Copyright TEL 31/09/98
Adjust RV210 (line sensitivity) fully clockwise and key the transmitter by earthing
the Tx-Key line. Adjust IC220 via PGM800Win “deviation” to set the peak devia-
tion to ±4.7kHz (±3.8kHz) [±2.3kHz] (you can use either the mouse or up and
down arrow keys).
Sweep the audio frequency from 100Hz to 4kHz and ensure that the maximum
deviation does not exceed ±4.7kHz (±3.8kHz) [±2.3kHz]. Readjust IC220 if neces-
sary via PGM800Win “deviation”.
3.4.6 Line-in Level Adjustment
Set the injected signal at the line input to the required line level (typically -10 to
-20dBm).
Adjust RV210 (line sensitivity) to provide ±3kHz (±2.4kHz) [±1.5kHz] deviation.
3.4.7 CTCSS Encoder
Program a CTCSS tone on the set channel using PGM800Win.
Key the T856/857 with the front panel "Carrier" switch.
Adjust RV805 (CTCSS level adjust) to give 10% system deviation.
Reset the maximum deviation as per Section 3.4.5.
