The Cairo court adjourned the trial to March 5 to provide a translator for the Australian correspondent Peter Greste and to hear prosecution witnesses.
The trial of journalists with the Qatar-based channel comes against the backdrop of strained ties between Cairo and Doha, which backed deposed Islamist president Mohamed Morsi, ousted by the army in July, and his now-banned Muslim Brotherhood.
The journalists are accused of supporting the Brotherhood and broadcasting false reports, after police shut down Al-Jazeera's Cairo offices following Morsi's overthrow.
"I love my family, I'm strong," Greste told reporters from the caged dock with the other seven defendants in court. "The physical conditions (of prison) are good but I'm psychologically drained."

"We know we have done nothing wrong. We have confidence that justice will set us free," he said.
Greste, a former BBC correspondent, and Canadian-Egyptian Mohamed Fadel Fahmy, who was with CNN before joining Al-Jazeera, were arrested in a hotel here in December.
Greste is the only foreign journalist who has been arrested. The other foreigners listed in the indictment are abroad and being tried in absentia.
The government has designated the Brotherhood a terrorist organisation, although the group denies involvement in a spate of bombings since Morsi's overthrow.
Al-Jazeera, which says only nine of the defendants are on its staff, has denied the charges.
The other foreign journalists are Britons Sue Turton and Dominic Kane and Dutch journalist Rena Netjes, who was indicted even though she does not work for the channel.
"Basically (the charges) relate to me aiding and abetting a terrorist organisation by providing money and equipment," she said in a telephone interview.
"I was extremely upset when the boys were put in prison," she said of the jailed journalists. "We were all just thinking the authorities would realise what a huge mistake they made."
The trial has prompted an international campaign by journalists calling for their release. Human Rights Watch said the trial was part of a crackdown on dissent by the interim government.
