggered). Although the coin-cell batteries
inside the Time Pulse Accessory need to be replaced only when operation becomes erratic, regular replacement of the batteries
every three to four years will insure that the Time Pulse Accessory is always ready to function.
To replace the coin-cell batteries, use a small Phillips head screwdriver to remove the two screws from the bottom of the ME-9496
case.
Remember that the Fan Accessory and Variable Speed Motorized Cart rely on their own batteries for power, and not the internal
batteries of the Time Pulse Accessory. Always check the external batteries and their connections before replacing the internal bat-
teries
