10. ALIGNMENT PROCEDURES

1. AM IF Adjustment

Input Signal Source
Step
Connection
Signal generator output to
1 transmission *loop antenna.
(*:Standard required loop)
REMARK: For receiving antenna, the adapted one is available.
This adjustment is not necessary normally, because the coil LA06 is preset by the original supplier.
It is necessary when the incorrect usable sense and frequency response.

2. AM (MW) Tracking Adjustment

**Input Signal Source
Step
Connection
Signal generator output to
1
transmission *loop antenna.
(*:Standard required loop)
2
3 Repeat step 1 and 2 until sensitivity be maximized.
3. AM (LW) Tracking Adjustment [N version]
**Input Signal Source
Step
Connection
Signal generator output to
1 transmission *loop antenna.
(*:Standard required loop)
2
Repeat step 1 and 2 until sensitivity be maximized.
