3.4.5 E2 Initialization
EEPROM Initialization:
Note:
The EEPROM device must have been previously initialized for the remote to be able to
get into the Factory RF Channel Test Mode.
Press <Re-Sync> key first then press <CH-> key, hold down both keys for about 3 seconds, then
released. The software will enter the E2 Initialization mode WHEN the <Enter> key is pressed
and released after the above described sequence.
<<Re-Sync> + <CH->>
1. If
<Enter>
key is pressed/released after the above sequence, the software will initialize
the EEPROM. (In the software test module, this process completes with 4 LED blinks
indication)
2. If <AnyKey> key, other than <Enter> key, is pressed after the above sequence, the
software will abort the EEPROM Initialization mode. (In the software test module, this
error condition will be indicated by a long LED blink).
Within 10 seconds (timeout value) after the above sequence entry, if NO key is pressed, the
software will exit the EEPROM Initialization mode and the EEPROM device will not be initialized.
The software will then return to its normal operation. But during this 10 seconds time, if the
Pointer device is activated, the software will exit the EEPROM Initialization mode and will service
the pointer movement of the remote.
