Alignment Procedures
Low Current Base Tech 3.5
11) CTCSS Deviation Alignment
a) Press the “#” key on the Front Panel until the second line of the LCD displays “CTC DEVI WID.”
b) Activate
PTT.
c) While monitoring peak FM deviation, adjust the deviation level to obtain 500 Hz ± 10 Hz positive
and negative peak deviation. Enable audio filtering below 300 Hz only. Press the “A” key to
increase or the “B” key to decrease the transmitter wideband CTCSS deviation level.
d) Deactivate
PTT.
e) . Press the “#” key on the Front Panel until the second line of the LCD displays “CTC DEVI NRW.
f) Activate
PTT.
g) While monitoring peak FM deviation, adjust the deviation level to obtain 250 Hz ± 10 Hz positive
and negative peak deviation. Enable audio filtering below 300 Hz only. Press the “A” key to increase
or the “B” key to decrease the transmitter narrowband CTCSS deviation level.
h)
Deactivate PTT.
12) C4FM Digital Deviation Alignment
a) Press the “#” key on the Front Panel until the second line of the LCD displays “DIGITAL DEVI.”
b) Activate
PTT.
c) While monitoring peak FM deviation, adjust the deviation level to obtain 2827 Hz ± 283 Hz positive
and negative peak deviation. Press the “A” key to increase or the “B” key to decrease the
transmitter C4FM digital deviation level.
d) Deactivate
PTT.
e) Exit alignment mode by cycling power to the radio.
f) After radio reset is complete, press the Shift key followed by the number 0 key.
g) Press the number 2 key to transmit the Standard Transmitter Symbol Rate Pattern.
h) Activate
PTT.
i)
Monitor peak FM deviation. Verify that both positive and negative peak deviation levels each fall
within 2544 Hz to 3111 Hz deviation.
j)
Press the number 3 key to transmit the Standard Transmitter Low Deviation Pattern.
k) Monitor peak FM deviation. Verify that both positive and negative peak deviation levels each fall
within 848 Hz to 1037 Hz deviation.
l)
Deactivate PTT.
