706400 / OTTOVERSAND [TV]

• Volume control is erratic in lower control range.
• Switching off the two-digit programme sites (10-29, 10-49, 10-99 depending on the individual set). Switchover using the numeric buttons will therefore become quicker. Two-digit programme sites can still be chosen with rocker switch.
• Poor synchronisation. OK when timing is on and via scart.
• Each time the TV is switched on, it goes into AV. You are forced to increase the channels and the sound is too low, it increases very slowly.
• Sound fails sporadically or switches to "optimum" function, particularly in bright rooms.
