Storing Personal Code Number (Battery Removed)

A rechargeable dry cell (Nickel-Cadmium) is employed so that the personal code number can be stored for a certain period of time even when vehicle battery is removed. As a result, this system can store code number in memory for about twenty days.

If vehicle is left without battery for over twenty days, code number will be erased. Enter code number again when battery is remounted on vehicle. The rechargeable dry cell is recharged constantly, thus requiring no replacement.
