Instruction manual for the A&D UA-1040TBLE Voice Guided Premium Upper Arm Blood Pressure Monitor with Bluetooth and TriCheck averaging.
Instruction manual for the A&D UA-1040TBLE Voice Guided Premium Upper Arm Blood Pressure Monitor — a Bluetooth-enabled oscillometric monitor with voice announcements, TriCheck triple-measurement averaging, and A&D Heart Track app connectivity.
Monitor: Air Socket / Air Connector Plug, DC Jack, AC adapter plug, Button, SET Button, Volume Button, START/STOP Button, Display, Battery Compartment with Battery Cover (uses 4x 1.5V AA/R6P/LR6 batteries).
Display icons: Memory, Average, Pressure Settings, Bluetooth® Connection, I.H.B. (Irregular Heartbeat) Symbol, Movement Error Symbol, Cuff Fit Error Symbol, Heart Mark, Pressure Rating Indicator / Cuff Inflation Meter, TriCheck™ Symbol, Battery Indicator, Clock Display, AM/PM Mark, Systolic/Diastolic Pressure, Pulse Rate.
| Symbol | Meaning | Recommended Action |
|---|---|---|
| I.H.B. | Irregular heartbeat detected during measurement | Reading still provided; consult physician if this appears frequently |
| TriCheck mode icon | Three consecutive measurements being taken/averaged | — |
| Movement error | Body/arm movement detected | Take another measurement, remain still |
| Cuff fit error | Cuff applied too loosely | Apply cuff correctly, remeasure |
| Low battery (blinking) | Batteries need replacement | Replace all batteries with new ones |
| ERR VF | Pressure didn't increase during inflation / cuff applied incorrectly | Apply cuff correctly, remeasure |
| PUL DISPLAY ERROR | Pulse not detected correctly | Remove/reinsert batteries, press START/STOP again |
| ERR E / ERR 9 | Internal error | Remove batteries, press START/STOP, reinsert batteries; contact dealer if persists |
| Err 10 | Communication (Bluetooth) failed | Retry communication; contact dealer if persists |
| Pr | Pairing in progress | — |
Caution: Don't mix old and new batteries. Wait at least 2 seconds after the device turns off before replacing. Remove batteries entirely if not using the device for an extended period.
Insert the AC adapter plug into a 120V outlet, then connect it to the DC jack on the monitor. Insert the air connector plug firmly into the air socket.
Press the SET button, then use the arrow buttons to set year, month, day, and hour, pressing SET after each. The next setting is pressure.
Default is AUTO (automatic pressurization). For faster readings, set a fixed value about 30 mmHg or more above your expected systolic pressure using the arrow buttons, then press SET to move to TriCheck mode setting.
Press the Volume button to cycle: Volume setting → Language setting → Instruction (voice) setting → standby.
Automatically takes three consecutive readings, one minute apart, and averages them per American Heart Association recommended methodology. Default is OFF; enable during the clock/pressure setup sequence.
| Catalog # | Cuff Size | Arm Size |
|---|---|---|
| UA-289A | Small | 6.3–9.4" (16–24cm) |
| UA-290A | Medium | 9.0–14.6" (23–37cm) |
| UA-291A | Large | 12.2–17.7" (31–45cm) |
| UA-420A | Wide Range | 8.6–16.5" (22–42cm) |
Check the index/proper-fit-range markings on the cuff itself; if the index falls outside the range, contact your dealer for a replacement (the cuff is a consumable). Wrap the cuff directly against bare skin, 1–2cm above the inside of the elbow, with the artery position mark aligned; avoid tight clothing under the cuff.
Press START/STOP to begin — takes 3 measurements 1 minute apart, showing a running average after the 2nd and 3rd readings, then stores the average of all three. Canceling before completion (via START/STOP) discards the data.
If re-inflation happens repeatedly, set a fixed pressure (180, 210, or 240 mmHg — about 30mmHg above your expected systolic) during setup instead of AUTO, to skip re-inflation cycles.
If re-inflation still occurs even at 240 mmHg fixed: press and hold START/STOP while the zero blinks until a number ~30–40 mmHg above your expected systolic appears, then release to begin measurement at that pressure.
If the mobile device can't receive data at measurement time, up to 90 sets are stored temporarily and transmitted on the next successful connection (oldest data is deleted beyond 90 sets). The monitor's clock auto-syncs to the mobile device's time during pairing.
Stores the last 90 measurements, announced by voice as displayed. Press the arrow buttons to cycle through: average of all data → average of AM measurements (4:00am–9:59am) → average of PM measurements (6:00pm–1:59am) → most recent reading → oldest reading.
Delete all memory: press both arrow buttons simultaneously until the icon blinks, confirming deletion.
The monitor still provides a reading with an irregular heartbeat, flagging it with the I.H.B. symbol. The Cuff Inflation Meter on the left of the display moves up during inflation and down during deflation/measurement.
| Classification | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | < 120 | and < 80 |
| Elevated | 120–129 | and < 80 |
| Hypertension Stage 1 | 130–139 | or 80–89 |
| Hypertension Stage 2 | ≥ 140 | or ≥ 90 |
| Hypertensive Crisis (consult doctor immediately) | ≥ 180 | and/or ≥ 120 |
Blood pressure is the force exerted by blood against artery walls, measured in mmHg — systolic during heart contraction, diastolic during expansion. It's affected by age, weight, time of day, activity, climate, altitude, season, caffeine/alcohol, medications, stress, and tight clothing. "White coat hypertension" can elevate clinic readings vs. home readings — home self-monitoring supplements your doctor's data and provides a fuller history. Hypertension is often symptomless ("silent killer") but treatable when caught early; AHA-recommended lifestyle steps include not smoking, reducing salt/fat, maintaining weight, exercising regularly, and getting regular checkups.
| Problem | Cause | Corrective Action |
|---|---|---|
| Nothing appears on display when powered on | Battery drained or wrong polarity | Replace all batteries; check terminal polarity |
| Cuff does not inflate | Battery voltage too low | Replace all batteries |
| Doesn't measure / readings too high or low | Cuff not applied properly; incorrect position; movement; weak/irregular heartbeat | Reapply cuff correctly; sit still with arm at heart level |
| Reading differs from clinic/doctor's office | White coat hypertension or measurement conditions | See "Why measure at home?" section above |
If issues persist, contact your dealer — do not attempt to open or repair the device (voids warranty).
