2 Option E is mandatory for all -9 models. Models with -5E or -6E are functional down to –40 °C.
3 Feature R excludes option P and vice versa. Option P is not available for battery charger models.
4 Option D excludes option V and vice versa; option V is available for models with 5.1 V output only (LK4003, etc.).
5 Option K is available for models with 5.1 V output only (LK4003, etc.) to ensure compatibility with LK1001 models.
