2-3-6-1. Transition Keys in Self Check Mode
•  

R  key on the remote commander

• SHUTTLE on the remote commander during Grid Test display

(This unit does not provide JOG/SHUTTLE, and therefore use another DVD remote commander having the JOG/SHUTTLE)

2-3-6-2. Operation and Display
The Self Check Mode transits to this mode when  

R  key is entered. This tests whether each grid turns on individually. The first grid only of

FLD turns on and other grid turn off. Each time the SHUTTLE is entered, the grid is switched in order. When SHUTTLE input is clockwise
or remote number 6 repeatedly, the grid switched in 1 - 2 - 3 direction, or counterclockwise or remote number 4 repeatedly it switches in 3
- 2 - 1 direction.

• Display at the start of Grid Test

• SHUTTLE on the remote commander during Grid Test display

(This model does not provide JOG/SHUTTLE, and therefore use another DVD remote commander having the JOG/SHUTTLE)

LED is switched in order by the input JOG/SHUTTLE on the remote commander. Also, LED ON/OFF is switched by the input of same key
as the function that turns on the LED conncerned.
