Low Temperature T a=-10 V cc=5.0V t=240H Note 2. Heat Cycle -20(0.5H) ∼ +75(0.5H) 20Cycle Note 2. Dropping Test devices shall Be dropper 3 times naturally onto hard wooden board from a 75cm position Note 3. Note 2. 3-2 (electro-optical characteristics) s hall be satisfied after leaving 2 hours in the normal temperature. Note 3. 3-2 (electro-optical characteristics) shall be satisfied and no conditions deforms and destruction of appearance. (excepting deforms of terminals) 5. Inspection standard 5-1. Among electrical characteristics to tal number shall be inspected on items blow 1. Front distance between emitter & detector inspection standard 2. Current consumption 3. H level output voltage 4. L level output voltage 5-2. Items except above mentioned are not inspected particularly, but shall fully satisfy 6. Caution (When use and storage of this device) 6-1. Store and use where there is no force causing transformation or change in quality. 6-2. Store and use where there is no corrosive gas or sea (salt) breeze. 6-3. Store and use where there is no extreme humidity. 6-4. Solder the lead-pin within the condition of ratings. After solder do not add exteriors force. 6-5. Do not wash this device wipe the stains of diode side with a soft cloth you can use the solvent ethyl alcohol or isopropyl one only. 6-6. To prevent static electricity damage to the Pre-AMP, make sure that the human body, the soldering iron is connected to ground before using. 6-7. Put decoupling device between V cc and GND for reduce the noise from power supply line. 6-8. The performance of remote-control system depends on environments condition and ab ility of peripheral parts, Customer should evaluate the performance as total system in those conditions after system up with components such as commander, micon and this receiver
