#<CHANNEL> <ENTER> tunes in to the desired channel (DX404
only).
The valid channels for the DX404 NTSC model are 2-69.
The valid channels for the DX404 PAL model are 2-12 and 21-70.
E.G.:
#25<ENTER> tunes a DX404 to channel 25.
3.2.2 Frequency scanning.
<UP> tunes to the next higher frequency (or Channel for DX404).
<DOWN> tunes to the next lower frequency (or Channel for DX404).
Holding down the <UP> or <DOWN> keys changes the frequency (or
channel) repeatedly.
The factory preset step increment/decrement step is 0.25MHz and
may be changed by typing the following sequence:
*92 <STEP> <ENTER>
Where
<STEP> is a 4 digit number from 0025 to 9975, corresponding to
a minimum step of 0.25MHz and a maximum of 99.75MHz.
E.G.:
*92 1 <ENTER> will increment/decrement 1MHz at a time.
*92 12 <ENTER> will increment/decrement 12MHz at a time.
*92 0025 <ENTER> will increment/decrement 0.25MHz at a time.
*92 1225 <ENTER> will increment/decrement 12.25MHz at a time.
3.2.3 Tuner Select
The DX604 is factory preset to automatically select one of the 4
tuners (The one with the best signal). The number of tuners
participating in the diversity process can be limited via the following
function (<TN> is any tuner number from 1 to 4):
*1# <TN> <ENTER> selects one tuner only.
*1# <TN> <TN> <ENTER> selects two tuners.
*1# <TN> <TN> <TN> <ENTER> selects three tuners out of four.
*1 <ENTER> selects all four tuners (normal mode)
E.G.:
*1#1 <ENTER> locks the output to tuner 1 and stops the diversity.
