3. Test the PTP (Power Tracking Protection) networks: Test the PTP network for the UPPER
compression driver pair by placing one test lead securely on the UPPER GREEN test point
and the other on the BLACK (common) test point on the Access Card. A properly function-
ing PTP will read no more than 46 ohms (See Figure 8a). If the reading is higher, replace
the SK-3 lamps on the crossover PCB. To test the PTP network for the LOWER compres-
sion driver pair, repeat the above test using the LOWER GREEN test point (See Figure 8b).
4. Unplug the Access Card and re-install the HF shading switch card in exactly the same posi-
tion it was in originally. If applicable, re-attach the security cover, gland nut cover, or NL4
cover.
