– 2 – SECTION 1 ELECTRICAL ADJUSTMENTS NOTE : 1. The adjustments should be performed in the order given. 2. The adjustments and measurements should be perfomed for both L-ch and R-ch unless otherwise indicated. 3. L-ch adjustment should be completed before performing R-ch adjustment. OSCILLATING FREQUENCY Adjustment Procedure : No signal state. 1. Connect the frequency counter to TP (CL4) (L-ch) and TP (CL- 54) (R-ch). 2. Adjust with RV1 (L-ch) and RV2 (R-ch) so that the reading on the frequency counter becomes the specified value. Specified Value: L-ch RV1 2.3MHz ±2kHz R-ch RV2 2.8MHz ±2kHz Connection and Adjustments Location : [TX BOARD] (Conductor side) regulated dc power suppluy 9 Vdc frequency counter TP (CL4) TP (CL54) TP (CL54) (R-ch) TP(CL4) (L-ch) RV2 (R-ch) RV1 (L-ch) [TX BOARD] (Component side) Oscillating frequency adjustment MICROFILM TMR-IF330R SERVICE MANUAL INFRARED TRANSMITTER SPECIFICATIONS AEP Model UK Model TMR-IF330R is the component model block one in MDR-IF330RK.
