Cate Archer was wearing a pager when she was having lunch with Bruno Lawrie at Maximillian's. When she informed Lawrie that she wanted a chance to prove herself, her pager went off summoning her to UNITY Headquarters. When Lawrie informed Archer that this was her chance, she sarcastically replied "probably just a committee member needing a babysitter on short notice."
- When Archer was heading to the West German Alps to investigate Baroness Dumas, she promised to respond to any summons that Mr. Smith would send her. Presumably, this could have been done by pager.
