z Use non-metallic tuning tools.

z The test equipment and receiver should be warmed up for at least 10 minutes before proceeding with alignment.

z The signal level from the generator should be kept as low as possible to obtain a usable output.

z To tune the frequency, press TUNE, frequency number including decimal point, then press ENT.

If you make a mistake, press CL to delete a single digit or hold CL about 2 seconds to start over.

Adjustment of Coils L23, L24, and L26

Use
non-metallic

Coil

tuning tool

Each coil should be adjusted carefully by changing

the pitch of the coil little by little using a non-metallic

tuning tool as shown in Figure 3.

PCB

Notes:

z Be very careful when doing coil pitch adjustment

because it greatly affects the frequency.

z Secure the coil with glue after alignment. Be sure

the glue is dry and the coil is secured. Also, be

sure that the environmental temperature is nor-

mal. Then, repeat VCO (PLL2 and PLL1) align-

ments on Page 6.

Figure 3

Table 2

Increase the pitch of the coil when the measured volt-

age at TP2 or TP3 is higher than the voltage listed in

Table 2 for the PLL2 VCO alignment, PLL1 VCO1 align-

ment, and PLL1 VCO2 alignment.

Decrease the pitch of the coil when the measured volt-

age at TP2 or TP3 is lower than the voltage listed in

Table 2 for the PLL2 VCO alignment, PLL1 VCO1 align-

ment, and PLL1 VCO2 alignment.
