SOFTWARE ADJUSTMENT – continued
Select an operation using [↑] / [↓] keys, then set specified value using [←] / [→] keys on the connected computer keyboard.
ADJUSTMENT
RX 1 • Operating freq. : 136.000 MHz
SENSITIVITY • IF bandwidth
[BPF T1] – • Connect a standard signal generator to
[BPF T4] the antenna connector and set as:
Frequency
Level
Modulation

• Receiving
CONVENIENT:
The BPF T1–BPF T4 can be adjusted automatically.
q-1: Set the cursol to "BPF ALL" on the adjustment program and then push [ENTER] key.
q-2: The connected PC tunes BPF T1–BPF T4 to peak levels.
w-1: Set the cursol to one of BPF T1, T2, T3, or T4 as desired.
w-2: Push [ENTER] key to start tuning.
w-3: Repeat w-1 and w-2 to perform additional BPF tuning.
