Main risks

• Inaccurate readings due to improper placement, impacts, low battery, out of calibration, or sensor damage.
• Sensor saturation under very high exposures, which may produce unreliable values.
• False sense of security: a dosimeter measures but does not protect against exposure.
• Data loss or corruption due to full memory, unexpected shutdown, moisture, or electrostatic discharge.
• Device failure due to water, dust, extreme temperatures, or use outside the intended conditions.
• Risks associated with batteries (overheating, leakage, or swelling) if punctured, if incompatible chargers are used, or if exposed to heat.

Safe use

• Check the general condition before each use: casing intact, readable display, and sufficient battery level.
• Set the date/time, measurement period, and alarm thresholds in line with the manufacturer's instructions.
• Place the dosimeter in an area representative of personal exposure, without covering the sensor or obstructing the measurement.
• Avoid impacts, pressure, strong vibrations, or bending clips and mounts during measurement.
• Periodically monitor the readings and act with caution in the presence of unusually high values (reduce exposure or move away from the source where possible).
• Record or download the data regularly and, if possible, make backups.
• If you detect inconsistent readings, repeat the measurement or cross-check with another instrument to rule out a fault.

Storage and maintenance

• Store it clean, dry, and protected from dust, moisture, and impacts; avoid direct sunlight and extreme temperatures.
• Do not store the device with the battery fully discharged for long periods; recharge it or replace the batteries as necessary.
• Use only compatible chargers and cables recommended by the manufacturer.
• Clean with a soft, slightly damp cloth; do not use solvents, aerosols, or compressed air on the sensor.
• Perform functional checks and the periodic verifications or calibrations specified by the manufacturer.
• Keep the firmware or software up to date where applicable, always from trusted sources.
• Transport the dosimeter in its pouch or case to avoid impacts and accidental activations.

Restrictions on use

• Do not use it as a substitute for personal protective equipment or as the sole safety measure.
• Do not use it in potentially explosive atmospheres unless the model is specifically rated for it.
• Do not immerse it or expose it to heavy rain or jets of water, unless the device is designed for such use.
• Do not open, modify, or repair it; accuracy may be compromised or the battery may be damaged.
• Keep it out of the reach of children and pets; it contains small parts and batteries.
• Do not use it if it shows cracks, corrosion, a swollen battery, or other signs of damage.
• Do not deliberately bring the sensor close to extreme sources to 'test it', as it may become saturated or deteriorate.
