Common questions about manuals, registration, and support for this brand.
The IHB (Irregular Heart Beat) symbol indicates that an irregular heartbeat was detected during the measurement. If this symbol appears frequently, it is recommended to consult a physician.
Remove the battery cover on the bottom or back of the unit. Insert new alkaline batteries (usually AA or AAA depending on the model) ensuring the polarities (+ and -) match the diagram in the compartment. Do not mix old and new batteries.
An error code often indicates movement during measurement or that the cuff is not wrapped correctly. Ensure the cuff is applied snugly to the bare skin at heart level and remain still and silent during the measurement.
Measure the circumference of your upper arm. A&D typically offers Adult cuffs (22-32 cm) and Large Adult cuffs (31-45 cm). Use the index mark printed on the cuff to verify it falls within the proper fit range when wrapped around your arm.
Most A&D monitors are designed for standard alkaline batteries (LR6 or LR03). While rechargeable batteries may work, they might not provide the expected battery life or accurate low-battery warnings due to voltage differences.
