More than 75,000 memory cards have been recalled from automated vote counting machines in the Philippines - a week before presidential elections there.
Some of the machines have been found to misread ballots.
Computerised vote-counting will be used for the first time in the Philippines in the elections on 10 May.
Critics have been warning of possible glitches in the machines for some time.
The BBC reports there are increasing calls for a manual vote count in parallel with the automated system.
The election is for a new president, vice-president, Congress, half the Senate and all provincial officials.
