The iDTV shall be able to find all DVB-T modulated multiplexes whose center frequencies,
F,are located +/-500Khz on a grid:(for Europe)
for 7 and 8 Mhz bandwitdh: F=7*N+2.5 Mhz, where N: 15<=N<=32
for 8Mhz bandwidth: F=8*M+2Mhz , where M: 13<=M<=28 and 59<=M<=107. And

General Product Specification
The monitor enters DPM off (sleep) mode when no H&V sync or
one of H-sync / V-sync input is absent. "No Video Input"
message appears before entering DPM mode. A delay of 30
seconds before entering the power saving state is required to
avoid misunderstanding of display resolution and timing mode
changes.
Power & function recover when both H & V syncs are detected.
The TV enters "TV standby mode" when it's turned off by RC
"Standby/Power" key or SLEEP TIMER function is activated or
no TV signal input for 30 minutes.
