2 Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C506, C507, C508, C584, C587, C588 & C311 through a 10Ω,5W
resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
·
For E, EG Current consumption at AC 230V, 50 Hz in NO SIGNAL mode should be ~300 mA.
· For EB Current consumption at AC 230V - 240V, 50 Hz in NO SIGNAL mode should be ~300 mA.
3 Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
· No sound is heard when the power is turned on.
· Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are
"shorted", or if speaker systems with an impedance less than the indicated rated impedance of the amplifier areused.
If this occurs, follow the procedure outlines below:
1.Turn off the power.
2.Determine the cause of the problem and correct it.
3.Turn on the power once again after one minute.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.

the TPS operation so that the tape automatically stopsat an interval between music selections.
3.Press [STOPn/-DEMO] and [TAPE ] buttons together on the remote controller. (Recording does not start.)
4.Then, insert a Cr02-positioned blank cassette tape with an erase prevention niche of Side A or B set to the left side.
5.Press [ /FF/ ] button on the remote control. The tape will be forwarded and automatically stopafter two seconds.
6.Remove the cassette tape, and set the other side.
7.Press [ /REW/ ] button on the remote control. The tape will be rewound and automatically stopsafter two seconds.
8.Press [STOPn/-DEMO] button on the unit.
If an error is found, a self-diagnostic key appears on the display.
If several errors are found, the display shows these keys when [STOPn/-DEMO] button is pressed repeatedly. (Ex.: H01 - H02
- F01 - H01)
If no error is found, only the message, “CD TEST” appears on the display.

SA-PM29E / SA-PM29EB / SA-PM29EG

(*1) TPS operation (music search) detects the blank sections between music selections. Therefore, do not use tapes with the
following conditions:
· A blank section that lasts only 4 seconds or less.
· No blank sections (recording through microphones, etc.).
· Music selections that have extremely low pitches or prolonged silent sections (such as classical music).
· and/or Music recorded with fade in/out effect.
