i just started at a busy inner city agency that uses the MRL (pic 40 i believe). it's biphasic, but i've been told conflicting info about energy settings. i was told once that you use the monophasic setting and the machine converts it to the proper energy, but i've also been told to use the standard 200 for biphasic. i've been searching for info on the net about it, maybe a user manual or something like that with no luck. if anyone knows anything about this monitor or where i could find this info, i'd appreciate it.
