Q200/HE Recorder

Do I have to use QRS Diagnostic flash/memory cards in the Q200/HE recorder?
Flashcards from other vendors may be used in the recorders, however, because some card manufacturers provide memory cards which draw too much battery current, some cards may cause the batteries to be depleted prematurely resulting in the Holter stopping early. Because of this, we recommend that you first test cards purchased from another vendor for a greater amount of time than the expected use. Also, before using a new flashcard, you will need to format the card using the INITIALIZE function in the Holter program.


Can I use SDHC flashcards instead of SD cards in my Q200/HE recorder?
No. These are not supported in the Q200/HE recorder.


When should I replace a cable?
A problem with your recordings may be the result of a cable that is not functioning properly because it is damaged or old. First check to see if your cable is damaged or badly worn, if so, it should be replaced. Even if the cable appears to be fine, a cable that needs replacing may result in one or more of the following issues:

  • Poor quality hook-ups – any or all channels are artifact
  • Low voltage QRS
  • Lead quality test always below 3


How do I care for the cable?
By properly caring for your cables you can keep them in a good working condition for an extended period of time.

  • Don’t bend or wrap wires around recorder
  • Clean leads between uses with metricide or bleach
  • Keep electrodes at the right temperature.
  • Ensure electrodes are new – not dried out or rusted.
  • Check cable for breakage between uses.

Function Issues

Why is my recorder continually counting and won’t begin recording?
Remove and erase the card using the Holter program and reinsert. If this does not solve the problem, please call your distributor or QRS Customer Care for further troubleshooting or an RMA#.


Why is my recorder stopping before it should?
The shortened recording times may occur because the Holter is shutting down due to a depleted battery.  One cause of premature battery depletion is flash/memory cards that draw too much current. The memory card provided by QRS has been tested to meet the specification of the Holter unit, drawing a low current to maximize battery life. There are a number of memory card manufacturers and vendors who provide memory cards with much greater current draw. Flash/memory cards vary greatly with respect to the current that they use, even when purchased from the same manufacturer. They still meet the specification for the card, but achieve it at the expense of very high current. This high current will deplete the battery in less than the desired recording time.  Lexxar and SanDisk are two manufacturers that have been tested and are recommended for use with the Q200/HE. If you choose to purchase cards from other manufacturers, test the card for a greater amount of time in the Q200/HE recorder than the expected use to determine its effect on battery life.

 

Why am I getting a “Memory Full” error message and a short recording?
The patient’s Holter data is stored in the recorder on a removable SD card. To store 24 hours in normal mode, 28 megabytes (MB) is required. To store 24 hours in high mode, 56 MB are required, and a 14-day recording in high resolution mode would require about 760 MB. To view the actual size of the flash.dat file on your card, put the card in the reader and view the file when you are prompted to do so. If you have enough capacity on your SD card, but are getting short recordings, the flash.dat file on your SD card may have been corrupted. You can fix this problem by reformatting and re-initializing your card. The instructions for doing this can be found in the Holter LX Analysis International User Guide starting on page 4. If you sometimes do recordings that are more than 48 hours, be sure to choose the option that does not specify "less than 48 hour recording." Also, be sure to allow the process to complete before removing the SD Card from the reader.


How do I remove the flash/memory card from the Q200/HE recorder?
Gently press inward on the SD card to release. The card will pop-out. Never pull the card out – it may damage the recorder.

 

Which software should I use with my Q200/HE?
To use the Q200/HE in Holter mode, you must have some level of Holter LX Analysis software. The levels are Enhanced, Enhanced Plus and Pro. Each level offers different capabilities; download the Holter LX Analysis Features Matrix learn more about each level of software. To use the Q200/HE in telephonic Event mode (this is the most common method of transmitting event recordings), you can use ANY event software. However, using our LX Event software makes life a bit easier and guarantees that the telephonically transmitted data with patient header information will be correctly/automatically received by the receiver. To use the Q200/HE in data card Event mode (this special mode is available only to users of our hardware and software), you must use our LX Event software.


How do I edit the Patient ID if I make a mistake while entering it into the Q200/HE recorder?
When entering the characters for the Patient ID, press the ENTER button to advance from one character to the next. If you need to backspace, hold down the ENTER key for a bit longer than normal. When you have entered the complete Patient ID, finish by pressing the EVENT button. Once you have entered the Patient ID and completed the process by pressing and holding the EVENT button, the only way to change the Patient ID is to remove the battery and start over again. See, "To Start the Recorder for Holter", on the Q200/HE Hook-Up Guides.

 

My Q200/HE recorder is displaying a “Lead Loose” message – what does this mean?
Electrodes that are dried out will cause this message to appear and should be replaced. However, some types of electrodes, including the new, high-impedance gel formulations, cause the “Lead Loose” message to be displayed even though there is not an issue with the signal quality. If you are receiving an adequate signal, you can turn the “Lead Loose” message off under “Settings.”
 

How do I switch the Q200/HE recorder from Event monitoring to Holter recording?
After deleting the events by pressing either arrow for 3 seconds, reboot the recorder by removing and reinserting the battery. Then, interrupt the 15-second countdown by pressing ENTER, down arrow, up arrow and the EVENT button. Now press ENTER and go to the General Settings menu where you can change the recording type from Event to Holter. The Q200/HE Hook-Up Guides in your hardware kits also tell you how to start your recorder for Holter or Event.

Software

What should I do when I get the message, “Flash file not found” on my computer?
First, make sure that the card reader is plugged in and that a card is inserted correctly into the reader. Second, it may be that your computer can no longer see your Card Reader. To fix this, remove card reader plug from the computer and plug into a different USB port on the computer. Third, try turning off and restarting your computer. If you still cannot see the Flash file, your reader may need repair. Try using another reader if available, or call your distributor or QRS Customer Care for further assistance.


What do I do when I see the message, “Card has files other than flash.dat, use Explorer to erase?”
This means that there are files on the card other than flash.dat. You must remove these files using Windows by clicking on “Start” and then “My Computer”. Double-click on the appropriate Removable Disk to see all of the files on the card. Delete all files except for flash.dat.


How do I install the Holter LX Analysis software?
Installation instructions were included in your software kit and also can be found in the Holter LX Analysis Software Manuals. If you encounter problems in the Installation process, contact your distributor or QRS Customer Care.


How can I customize the Holter LX Analysis software?
Refer to the Holter LX Analysis manuals for instructions on how to customize the software using the CONFIGURATIONS feature.


How often should I back up my Holter data?
Back-ups should be done on a regular basis as determined by your organization. In order to do backups, your computer must have a CD drive. Instructions on how to back up your software is included in the manual.

 

What should I do when the software identifies pauses that are not real?
If the QRS complexes are very small, some of them can be missed so that the software identifies false positive pauses. If that happens, go to REVIEW > CALIBRATION, move the calibration lines as close to the baseline as possible, and press DONE. The software will reanalyze the signal using a higher gain and find the small QRS complexes.


How do I change Holter LX Analysis to an alternate language?
In order to set up an alternate language in Holter LX Analysis, you will need to do the following:

  • Install software on your desktop
  • Open the Utilities screen and change the language to what you desire.
  • Open Holter LX Analysis and go to File > Preferences > Configurations.
  • Save one more new configuration by copying the "Standard" and saving the new configuration with a name of your choice.
