How to charge LiFe A123 cells using hobby charger?

[Vikas Sontakke]

It claims to support LiFe cells but for the life of me, I can't figure out how to change the charger display from LiPo to LiFe manually. Do I need a real LiFe battery connected before the charger will automatically switch?

This is a Bantam 6 equivalent charger with the usual 4-button interface.

Thanks,
