2.5.2 Setting the User RCU mode (1) Turn off the power. (2) Press the �REC� and �PAUSE� buttons of the VCR simultaneously. Alternatively, transmit the code �80� from the Jig RCU. 2.6 Mechanism service mode This model has a unique function to enter the mechanism into every operation mode without loading of any cassette tape. This function is called the �Mechanism service mode�. 2.6.1 How to set the �Mechanism service mode� (1) Set the VCR to the Jig RCU mode (the mode in which codes from the Jig RCU can be received) (2) Transmit the code �E5� from the Jig RCU. (3) Release the lug of the Cassette holder and then slide the Cassette holder toward the direction where the Cassette holder is loaded by manually. (4) The cassette holder lowers and, when the loading has completed, the mechanism enters the desired mode. When the VCR is set to the Mechanism service mode, the symbols (�Timer�) in the FDP (LED) are blinked. (7 segment LED display model) 2.6.2 How to exit from the "Mechanism service mode" (1) Unplug the power cord plug from the power outlet. 2.7 Maintenance and inspection 2.7.1 Cleaning Regular cleaning of the transport system parts is desirable but practically impossible. So make it a rule to carry out cleaning of the tape transport system whenever the machine is serviced. When the video head, tape guide and/or brush get soiled, the playback picture may appear inferior or at worst disappear, resulting in possible tape damage. Note: � Absolutely avoid sweeping the upper drum vertically as this will cause damage to the video head. (1) When cleaning the upper drum (especially the video head), soak a piece of closely woven cloth with alcohol and while holding the cloth onto the upper drum by the fingers, turn the upper drum counterclockwise. (2) To clean the parts of the tape transport system other than the upper drum, use a piece of closely woven cloth or a cotton swab soaked with alcohol. (3) After cleaning, make sure that the cleaned parts are completely dry before using the cassette tape.
2.7.2 Lubrication With no need for periodical lubrication, you have only to lubricate new parts after replacement. If any oil or grease on contact parts is soiled, wipe it off and newly lubricate the parts. Note: � See the �mechanism assembly� diagram of the �parts list� for the lubricating or greasing spots, and for the types of oil or grease to be used. 2.7.3 Suggested servicing schedule for main components The following table indicates the suggested period for such service measures as cleaning, lubrication and replacement. In practice, the indicated periods will vary widely according to environmental and usage conditions. However, the indicated components should be inspected when a set is brought for service and the maintenance work performed if necessary. Also note that rubber parts may deform in time, even if the set is not used.
