SETTINGS AND REPORTING FUNCTIONALITY

What settings and therapy statistics can I access on my M Series device?

[Some of the following settings must be enabled by your homecare provider. Please refer to the user manual for instructions on how to access or change these settings.]

Patients have access to the following settings and therapy usage data:

C-Flex (on REMstar models) —If enabled by your homecare provider, patients can change the C-Flex setting (1, 2, 3)

Bi-Flex (on BiPAP models) —If enabled by your homecare provider, patients can change the Bi-Flex setting (1, 2, 3)

Altitude Adjustment —The REMstar and REMstar Plus models require manual altitude adjustment (1=<2500 feet, 2=2501-5000 feet, 3=5001-7500 feet). The REMstar Pro, REMstar Auto, BiPAP Plus and BiPAP Auto models have automatic altitude adjustment.

Ramp Start Pressure —If Ramp is enabled by your homecare provider, patients can adjust the starting ramp pressure. Patients cannot change the ramp time.

Mask Alert —Patients may activate and deactivate the Mask Leak Alert which will sound a brief alarm if the device detects excessive system leak.

Auto Off —Patients may activate and deactivate the blower automatic turn off mechanism which will shut the unit down after a period of patient disconnect.

Usage Statistics —Patients may view their usage data on the display located under the flip lid. Display usage data includes 7 and 30 day average hours of device usage and number of sessions >4 hours. Our REMstar Pro and Auto, as well as BiPAP Plus and Auto models will also display apnea/hypopnea index and System leak.

What are the reminders that appear on my display screen every few months?
Your homecare provider may have set up your device to display reminders related to your therapy management such as replacing your filters, mask or tubing. These reminders may appear at the end of a therapy session. The reminder will flash for a period of 6 minutes every time the blower is turned off until you acknowledge the message by pressing any of the four navigational buttons (<, >, -, +). After 72 hours from the start of the reminder period, the patient reminder timer will automatically shut off and reset. There is no audible alarm. Regular replacement of your therapy accessories is an important part of maintaining a comfortable and successful sleep regimen.
POWER SUPPLY AND ELECTRICAL
Are there fuses for the patient to replace? There are no user-replaceable fuses.
When traveling abroad, do I need a converter? A converter is not needed, but an international plug adapter may be required to make the power cord compatible with the power outlets of that country.
When traveling to a destination without electrical outlets, how can I power my device? Your device can be powered by a portable battery. A battery pack and carry case is available for purchase through your homecare provider.
HUMIDIFICATION AND HUMIDIFIERS
How many hours of humidification will I receive with a full chamber of water? The humidifier tank, which is 325 ml. (1 2/3 cups), will provide humidification for at least 8 hours per night. This has been validated under the most extreme conditions of pressure setting, humidification setting and sleep environment.
Note: Excess mask or other system leak will increase water consumption.
Can I use the humidifier for cool pass-over humidification?
Yes. Set the humidification dial to zero and the heat source of the humidifier is turned off.
Is there preheat? No. The blower must be on to activate the humidifier. The humidifier knob has 6 settings, ranging from 0 to 5, with 0 indicating OFF. The ideal humidity setting depends on room temperature and humidity. Initially a setting of 2 is recommended.
Will the humidifier run if there is no water in the tank? If the humidifier is set from 1 to 5 and the blower is on, the humidifier will continue to control heat to the set level even if there is no water in the water tank. This situation will not cause damage to either the humidifier or the humidifier tank.
Will the humidifier run if the water tank is not in the humidifier? The humidifier will run if the water tank is not in the humidifier but no therapy will be delivered to the patient. The air rush noise also will also increase substantially. No damage will result to the humidifier.
Can I remove the water tank when the humidifier is on? Yes. However there is a potential for the water in the tank to be hot (a potential low grade burn may or may not occur). We recommend turning the dial to 0 and letting the unit cool for 15 minutes before removing the water tank.

How do you clean the outlet port of the humidifier?

Use a damp bottle brush or a damp cloth. To clean, insert the brush or cloth approximately 3 inches into the outlet opening.
Is the water tank dishwasher safe? Note that the material of the water tank is dishwasher safe. However, the middle seal "O" ring must be removed before cleaning. After cleaning, the "O" ring must be replaced before being used. We recommend a manual soap and water bath instead of using your dishwasher.
Can I replace my water tank? Yes. Contact your homecare provider to order a new water tank.

The M Series system includes the following items: M Series device, 6 ft flexible tubing, carrying case with padded shoulder strap, power supply, AC Power cord (3ft), reusable gray foam filter (Qty 2), disposable ultra-fine filter, patient User Manual, integrated heated humidifier (if ordered), integrated SmartCard module (if ordered)
What is the difference between the gray foam and white particle filter?
The device uses a gray foam filter that is washable and reusable, and an optional white ultra-fine filter that is disposable. The reusable filter screens out normal household dust and pollens, while the optional ultra-fine filter provides more complete filtration of very fine particles. The gray reusable filter must be in place at all times when the device is operating. The ultra-fine filter is recommended for people who are sensitive to tobacco smoke or other small particles. Two reusable gray foam filters and one disposable ultra-fine filter are supplied with the device.
