Precautions
1. Use only a Braemar, Inc. certified memory card for
recording. Verify that you are using the correct memory
card. DL900 SD Holters will have “SD” printed on the device
back label.
2. It is very important that you observe the “Early Out”
procedure. Failure to do so may result in the loss of
recorded ECG (Holter) data. See Page 18.
3. Disconnect patient leads before using a defibrillator.
4. Users must ensure that they configure the DL900 with settings
compatible with their ECG analysis software.
5. False positive and false negative pacer detects may occur
when using Pacer Detect.
• False positives – may result from poor electrode
connection to the patient or a large amount of electrical
interference from nearby source.
• False negatives – may occur with pacers that are bipolar
because of a weak pacer pulse signal at the patient’s skin.
6. When viewing the ECG data, the presence of pacemaker
signals in the ECG trace should not be considered true
representations of the actual pacemaker stimulus amplitude.
7. Use of rechargeable batteries is not recommended.
8. Observe local laws for disposal of alkaline batteries.
9. To avoid the possibility of corrosion damage to the monitor, do
not leave batteries in the device when it is not in use.
10. To receive the best recording results, instruct patients to stay
away from heavy electrical equipment or other sources of
electromagnetic interference. Equipment such as electric
blankets and heating pads are included in this group.
11. A minimum of 180s/s and 10 bit resolution is needed for
patients weighing less than 22 lb. (10 kg.).
12. The DL900 7 Day operates at 40 Hz and is not intended for
use with infants.
