SECTION 4 MECHANICAL ADJUSTMENTS
1. Clean the following parts with a denatured-alcohol-moistene swab: playback head pinch roller rubber belt capstan idlers 2. Demagnetize the playback head with a head demagnetizer. 3. Do not use a magnetized screwdriver for the adjustments. 4. After the adjustments, apply suitable locking compound to the parts adjusted. 5. The adjustments should be performed with the power supply voltage unless otherwise noted. · Torque Measurement

TEST MODE This set have the test mode function. In the test mode, FM Auto Scan/Stop Level and AM (MW) Auto Scan/Stop Level adjustments can be performed easier than it in ordinary procedure. 1. Set the "power select" switch (S501) is "A" position. 2. Turn ON the regulated power supply. (All LEDs on the set lights up, and the clock is displayed.) Note: Press the [OFF] button, if the clock is not displayed. 3. Push the preset [4] button. 4. Push the preset [5] button. 5. Press the preset [1] button for more than two seconds. 6. Then the display indicates all lights, the test mode is set. 1. Push the [OFF] button. 2. Return the "power select" switch (S501) to initially set position.
See the adjustment location from on page 18 for the adjustment.
