I do not know that particular system, but any normal construction has either mains-frequency transformer based or "primary switcher" type mains-to-internal-DC power supply.
Assuming an old-fashioned mains frequency transformer: In most cases you can use an transformer to convert 220-230V down to 110-120V range with an 2:1 transformer and assume that 50 Hz is OK for a device designed for 60 Hz. A transformer designed for 60Hz will work slightly warmer when given 50Hz due to heavier magnetization, but I believe all sensibly dimensioned constructions can take that. In all cases when I have personally adapted an American device to European voltage, I have not observed any serious overheating.
In case of primary switcher, the frequency should mean even less. However, the power factor figures can be anything from near-one (for new and good constructions) to ugly (old directly rectifying non-power-factor-corrected ones). The latter may demand a biggish transformer for good function.
But one warning: Do NOT use those small, lightweight, "travellers transformers" for the purpose. Get rather a big, heavy, and preferably bit overdimensioned real iron-and-copper transformer. (Remember, transformer size is function of VoltAmps, not Watts, and power factor can make VA figure much higher than wattage for those built in AC/DC power supplies!)
Also, for electrical safety, it is better to use an isolating type transformer (not non-isolated one), even if they usually cost more, and are somewhat bulkier.
Good luck,
