1.2 Precautions in Handling (1) Where to Store Store the unit in places meeting the following conditions: • Places not exposed to rain or water. • Ambient storage conditions Ambient temperature: -15 to 60°C (5 to 140°F) Ambient humidity: BT200-N00 ... 5 to 95%RH at 40°C (104°F) (free from condensation) BT200-P00 .... 30 to 80%RH at 40°C (104
(2) Handling Notes • Working temperature and humidity ranges BT200-N00 Ambient temperature: -15 to 55°C (5 to 131°F) Ambient humidity: 5 to 95%RH at 40°C (104°F) (free from condensation) BT200-P00 Ambient temperature: 0 to 50°C (32 to 122°F) Ambient humidity: 30 to 85%RH at 40°C (104°F) (free from condensation) • Do not leave the unit exposed to direct sunlight for an extended period of time. • The LCD (liquid crystal display) may appear dark or the unit may be disabled due to loss of the battery capacity at ambient temperatures below -15°C. (5°F)
The unit is not waterproof. Cover the unit against water when using it outdoors while it is raining. Do not allow the unit to fall into water. • Note on using a transceiver While the unit and the associated equipment are fully protected against high-frequency noise interferences, a transceiver used near the unit and the associated equipment or near their cables could impart high-frequency noise interferences to them. When using a transceiver for the first time, check its possible effects on the transmission loop by bringing it closer to the unit, starting at a point several meters away, to locate the range of safety. • Analog output may change temporally in connecting with BRAIN terminal due to an initial current flowed to it. To prevent communication signal affecting the upper system, it is recommended to install a low-pass filter (approximately 0.1s).
