Setting Up the SF Unit

After batteries are loaded, use the following procedures to set up the SF Unit for operation.

To switch power on and off

1. Press ON to switch power on.

• The initial screen for the mode that was seleted when you last switched power off appears on the display.

• lf either of the messages (A or B) shown bellow appears on the display, follow the procedures

described bellow.

Whenever you turn on the power of the SF Unit ,it performs a self-check before beginning operation. If a problem is discovered during the self-check, the SF Unit displays one of the following messages.

Note

• The above messages always appear in English, regardless of the system language setting.

If this is the first time you ever turned on the SF Unit... Perform the RESET OPERATION on page 9.

If this is not the first time you are using the SF Unit... There is probably a problem with the data in memory (data error). Note that once data is lost it cannot be recovered. Such data errors are generally caused by one of the following problems.

• Interruption of battery power.

• Severe electrostatic charge, impact, change in temperature, or change in humidity.

• Hardware problem.

— 5 —

After a data error is discovered, you will not be able to input or edit data. In order to return memory to normal (allowing further input and editing of data), you must perform the RESET operation to clear the memory of all data. Before doing so, you may want to recall important data and write it down (if you don't already have a copy). You can then re-input the data after clearing the memory. The RESET procedure you should use depends on the type of message error message on the display.

"ARE YOU USING A NEW UNIT FOR THE FIRST TIME ?"

1. Make sure that NO is highlighted and then press set. If YES is highlighted, press to move the highlighting to NO and then press SET.

• The message "DATA ERROR ! CHECK YOUR USER'S GUIDE FOR PROCEDURE !" appears on the display at this time.After this message appears, you can press CLEAR to clear it from the display and recall data in order to make a back-up record of it before continuing.

2. Press the RESET button, which is located inside the battery compartment cover on the back of the unit.

• This causes the "CLEAR MEMORY AND SET UP THE UNIT FOR OPERATION ?" message to appear on the display.

3. Press to move the highlighting to YES and then press SET to reset the uint.

• Highlighting NO and pressing SET clears the reset message and displays the Home Time screen.

"CLEAR MEMORY AND SET UP THE UNIT FOR OPERATION ?"

1. Make sure that YES is highlighted. If OFF is highlighted, press to move the highlighting to YES.

• Highlighting OFF and pressing SET turns off the unit without resetting the unit.

2. Press SET to reset the unit.

If you still have trouble after trying the RESET operation, you may have a hardware problem.

• lf a low battery power message appears on the display or if the display remains blank when you

turn power on, replace batteries as soon as possible.

2. press OFF to switch power off.

About Auto Power Off function...

The SF Unit is equipped with an Auto Power Off function that switches power off automatically whenever you do not perform any key operation for about six minutes. To restore power, press ON.

To turn on the EL backlight

There are two ways to turn on the backlight of the display. Pressing LIGHT causes the backlight to turn on for about 15 seconds, and then turn off automatically. Pressing SHIFT and then LIGHT also turns on the backlight, but in this case the backlight stays on as long as you keep performing key operations on the SF Unit . The backlight turns off automatically if you do not perform any key operation for about 15 seconds. Leaving the backlight on for long periods greatly reduces battery life! You can manually turn the backlight off by pressing LIGHT again. Failure of the backlight to turn on indicates low battery power. Replace batteries as soon as possible.
