Alignment
Vertex Standard Co., Ltd.
3
oscillator shields and circuit boards firmly affixed in place. Also, the test equipment
must be thoroughly warmed up before beginning.
Notes: Signal levels in dB referred to in alignment are based on 0 dBµ = 0.5 µV.
All items tune and/or adjust by Auto-Tuning Mode or Manual Tuning Mode.
PLL Reference Frequency
With the wattmeter, dummy load and frequency counter connected to the antenna
jack.
Tune the transceiver 435.05 MHz (Main-Band) / 868.95 MHz (Sub-Band) and set
the TX power level to low power mode.
Key the transceiver, adjust the counter frequency is within ±100 Hz of 435.05 MHz.
Transmitter Deviation
With the wattmeter, dummy load and deviation meter connected to the antenna
jack.
Inject a 1 kHz audio signal as a level of 80 mV to pin 5 of the
MIC
jack (pin 4 is
Ground).
Key the transmitter on 146.05/440.05 MHz. Adjust the frequency deviation is
within 4.0-4.4 KHz on the deviation meter.
CTCSS Deviation
With the wattmeter, dummy load and deviation meter connected to the antenna
jack.
Key the transmitter on 146.05/440.05 MHz. Adjust the frequency deviation is
within 0.65-0.75 KHz on the deviation meter.
DCS Deviation
With the wattmeter, dummy load and deviation meter connected to the antenna
jack.
Key the transmitter on 146.05/440.05 MHz. Adjust the frequency deviation is
within 0.50-0.60 KHz on the deviation meter.
