The procedure for Voyagers is listed on p. 263 of the manual, "Verifying Proper Operation (Self-Tests)":
For a calculator that does not respond to keystrokes despite having good batteries installed correctly, try these steps in order:
1. Press yx and ON simultaneously, then release.
2. Remove and re-insert batteries.
3. Leave the batteries in the compartment and briefly short-circuit the battery terminals together.
