External battery power supplies contain a final voltage rating in their specifications/documentation (also know as "cut-off voltage" and "end voltage"). The R-26 is compatible with external battery power supplies with final voltage ratings of 9.0 V, 9.5 V, 10.0 V, 10.5 V, 11.0 V, 11.5V and 12.0 V. When connecting an external power supply, set the R-26's final voltage setting the same as the external battery power supply's final voltage rating.
To set the R-26's final voltage setting:
- Press the MENU button and then touch SYSTEM SETUP.
- Touch EXT-POWER.
- Touch the final voltage value that you want to specify.
- Touch BACK to return to the menu screen.
