Meaning

But; however; provided that. Introduces a condition or exception to a previous statement.

A conjunction used to add a restriction, condition, or exception to what was just stated. Very common in rules, instructions, and formal writing: 参加は自由です。ただし、事前登録が必要です (participation is free; however, advance registration is required). More specific than でも or しかし — it narrows or qualifies rather than simply contrasting.

2. 明日は休みだ。ただし、緊急の場合は連絡してください。 Tomorrow is a day off. However, please contact us in case of an emergency.
