To open a lock after complete battery failure:
Refer to Figure 3.2 and follow the steps below.
1. To provide temporary power to the lock, connect the palmtop
cable, with an external battery pack connected, to the base of the
lock. Although the palmtop PC itself does not need to be connected
to the cable, it will not cause a problem if it is connected.
2. To open the door, use a valid operating token for the lock.
3. Replace the lock’s battery pack. For more instructions, see
Replacing batteries on page 2-36.
4. Disconnect the palmtop cable from the lock.
