To replace the batteries
1. Loosen the screws on the back of the SF Unit that hold the battery
compartment cover in place, and remove the cover.
• Lift up the edge of the back cover that was fastened down by the
screws, hinging on the opposite edge.
2. Slide the battery switch to the "Replacement" setting.
3. Remove the battery holder by sliding it in the direction indicated by
the arrow in the illustration.
Caution
Be sure to remove only one battery at a time. Otherwise, you will
lose all data stored in memory.
4. Replace the old battery with a new one, making sure that the positive (+) side of the new battery is facing
up (so you can see it).
5. Replace the battery holder and fasten it in place.
6. Repeat steps 2 through 5 for the other battery.
• Be sure to replace both batteries. Never mix old batteries with new
ones, and be sure to use CR2025 lithium batteries only.
7. Slide the battery switch to the "Operational" setting.
8. Replace the back cover of the SF Unit and fasten it in place using
three screws.
• Be careful that you do not over tighten the screws.

Resetting the SF Unit's Memory
Warning!
The following procedure erases all data stored in the memory of the SF Unit. Perform the following operation
only when you want to delete all data and initialize the settings of the SF Unit.
Remember - you should always keep copies of important data by writing it down, by transferring it to a personal
computer or other SF Unit.
To reset the SF Unit's memory
1. Check to make sure that the power is off.
2. Remove the three screws that hold the back cover in place, and then remove the back cover.
• Lift up the edge of the back cover that was fastened down by the screws, hinging on the opposite edge.

Key Check
Each key has its own key code. The key codes are assigned incrementally from left to right on the keyboard.
(Refer to the keyboard in the schematic diagrams.)
In the auto mode, the key input sequence is limited so that the keys must be pressed in the order of the key
code as mentioned above. If a key is pressed in the wrong order, the SF-6300 beeps.
