12、 Circuitry The protection circuitry may have operated if either of the following conditions is noticed: *No sound is heard when the power is supplied. *Sound stops during a performance. The functions of this circuitry is to prevent circuitry damage, for example, the positive and negative speaker con

13、nection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of this unit are used. If this occurs, follow the procedure outlined below: 1. Press the STANDBY/ON button, switch to STANDBY mode. 2. Determine the cause of the problem and correct it. 3. Pr

14、ess the STANDBY/ON button once again, supply the power. Note: When the protection circuitry functions, the unit will not operate unless the STANDBY/ON button is first switched STANDBY and then ON again. 6 SA-HT15P / SA-HT15PC 6 Accessories AC power cord System cable FM indoor antenna AM loop antenna

After enter the remote control code “DIRECT (TUNING)”, the message “OK” will appear for 0.2s second when each button is press one by one. 5. Press “POWER” button on main unit or remote control to exit this mode.

21、 11.4. Activating Self Diagnosis Function (Service Mode) This mode is used for purpose of servicing. 1. With the following operation, the processing of this mode begins. Press and hold down the “HARMONIC BASS” button and the “TUNING DOWN” button, and then press the “POWER” button at the same time. *

22、 At this time, initialize all setting and set the following frequency to Tuner. FL display will display “SERVICE” for 3 seconds. 2. To confirm the uP software Version: Press “TUNING DOWN” button on main unit, “MS085 *” is displayed. 16 SA-HT15P / SA-HT15PC 3. When TUNE UP is pressed, display “SUM *”

23、, “*” is the check sum of ROM for ROM correction. IF there is not ROM, “NO EPROM” is displayed. 4. Press “POWER” button on main unit or remote control to exit this mode. 11.5. The Shutdown And Short Circuit Protection Detection It detects S_DET and DC_DET input port for malfunction. 1. S_DET Functio

24、n (SHORT DETECTION) It is to detect a short in the Power Supply. The detection of S_DET starts after 700ms after POWER ON. After that, it is always detected for any malfunction. Upon detection, the FLD display “F76” and the system is POWER OFF by setting POWER_RELAY port to OFF. 2. DC_DET Function D

25、C_DET (pin 94) on micon is used to detect FAN LOCK. During POWER ON, it will be ignored until ALL_MUTE is released. Upon detection, FLD display “FAN LOCK” and MUTE_ALL will be set to ON. If any button is pressed, it is made to scroll error message “SWITCH OFF POWER”. After Power Off and On,this cond

26、ition is reset, and DC_DET will resume detection of error. It also sets MUTE_SW to ON, to switch OFF the power amplifier. 3. FREQUENCY LIMITER Due to surround speaker change from 6.5 cm to 8 cm. We have to limited certain output level to certain FOR FRONT L/R channel and SURROUND L/R cut off frequen

27、cy in order to avoid speaker noise. 4 ports are used for this purpose. 2 ports are used for front L/R channel, 2 ports for surround L/R channel.
