Alignment
CTCSS Deviation
ÌSet the transceiver to CH 2 (band center).
ÌTo adjustment, click the left mouse button on the
“CTCSS Modulation” box, then press the [ENTER]
key to open the pop-up window.
ÌUse the [] or [] arrow keys so that the deviation
meter reading is ±0.8 kHz (±0.1 kHz) (for 25 kHz steps)
or ±0.4 kHz (±0.1 kHz) (for 12.5 kHz steps) deviation.
ÌSet the transceiver to CH 2 (band center), then key the
transmitter, and confirm that the deviation is ±0.6 kHz
~ ±0.9 kHz (for 25 kHz steps) or ±0.35 kHz ~ ±0.6
kHz (for 12.5 kHz steps).
ÌPress the “OK” box to lock in the new data.
MAX Ref Deviation
ÌSet the transceiver to CH 2 (band center).
ÌTo adjustment, click the left mouse button on the “MAX
Ref Deviation” box, then press the [ENTER] key to
open the pop-up window.
ÌUse the [] or [] arrow keys so that the deviation
meter reading is ±0.7 kHz (±0.1 kHz) (for 25 kHz steps)
or ±0.45 kHz (±0.1 kHz) (for 12.5 kHz steps) devia-
tion.
ÌPress the “OK” box to lock in the new data.
STD Deviation
ÌSet the transceiver to CH 2 (band center).
ÌInject a 1 kHz tone at –37 dBm to the MIC jack.
ÌTo adjustment, click the left mouse button on the “MIC
Sensitivity” box, then press the [ENTER] key to open
the pop-up window.
DTMF Deviation
ÌSet the transceiver to CH 2 (band center).
ÌTo adjustment, click the left mouse button on the
“DTMF Deviation” box, then press the [ENTER] key
to open the pop-up window.
ÌUse the [] or [] arrow keys so that the deviation
meter reading is ±3.0 kHz (±0.1 kHz) (for 25 kHz steps)
or ±1.5 kHz (±0.1 kHz) (for 12.5 kHz steps) deviation.
ÌPress the “OK” box to lock in the new data.
DCS Deviation
ÌSet the transceiver to CH 3 (high band edge).
ÌTo adjustment, click the left mouse button on the “DCS
Modulation” box, then press the [ENTER] key to open
the pop-up window.
ÌUse the [] or [] arrow keys so that the deviation
meter reading is ±0.7 kHz (±0.1 kHz) (for 25 kHz steps)
or ±0.45 kHz (±0.1 kHz) (for 12.5 kHz steps) devia-
tion.
ÌPress the “OK” box to lock in the new data.
Sensitivity
ÌSet the transceiver to CH 3 (high band edge).
ÌTune the RF signal generator to the same frequency as
the transceiver’s, then set the generator output level to
40 dBµ with ±3.0 kHz deviation @ 1 kHz tone modu-
lation.
ÌTo adjustment, click the left mouse button on the “RX
Sensitivity” box, then press the [ENTER] key to open
the pop-up window.
ÌUse the [] or [] arrow keys to tune for best sensi-
tivity; ultimately, the radio should be aligned so that
the RF signal generator output level is –6 dBµ EMF
(0.25 µV) or less for 12 dB SINAD.
ÌPress the “OK” box to lock in the new data.
This completes the internal alignment routine. To save all
settings and exit, press the “OK” box.
