ENGLISH ■ BATTERY INSTALLATION/REPLACEMENT • Install the batteries as shown below. • When the ERROR/BATT. indicator lights three times after operating a key, the batteries are weak. Replace the batteries at this time. • All of the memorized functions will be retained while you replace the batteries. However, if no batteries are installed for a few hours, the memory will be erased and will have to be programmed again. • Be sure to follow the diagram at the bottom of the compartment to insure proper positive (+) and negative ( -) polarity. • Do not use old and new batteries together. • When the unit is not to be used for a long period of time, remove the batteries from the battery compartment. Should battery fluid leaks, wipe away the fluid in the battery compartment thoroughly before inserting new batteries. 3
