Frequently Asked Questions
There is 00 on the screen. Is the device broken?
No, the 00 screen is the stand-by screen. Just press and hold the Start/Stop button for 2 seconds to start therapy. When therapy is in progress, a blue arrow
will appear next to the bell on the display screen.
The screen is black, but the green light is on. What does that mean?
The device has a screensaver feature to allow for long battery life. The black screensaver initiates 3 minutes after the last button is pressed. Press any button
to light up the screen. The device will be locked when the screensaver is on.
The green light is on but there is no suction. Is the device broken?
No, the green light is lit when the device is turned on. To start suction, press and hold the START/STOP button for 2 seconds. A blue arrow will appear on the
display screen while therapy is in progress.
I am pressing buttons, but nothing is happening. Are the buttons broken?
No, the device is probably locked. The device self-locks 2 minutes after the last button is pressed to ensure there are not accidental changes to the settings. To
unlock the device, press and hold the START/STOP button and the MODE button at the same time, until the device beeps.
I am pressing the Start/Stop button but nothing is happening.
Check to make sure the device is unlocked. Once the device is unlocked, press and hold the START/STOP button for 2 seconds.
The numbers on the screen are fluctuating. Is that normal?
Yes, the device displays the real-time pressure, and the adjustments necessary to maintain the set pressure. Numbers in a range of ten above and ten below
are normal.
The dressing has a good seal and pressure is mostly around where it should be, but drops to 20 or below, then comes back up. Is
it broken?
No, the device is set to intermittent. Confirm the device is in the intermittent mode by looking at the small box on the screen display. If the box has a dashed
blue line, it is set to intermittent. To switch back to Continuous –Unlock the device, stop therapy by pressing and holding the START/STOP button, then press
and hold the MODE button until you hear a beep. The blue dashed line will switch to a solid blue line. Then restart therapy in the continuous mode.
The black fluctuating numbers won’t come up to the set pressure. Is the device broken?
There is probably a leak in the dressing. To check, clamp the tubing and watch the numbers. If the numbers reach the set range while the tubing is clamped,
the dressing has a leak. If the numbers do not reach the set pressure range while the tubing is clamped, change the canister and recheck. If the issue does not
resolve, contact WHT at (718) 871-2800.
