in. Please enquire with your national licensing authority for
details of permitted channel sets.
The radio will revert to normal operation if it is switched off
then on again.
2.6 Speaker Mute
On models fitted with a telephone handset, lifting the handset
from the cradle will normally mute the front panel loudspeaker
automatically.
If required, this function can be disabled by holding down
D/W while turning the radio on (Fig 2.9). The loudspeaker will
subsequently remain on when the handset is lifted.
As this setting is stored in the radio’s non-volatile memory it
will be remembered even if the radio is totally disconnected
from the power. To restore speaker muting, hold down D/W
again while turning the power on.
