* TUFL u-con　　There are 2 type of TUFL u-con IC for DVR-310-S.　　(1) Flash type (It is possible to update the firmware.) [Service mode: F]　　(2) Mask type (Part number label on the IC) [Service mode: M]

TUFL u-con IC may easy to be damaged by electrostatic.

* EEPROM (IC2251)

For backup Tuner data.(Pre-set CH, AFT ON/OFF, Skip CH etc.)

Information about timed recording

Other information(state of Volume, remote control mode and last Input positions (Line/ Tuner etc)

* Lithium battery Life time of battery is approx. 5 years.Power of RTC and Backup SRAM are supplied by Lithium battery when AC cord is disconnected.

POWER SUPPLY UNITCheck point

[Service] (Refer to SM p46)　Only Fuse on secondary circuit can be replaced for repair.

If other components parts are faulty, replace whole POWER SUPPLY UNIT for safety regulation.　P101 ! AEK7050 （3A）　P201, P401, P403, P404 ! AEK7067 （2A）

[ Note ]　CN204（Yellow） is vacant for DVR-310H.

This connector is used for HDD unit of DVR-510H.

R6 WRITER UNITCheck point

[Symptom] Not working for DVD[Note] Check whether DVD writer is recognized with Test mode. （S/M 60 page）

[Symptom] Reading and writing problem for Discs.[Check point] Check error rate by service mode.

Check LD(Laser Diode) current by test mode.(RF level is only for your reference, use to compare with other model.)
