3. User ID settings
3.1 Description
The user ID is stored into the internal serial EEPROM and the stored data is kept even though the
system power down.
3.2 User ID setting procedure:
1) Insert batteries into the keyboard.
2) Push the `Wakeup/ID set’ button on the RF Base station and hold down for three seconds.
Power/Data indication LED will blink in every a second.
3) Type ESC key with Left-Control, Left-Shift and Right-Shift key down combination.
The Power/Data indication LED will blink still.
4) Input user ID number that is 1 to 255 with the numeric keys on the keyboard and than type Enter key.
After input the Enter key, the Power/Data indication LED will stop to blink.
5) Once the user ID setting is done, the RF Base station automatically returns back its normal operation
mode.
∗ Note: Step 2 though step 4 must be done within 30 second. Otherwise, the RF base station will cancel
the matrix ID setting procedure. In the case, the operator will have to retry from step 2. If a wrong key
has typed, the keyboard will cancel the user ID setting procedure. In the case, if the Power/Data
indication LED on the RF base station is still blinking, the operator will have to retry from step 3.
Otherwise, the operator will have to retry from step 2.
