Scanning for Stations

Press and hold the   or   key to automatically scan for stations in the direction 
selected. The scanning will stop when a station is found and the frequency will be 
displayed.

Memory Keys

The GR300BT has 4 preset memory keys which allow up to 4 frequencies to be stored 
and recalled within each band. Because there are two identical AM bands and two 
identical FM bands, this allows 8 AM and 8 FM preset memories. The memories can 
be stored manually or automatically.

Manually Locating and Storing Station Frequencies in the Preset Memories

1. Press the 

BND

 key repeatedly to select the required band.

2.  Briefly press the   or   key to manually step through the frequencies or press and 

hold the   or   key to automatically scan for the next station.

3.  Once the required station is tuned, press and hold one of the four memory keys. 

‘Preset X’ will be displayed when X is the memory number selected (

1

2

3

 or 

4

).

Repeat the steps above to store other frequencies into the preset memories.

NOTE: 

When tuning stations, if the selected frequency has already been stored,  

the preset memory number will be displayed whenever that frequency is selected.

Recalling Stations from the Preset Memories

Select the required band (AM1, AM2, AM3 or AM4) then briefly press the desired 
memory key. The GR300BT will switch to the frequency stored in that memory and the 
selected memory number will be displayed (e.g. Preset 2).

Automatic Music Search (AMS)

The AMS feature allows the GR300BT to search the selected AM or FM band for 
stations and automatically store the first eight stations into the station memories. 
Scanning will start at the lowest frequency in the band and scan upwards storing 
stations as they are located.

NOTE: 

To store only the strongest stations, select ‘Local’ mode before scanning.
