the Cpap.com website requires you to take a picture of the doctor’s prescription and upload it to the website. Cpap.com will set the settings based on the settings stated in the prescription. In any case , when the Resmed 10 arrives in Singapore, you can bring it to the sleep clinic and ask the technician to check the settings or to make changes to the settings (eg set to Singapore time).
The only thing to maintain that I know of is to change the filter, which should not be difficult to do . CPAP.com sells the filter refills.
will need a multi plug as the CPAP.com machine comes with a US 2-pin plug . No need to convert voltage as Resmed 10 runs on worldwide voltages.
