The preset changes unexpectedly with a multichannel

source

If you are using a non-Meridian source on the MHR SmartLink

input, proprietary data may cause preset switching.

• Select Force this source to be six-channel for the source. See

the

Meridian Configuration Program Guide

.

Video problems

Poor picture quality

Picture quality may suffer if you do not attend to the following:

• Are you using suitable quality cables with good connectors?

• Is there a ground loop created between any of the components

connected to the G68?

Remember that reception of broadcast or cable signals can be

significantly deteriorated by cross-modulation in the RF domain. It

is unwise to attempt to cascade and mix several video sources, eg

LaserDisc, VCR, etc, to an antenna system.

The picture is very dark or very bright when using a

composite input

This could be due to a DC offset on the video source.

• Try using inputs V3 or V4, which include DC blocking circuitry for

use with set-top boxes and other sources which typically exhibit

this effect.

Radio tuner problems

FM tuner reception is poor

To obtain high-quality stereo reception on FM a good aerial is

essential. Try positioning the aerial at different points in a room;

generally performance is best high up and near a window.

In some areas an external fixed aerial will be necessary. This can be

placed in a loft or mounted externally.

AM tuner reception is poor

Position the antenna to maximise the strength of the station you

want to receive and to reduce interference from other stations on

nearby frequencies.

Position the antenna away from items that generate electrical

interference, such as fluorescent tubes or televisions.

RDS station names are not being received

Not all stations transmit the station name in all areas.

If the station name is not available you can define a preset station

with a name; see the

G Series System Guide
