Tuning a Channel.
Press the “Programme” switch until the channel you wish to tune is displayed by the Programme
indicator and the FM / AM indicators. The Frequency indicator will indicate the original setting.
By using the “UP” or “DOWN” switches step to the required frequency.
The Programme indicator will now pulse inviting you to store the new selection by pressing the
“Store” switch using a small screwdriver or similar tool through the front panel hole.
After storing, the Programme indicator will stop pulsing.
Press the “Programme” switch once and the Programme indicator will indicate the next programme.
To tune repeat the above until all channels have been set.
After 7 channels have been selected the Aux. input is selected. The Programme indicator displays an
“A”.
When installing this unit it is important to connect a suitable aerial.
A dipole or a multi-element directional antenna, mounted externally should give optimum FM
reception. For AM a loop, long whip or long wire aerial will suit.
Both FM and AM aerials should be wired using a coax type cable, and the cable kept to a minimum
length for best results.
Please note. An internal battery supports the memory of the tuner module. If the module fails to
operate correctly when first switched on then the battery voltage may have dropped too low to
maintain the memory. Once this has happened the tuner module must be reset before it can be
reprogrammed.
To reset the tuner the unit must be turned off and the “STORE” button held in whilst switching the
power back on. This will restore all pre-set stations to their default settings of 89.1MHz for FM
stations and 909KHz for AM stations.
