Remove the following compnnents from the mein circuit board: TR22, C280, C281, C282, C283, C284, L123 by cutting the leads by means oF a cutter. 003- PCB- 301- A- 8409 (pagelO) . lnstall option l (plug-in unit) as indicated on draw ing 003- PCB- 301-
5、A- 8409 (pageiO). Install option 2 as indicated on drawing 003- NRD 001- A- 8409 (page 9). By means of a lowpower soldering iron,solder the wires and coax cables from option 2 to the main print, the VFO and monitor switch, as indicated on drawing 003 PCB- 301- A- 8409 (page 10). Mount the top cover
6、of the NRD-515, without screws. Remove the bottom cover of the NRD-515 and solder the coaxial cables E and F, as indicated on drawing 003- NRD- 002- A- 8409 (page Il). This completes the installation of the 2 options. Mount the bottom cover of the NRD-515. ADJUSTMENT PROCEDURE (option 2) Remove the
7、top cover of the NRO-515 and switch the power on. With the bandwidth switch on AUX; tune the receiver around 00.0 kHz, until you get the highest S-meter reading (between 59 + 40 dB to 59 + 60 dB). a) Adjust L3 on max S-meter reading. b) Adjust L9 on max S-meter reading. 2) This ompletes the adjustme
8、nt of the 2 optjons. 3) Milllnt the top cover. Instead of adjusting the receiver as explained in l) you may choose a weIl known station with Info. stable S readings and adjust for max S-meter adjustment reading. With each option N02 we supply the mounting hard Info. ware. The Option N02 may be insta

General comment: The installation of the Option N02 requires no technical radio skills. However, we believe the installer sh

Page U5 ER5 M ANU A L The option l + 2 from ESKA ELEKTRONIK A/S greatly improves the selectivity and signal-to-noise ratio of your NRD-515 -providing -at the same time -a superb PLL-ECSS reception. Selectivities The comhination of option l + 2 provides you with
