Canceling the ongoing rewrite operation:
Click the [QUIT] button.
To rewrite MOT files later, remove and install the battery first.
[Notes for the use of a cable for upgrading]
1. Disconnect the AC charger from the cable. Otherwise charging
starts and the MOT file rewrite operation is interrupted.
2. Make sure the handset battery is sufficiently charged.
If the battery is low, the rewrite operation may fail. Charge the bat-
tery before the operation.
3. If the ongoing rewrite operation is canceled, or interrupted by an
error, remove and reinstall the battery and retry.
[Notes for the use of the Communication Box]
1. When "Press Power Button!" appears, turn on Communication Box
SW from No.10 down to No.1. If the communication BoxSW No.1 is
first turned on, the rewrite on communication BoxSW No. 2 to No. 10
operation will fail.
2. The time to delete the program data varies between handsets. If the
process fails at the default Wait Time (3 seconds), increase the
value.
Consequently, this will increase the time to complete the rewrite
operation.

appears with SUM.
